Diagnosing Ford F150 Harsh Downshift/Drive Apply 

Wow - this is probably the clearest video of diagnostics and repair ever posted to the internet. Excellent job - thank you so much!

Glad I found your channel. I have a 15 transit 350 with 3.7. 6r80. Codes P0706,0707,0712,0715 I have been having this vibration sound for a long time, I would describe it like a low bass sound, from big sound system. It comes and goes at any speed above prob 40mph. It will sometimes happen every few seconds and it last for a second or 2. We now have 135k and it started 50k or so ago. I have taken it to several shops and they all say it’s tires or shocks or something and never fixed the problem. Last week I was headed up in elevation on a road trip, no trailer. And I was noticing the rpm would bounce +\- 200, when the sound happens. Then, the sound went away. Approx 50miles later I noticed fluid getting on my rear Windows. I kept driving and made it the next 100 miles to our destination. During the 100 miles, it didn’t ever shift down when pulling hills, it stayed in 6. Even if I manually tried selecting another gear, it wouldn’t allow me to change. After getting into town, I shut it off and when restarted tried, it shifts hard to reverse and drive. It operated fine in R. But feels like I’m still starting in a higher gear. We trailered it back to our town. Where I now have it and am ready to work on it. What are your thoughts? I purchased: lead frame, case of fluid, filter, and it was all here by the time we got home. Now I’m thinking torque converter too. Or am I too far into it and should just bite bullet and order a trans? Where would the fluid have come from? It looks wet on bottom of bell housing…

Thank you for sharing and for taking the time to explain things. Local parts store scanned my 2009 F150. U0121 (ABS lost comms with abs “non mil”) Where i’m confused is it stated on his scan tool to replace TCM and reprogram TCM. Which had me thinking…I do recall that my truck will occasionally have longer shifting leaving for work in the morning.

This is one smart dude! Thanks for the video and explanations.

Thank you Mike outstanding video mark mangano dependable auto

You guy's are great thanks for in info haven't done many trans since fmx,c4,c6 all good 3 speeds a few fordomatics 2 speed thanks again

Thank you, this is my exact problem on 2015 f150

Thanks for sharing your knowledge

Awesome information 👍🏻👍🏻

Awesomeness, keep up the good work 👍🏻 !!!

Thank you that’s great info

That’s good to know. I really thought it would be the connector assembly. I’ll have to look into the SSA on my Raptor. Does the same in 4th gear. Thank you!

Thank you sir

I laughed when i seen the guy, but pretty smart fella. Looks like he had it nailed off the get, thanks for the video. Seemed like a lot of labor for a shift solenoid?

Awesome explanation!!! Thank you for sharing your knowledge. My 6R80 hard shifts when cold from 1st to 2nd gear but only do that 2 or 3 times after I have stopped twice or three times during the first driving cycle of the day? Why not on the first time shifting? Why only after the truck is being parked for several hours? (usually overnight) Can anybody explain this? Once I have gone thru the first driving cycle of the day it goes away? Thanks in advance...

I have a Ford 4r75e transmission that shutters and stalls when brakes are applied. What causes that? Thank you for sharing.

Im having the exact same issue with my 2012 f150 ,i wish you're shop was here in las vegas.

I wonder how much the new fluid helped in solving the issue?

How do you calibrate the solenoids? Please help

Can it test good and still malfunction on operations? sometimes electrical can skip a beat?

Mike....would replacing the lead frame give one the same results? Thanks

when you see odd man you know that you car in good hands good jop👍

I have the same issue but 1st & 2nd gear harsh shifting, changed solenoid valve and it shifts fine and in the morning back to the same issue and the transmission tech guy told me it’s the valve body $1100, the transmission is fully built to handle 1000hp. Or he said it might be a tune.

So which solenoid did you replace exactly and what part number

My f 150 2009 love this truck my problem is that starts and goes to all 6 speed but than if I stop o slodown and take off it feels like is in 3rd gear. Take off in third gear and don't upshift o down shift have to stop on side of road turn engine off. And is ok but than after driving light on dashboard

I have a 2013 f 150 that makes a whooping noise shifting from 3 to 4gear. It also sometime has a hard shift through the same gears. I took it to a local Ford dealership and they was no help at all. What do you think?

hi do you know howto transsfr part to 2016 5.0 6 speed hard shift 2nd to 3rd

Hello from Canada! Thanks for this great video! F150 3.7L 4x4 mfd 03/11 SR80 1-2 shift is rough all the time, under hard acceleration it’s a violent shift into 2nd. No wrench, no codes at all for transmission. Ford replaced the lead frame, No difference. Now they want $3400CAD just to open it up to see what’s wrong with it. I just bought the truck a month ago and really regretting it. Any advice on what might cause this?

Great video!!! I wish you were local. Can the adaptive shifting be reset by just disconnecting the battery or does it need to be done with a scanner? I have a Ford F150 (6R80) built on 08/12. Thank you!!!

My 2017 Ford ranger XLT AUTOMATIC is doing the same thing. Sydney Australia

Thats parthcles from the fluid sticking to the selnoids. Replace the lead frame and use the foam gasket .

ford is replacing my molded lead frame on my 2013 f150 this week. Extended warranty covers 2012 and 2013's at this point I believe.

I have send my car to the Service Centre for replace the rear tyre sensor, and after that the mechanic suggest to update my car software for better condition After finished software installation, there are two symptoms coming out • Car temperature indicator go to maximum level • Very Hard Knocking when I shift N to D gear Senior Mechanic take over this to find the problem occur and made some software alteration to normalise the condition. The senior mechanic can only normalise the high temperature problem but can’t soft the hard knocking problem and they said that they could not replicate the problem Any idea what it can be. It only happens in first gear. All the rest of the gears shifts smoothly with no problem. This happens even when the car has warmed up and even after an hour of driving.

What do you say about the recall lead frame problem?? Could it cause total transmission failure if shifting in acceleration from 55-65 on dry pavement back to first??!

I'm having a harsh 5 to 4 shift like in your video. Is this a similar solution for a 2015 f150

I have a 2021 F-150 XLT 10 speed and I’m stating to have the exact same issue between 3rd and 2nd or when it goes from 3rd and skips to 1st on downshift…only 27k miles…Ford is telling me due to supply chain issues they could have it work weeks…..

This guy knows his stuff! I have a weird issue with my 2011 F150 6r80. In the morning, the first time it shifts from 2nd to 3rd, its a very harsh shift. I usually drive slowly out of my neighborhood, so it's not an issue with agressive driving. After that first shift cycle, it's fine for the remainder of the day. I had fluid and filter changed less than 10,000 miles ago, and the shop I use, I trust implicitly, proper Ford LV fluid and motorcraft filter were installed. Truck is driven gently, and exhibits no issues other than this. No warning lights either.

Simple excellence by men the lawyers, doctors, and politicians foolishly do not consider to be "Professionals" on par with themselves. I also learned this is NOT something I'm going to be doing by myself on ramps outside on the dirt & gravel here in Montana.

Good day sir, I'm from South Africa, i drive a 3.2 5 cyllinder 2011 Ford Ranger with identical issues that you describe. My vehicle has also that heavy lash when it shift between fourth and fifth, it's also very hard on the downshift.Would you suggest that i also try and replace my SSA Solenoid? The garages here want to charge me R 25000.00 South African rand, approximately 1740.USD. Any suggestions? The vehicle has 237002 km on the clock already.

Hi guys, I have a Ranger 3.2 with 6R80. Can someone help where to buy it? Ebay unbranded are a good option? Has someone use it?

Cool pants !

My 2016 F 150 with a 5.0 at hwy speeds ( 70 to 80 ) sometimes has a harsh down shift from 6 to 5 when you normally accelerate or start up an incline or hill . It has 40,000 miles and was serviced at 25,000 with filter and mercon LV , any ideas ? Otherwise it preforms normal. Never any towing !

I have a 2011 6.2 with 267,000miles. My trans started acting up March 5 2021, the wrench sign and engine light came up while waiting to get gas, and code p0770 came up with a scanner and then March 8 it disappeared, March 10 driving on the freeway it was stuck on 3rd gear and wouldnt up shift, had to pull over, turn off truck then drove it around the street it was stuck for awhile and then started normal again but with engine light still on.

What if it works and then after a few minutes no movement at all forwards or reverse Let it cool down and it go in reverse and not forward at all

I have a 2013 f150 3 weeks before the transmission recall came out, my truck shifted to 1 st gear going over 70mph and destroyed trans $4600.00 later and 19 days before the recall they will not honor the recall and refund my money!!!!!! this only the 23rd Ford vehicle my family has purchased in the last 25 years NEVER AGAIN.

The whole brand new valve body is actually cheaper than the time and cost to diagnose the valve body, my opinion just buy the new valve body and just pay for the installation.

My 2007 Tacoma computer controlled transmission still works flawlessly ,retired transmission rebuilder.

Why can't my fix be that easy ?

Throw parts at it the hope it fixes it typical

Why are his pants around his ribs

im confused so the selonoid you tested and said was ok was not? ssa whats that mean

90% of the shops just said rebuild the transmission is bad
