4F27E Rebuild 

Once again, thanks for taking the time. I think this is one of your better videos. You really took the time to show some of the things you sometimes breeze through (and I mean absolutely ZERO disrespect). This one is surprisingly simple. I have a manual ordered but it didn’t make it in time. I was noticing that it looks like in a pinch the actual transmission portion of this unit could be rebuilt without even splitting the case open. Take the pump out and the rear cover and everything you need to take out will come out. Just a thought.

I just wanted to add something I figured out on this unit! The shifter doesn’t like to go into the park position when it’s upside down!!! The rod that pushes the park lever down gets hung up on the guide for some reason. Flip it over and try that before you start tearing it back apart like I did!

Tom, you are my new best friend! I watched your video's @ naseum insuring I would rebuild my transmission properly. I was able to bore the servo, resurface my valve body, rebuild the overdrive/reverse drum with your help. My car works better than ever!!!! thank you!!! thank you!!! thank you!!!

i just got my trans completed watching your videos and reading your comments, appreciate it, super helpful. Some time in the next 2 weeks ill get it installed and see if it works hahaha btw at 1:15:21 you mention the hole not lining up with anything. the technical service manual actually shows a DTR sensor alignment tool number 307-415 that bolts on and lines up with the hole.

Excellent work from a master

Thank,s for the video. I have learned a lot.

Hi, rebuilding this transmission has been a nightmare. First, the tranny started to slip a little. When I checked the fluid, I discovered that the oil was a bit dirty and has not been changed in a couple of years. Upon changing the oil, I noticed that there were No metal filings nor any excessive gunk in the pan/magnet. In my opinion, it looked much better than the average when it comes to wear and tear on it. I thought that by changing the fluid just in time, it would have taken care of the problem ; just like it happened in the past with a Toyota. I know it's comparing apples to oranges...lol. However, it continued to slip (delayed changing of gear) hence I decided to do a complete rebuild, hence why I asked the question about the clutches. Now that the transmission was rebuilt by a transmission repair technician, NOTHING was discovered that was obvious to the cause of the problem (clutches and band had about 60% life on it) so I decided to do the complete overhaul anyway. After the overhaul by one technician, the transmission did not go into any of the forward gears, so that technician gave up and told me to take the car to someone else who knows and fixes Ford. So, I took it to a "specialist"who knows about Fords and had it repaired. He told me that I needed a Valve-body, so he sourced a used one and went over the entire transmission and did the repairs. When I got the car back, everything was working fine except that I was getting a very Hard Shift on the Second Gear and a Slightly hard shift on the Third gear. I drove the car for a little while and he did a Relearn on the tranny, but it had no effect. I took the car back to him and he told me that he has to get another Valve-body and replace it to which he did. After installing the Second Valve-body, he told me that it is NOT Hard-Shifting any more, but it is now Slipping. The million dollar question to you is: What do you think that could be causing the problem of Hard-Shifting? I find it strange that the Valve-body would cause both effect. I thought that the accumulators would be responsible for the Hard-Shifting of the gears. I am in desperate need of your expert advice. Much thanks.

So I’m trying to help the 18 year old neighbor kid still in HighSchool and works full time. He has a 2011 ford focus. He doesn’t have the money to take it in somewhere, plus it’s a good life lesson to know how to fix things. But anyways, It wouldn’t shift past 3rd gear unless you really rev the rpm. Didn’t realize the servo bore might be the issue before I replaced the solenoids and clean the valve body with him. We should have waited until the next day when we had better light before putting it all back in. Because the Manual shift lever wasn’t in the slot on the park prawl, and when we shifted it I think it became bent. It doesn’t move freely inside the valve body anymore. When you slide it in to bout the 3rd circle it stops. I have looked everywhere for this replacement part but I don’t see where they sell it. Called Ford and they said it was $225. I don’t think he was looking at the right part. Either way going back to it being for a 18 year old that’s his entire week’s paycheck. Not to mention the cost of the rebuild kit, and what he already paid for the solenoids and fluid. I’m trying to keep the cost under $500 to help him, which I’m gonna loan him for the parts. Any idea where I can get the Manual position lever from rather quickly. My wife and I take turns getting him to and from work, so I’m looking to get his car back up and running sooner rather than later.

Dang, replacing solenoid block might be not easy without taking down the transmission.. 2007 mazda 2, got a hit under the oil sump, and it crushed the EPC solenoid. Replaced oil sump, filter, and EPC, but now shifting hard between 1-2-3 gears. Also big shaking when I put it in R while it's cold. Car showing p0745 00 solenoid circuit malfunction error... I hope replacing other 5 solenoids just solves the problem :( the springs may pop out if I pull out the whole circult.

Good evening, I have Code p0732, I have a 2003 Focus, it presents this error sometimes and starts to strain a lot to change gears. What do you think it could be? I replaced all the solenoids but it didn't help. When I'm driving very slowly with the car between gear 1 and 2 it shows the error on the dashboard, but really, I'm having a problem in gear 2.... thanks thanks

Hi Tom I had code p0767 on my 2013 ford transit changed the solenoids and no luck it’s drives good but when it’s time to shift to second it revs high then lowers assuming it went to 3rd looked online some one mentioned to check the band “ now I found out about the servo is there a way to check it ? I don’t want to tear more of the transmission apart it’s still in the van on jack stands .. also when I took the cover off the band was loose came off easy I didn’t know there was a tension bolt so basically I just wiggled it off

I have 2013 ford transit connect, it drives fine and low and second I’ve lost overdrive and reverse and when you get up to route 35 to 4000 RPMs in drive it tries to slip any ideas I have changed the two shifts solenoids put in new fluid in it and also put a new filter. Still not working. Any suggestions

I wonder why he doesn't do the cross drill for full time lube on the valve body?

Hey great video. I'm thinking of taking apart the bottom end of my transmission and replacing the accumulator springs and valve body assembly as that's what I've been told up to this point would fix it. When cold is has one of the roughest shifts from first the second and a slight bump from second to third. When warm they both just have a slight bump when shifting. When cold of I accelerate a little, let off the gas, let it up shift and then get back on the gas it shifts no problem. Do you believe replacing these two things would help fix the issue?

If I changed the band out and haven't touched the bolt, am I able to just continue using the original servo band bolt that's already in place or is new bolt mandatory?

what is the flat shim like tool you use here for getting the piston installed? 8:51 is that bought or custom made?

How common do the differentials go bad? It feels like mine is missing teeth. Am i able to pull the pump and split the case to replace it without tearing the whole transmission apart. It was just rebuilt 8k miles ago but im the new owner so no warranty. Thank you.

I have a general rebuilding question. When you install new clutch packs how often is the stack height / clearance within tolerance? Ive noticed with my rebuild kit, im having to mix old metal and new clutch to get proper clearance. i even sanded down the snap ring on one. is that something you normally go through? Also, Is it any problem to reuse an old clutch ring with some new ones? my kit is missing one ring and i really want to reuse an old one so i can get it done. I wasnt sure where to order parts from, i found my kit on global transmissions. they use raybestos for the clutch packs, i have no idea if they are a good brand or not. thanks

hello,I have a 2005 ford focus zx-4.with the same trans.when vehicle is cold,shiting from park to drive,it bumps hard.no other problems.whet it is warm,there is no problems.any ideas?

Great video! I have a 2012 Transit Connect with this transmission. The rear engine main seal looks like it's going out. I'll be putting in the 3 seals on the transmission even though they don't leak while I'm at it. The Transmission has 165,000 miles and no problems. Would you open the covers to check the clutch plates/band and all or just leave it alone if there is no metal in the pan? What rebuild kit should I buy to have on hand for the seals and all?

54:48 What's the deal with the shims? How do you determine the thickness needed?

Hello, I have a question, is the automatic transmission of the focus mk2 the same as that of the focus mk1?

Thank you for the video, I am considering overhauling my 2013 transit connect transmission. It will not engage in overhaul and displays the wrench light on the dash. It has 112k miles on it. I've replaced the fluid and filter with no change, and no codes present. Any ideas about what it may possibly be? Thanks in advance!

At 5:25 how did you get that snap ring installed?

Hi, I have a Ford Focus MK2 (2006)European built with a 4F27E transmission (I believe, not confirmed) and I want to rebuild it. How do I know for sure if my transmission carry a single sided or a double sided clutches in order to purchase the right kit? My car has about 80K miles, and I have never changed the oil in about 6 years of ownership. I noticed a feedback on the transmission at one time, so I immediately checked the oil. I noticed the oil was VERY dirty (brown river water in color) so I changed it myself. I noticed that there were NO metal filings nor any excessive clutch material in the pan, next to nothing at all. I have seen much worse that didn't have a problem. Overall, everything looked, I would say better than average inside the pan. After changing the oil, the transmission started giving different codes indicating Shift Solenoid C fault, Engine System Defaults, and Transmission Gear Ratio Incorrect. Sometimes the car would have a Hard Shift and a prolong shift from first to second gear. I also noticed that the car was stuck in high gear and would take off in same gear. I changed out the oil again and put back in the same old solenoid since the new solenoid continued giving the same code. The solenoid code went away afterwards even with the old one. What are your thoughts as to what could be the problem/issue with my transmission? Someone mentioned that the pressure valve could be sticking and causing the problem. I also saw that they are selling a modified shift kit for this transmission. Would that help or fix my situation? Thank you for your help.

How hard is it to rebuild at home a 4F27E on a 2006 mazda 3s automatic with a rebuild kit from online ? ive done timing chains / lifters / valve stems / transmission valve bodies scale 1 thru 10 10 being hardest ?

My 2001 focus has no 2nd or 4th gear. Tried the solenoids, but no dice.

What fluid do you recommend for these transmissions?

I have mazda familia 2001, it's shifting 1st 2nd reving high, in some case it jerks. Others are smooth shifting. When i go very light on the throttle it smooths out. Or i have rev higher to get it smooth. Any idea what this could be?

Hi Tom, I just finished a 4F27E complete rebuild with new TC and now have high line pressure at an idle/ stall in all gear ranges, but am also hearing/ getting what sounds like a pump/ converter whining noise only when in reverse or forward ranges, not in park or neutral? Only drove it around the block once and shifts are timed good, no slippage, no leaks & no codes. Thanks for any/ all help!

Question. I just had my 4F27E rebuilt by a local shop for $3k. 1yr & 22k miles later, after the warranty ended, I'm getting a code P0971, an Solenoid A is getting stuck. I'm thinking of upgrading to the TransGo performan upgrade kits. How hard are they to install, being a basic home-garage mechanic?

Thanks for the good video! I have 4 of the 2010-2012 ford transit connect work vans and have to replace the transmissions every 65-100k miles. Employees are hard on them. I’m very mechanically inclined and considering getting any special tools required to rebuild them myself at this point. I’ve bought ford reman transmissions and had local shops rebuild and they always wear prematurely. Any advice for making this transmission more durable or should I just buy the servo bore tool haha

Where is your shop located? I have a 2007 Focus and need trans rebuilt.

I did a basic rebuild on one. Clutches, seals etc. The problem now is it slams into gear when shifted from P to D and sometimes P to R. Other than that it operates fine. The motor and trans mounts are new. Fluid level is good. Do you have any ideas what I should look at? I'm thinking A&B solenoids.

I have a 2007 Mazda 3. No A.T. lights or check engine light. But will not shift into reverse when cold. After it warms up. Everything is fine. Tried changing oil and filter. Still same problem. Any clue?Thanks

For a 2006 Focus (4F27E), transmission has a distinct and very quick rattle on the 2-3 upshift only. Noisier when warmed up. Any idea what this might be? Transmission shop wants to rebuild, I am just wondering if this is might be a typical noise with a simple fix? Solenoid, valve body, band maybe? Anyone heard this before?

Saludos he tratado de reparar mi transmision de mazda protege...ahora no se que pasa las llantas mecanicanente no giran hacia atras..solo hacia el frente...que puede haber mal?

Hello , I have a 2014 ford transit connect and it seems that on 3rd gear. It revs and then shifts only when it’s cold any suggestions? Thanks

hi, what atf you use? thaks

Very good job I wish I could pay you to walk me through one of those. But I feel confident I can do it after watching your video. I have a 2007 ford fusion automatic transmission like this. Car is straining to move forward and back.

That transmission is sh1t jaja 😔 2 to 3 gear
