Holy crap!!! 6 videos to find this one... "wavy snap ring" Yeah, I couldn't figure out where it went. I knew the drum, but couldn't remember whether it held down the spring or the clutches. Thank you for being thorough!
Good stuff. I just pulled apart my 1st transmission. An 04 4r70w. Leaking out front and no forward gears. Got a few more things to check now. Good tips on what to replace
Perhaps you can help, on my 4r70w the car moves slowly forward in drive, seems like it struggles, the revolutions just climb up. Well I have noticed that if i rev it up to about 5000 rpm the transmission engages and works fine and it drives and it shifts gears with no problem. As soon as i let it coast to a stop (when it gets to about 25 mph) it feels as if it starts struggling and once it completely stops the same thing happens again, I have to rev it up in order for it to shift into gear. I have changed all the solenoids in the valve body but no luck. What do you think could be the issue? Would I need a complete rebuild?
Gary Ferraro, I'm a new subscriber. I have a trany problem and I bet with your expertise and extensive knowledge you'll be able to tell me what the failed component is based on the rather unique symptoms. Is there a way I can pay you for some phone time? The vehicle is a 2010 Crown Vic Police interceptor I just acquired. 75,000 miles and 10,000 hours on the clock. When the gear selector is in drive and the overdrive is disabled the trans doesn't make the 3rd gear (direct) shift it will remain in 2nd past the redline RPM. When the overdrive is enabled and the trans tries to do 3rd it neutrals. Then if you put it to the floor it goes back into 2nd. It has never gone into 4th for me. I don't have a reliable source to get a history on the car. If it is likely a valve body issue I will attempt to fix it myself. If the trany needs to be pulled I will likely make this a parts car and put it on a salvage title until I find a trany or someone needs an engine then I'll sell the whole car to them. I don't want to pull the pan unless I'm %70 sure it is a valve body issue. I have about $1000 in the car right now
Hello William, So if you have no 3rd or it "runs away" in 3rd, this is a problem with the direct clutch, pretty common problem, not much can be done other than to pull the trans. If it runsaway in 3rd it will not go to 4th, the direct clutch is on in 3rd and 4th, the front band also comes on for 4th. Thank you for subscribing.
Hello Gary, thanks for an excellent video. I have a 4r70w in which the vehicle sounds like a transbrake being applied when in reverse (engine loads w/o movement). The vehicle goes forward in N & forward gears. All forward gears work smoothly (upshift and downshift). Primary pressure was 70psi (idle) and 100psi (WOT). I checked the gear selector at the transmission w/o dropping the pan to make sure it was selecting the correct gears. I'm thinking this is a servo that isn't releasing (1-2 apply?)? If I drop the valve body and the servos are fine, what are your thoughts on where to go from there? Thank you.
Bill Myette Bill, the problem with your trans may be that the forward clutch is locked on and won't release, (the clutches and steels are locked together so it's always on). When you select reverse now you have the reverse clutch and band applied and the forward clutch is applied because it's locked together, end result the car won't move in reverse but will move forward in neutral. Not much you can do with this, trans will have to come out to be repaired or overhauled. Gary
Thank you for all the information 🙏 Im doing a project truck 2001 f150 5.4 v8 Teardown my transmission already (4r70w) pistons bad, bands and forward clutch burned, i ordered all the parts i need expect solenoids What color and kind of solenoids should i use?? Thank you very much
Shift solenoids and lock-up solenoids, i usually go OE, EPC solenoid either OE or Borg warner, I go with Borg warner on that. What do you mean by color?
The colors are for specific years. Can’t just use anyone. Let me ask my rep tomorrow morning They use different brackets too I will find out and let you know
I have a 4r70 that i wanna rebuild to put in place of my 4r75e but im worry that the output shaft from the 4r70w is different, the 4r70w came from a 06 e350 and the 4r75e is for a 05 f150 with the 5.4
Awesome Video! Question if I may did you make a rebuild video? the teardown was awesome and well like everyone else I have a problem lol No reverse drives perfect but where I live mostly no turnarounds ugg
Bellville return spring is broken what purpose does it serve exactly it was broken in 3 places now I need to know what would break it in 3 places ?? im thinking someone slamming it in reverse
@@GaryFerraro i have a 97 ford f150 5.4 v8 4x4 it runs great ...the tranmission fluid looks brand new pink...... but when i floor d gas to go fast from a red light..,. it will kinda delay a little to shift and when it does it has hard shifts but if i drive normal it shifts perfect what could cause that?
@@GaryFerraro its a hard shift not to violant but u can feel it shift n like a small jump.... I was thinking it could be the solenoids or maybe or a brocken spring in accumulators
I have a question on the rev clutch pack the ones I got seem to have a tooth missing on the inner part of the ring is this common or something they did to fix something else? hoping your on ugg
hopefully, u got email on your phone I broke a pc of cartilage off in my right knee its killing me and I have to get this done by tomorrow my r&r guy aka kid i am paying is coming tomorrow to put it in ugg cant you teleport here and fix it lmao i will email tho
I just want to say Thank you to Mr. Ferraro for taking the time to answer my replies and a couple E-Mails most trans guys have attitudes but I think Mr. Ferraro understands that there are those of us that are trying. however I did not say I was done lol
Gary Ferraro I worked at benchmark transmission for 5yrs never rebuilt a trans was learning before I got fired because of my dick manager. Anyway I was going to go and rebuild it myself I was friends with the pot head boss and he taught me some stuff
@@scottclary6342 Depending on the year, in 2009 they changed the internal harness from hard wire to soft wire. Overhaul kits are the same and the gear train from from 2004 and up is the same. Since the internal harness changed the solenoids changed as well
@@GaryFerraro thanks but y put a new clutches and is same thing the splains are ok i gone craisy when take to a road 3 gear the rpm goin up their feels neutral sorry for my inglés
@@GaryFerraro im check two times whit air and apli fine the only problem found was the seals and some clutches burn and i put all the seals and friction clutches whit no lucky i realy presure you help
