Just did my first refresh rebuild on a transmission. The 3650 in my stang. Used the tremec manual and these 2 vids to do it. 200k miles and really all it needed was a syncro or 2 and a .004 shim. Noticed a small amount of black rtv from case assembly and orange from the drain/fill got to the spacer between needle bearing but not an issue for the bearing.
This guy is the man I got a 3650 in my car and when ever it give it gas or let off it feels actually like a loose chain on a motorcycle/dirt bike. Changed the output shaft bushing and seal 2 times and it just continues to drip enough to bother me lol. Would love to hear your input on this brother man
Good evening KY! Sounds like you have two issues based on your comment. There are quite a few places that fluid can escape. The only thing to do is thoroughly clean and trace it back to where its coming from. Look to see if its coming from the tail shaft, seam between cases, or maybe detent plugs? The loose chain feeling has me raising an eyebrow. A guy brought me a transmission once that was worked on in a home garage and they forgot to put one of the stainless steel balls in the detent of a needle bearing bushing. The interference fit was loose enough that the bushing would spin freely and it sounded like an old Chrysler starter. Does it make the noise in any particular gear or all the time? Clutch in or out? Neutral while rolling? Shoot me a reply and lets see if we can narrow it down. Thanks, Bob
@@gearsthenbeers9080 I’ve cleaned it again yesterday to make sure it was leaking from the tail shaft and it still is just enough to worry but when I replaced the bushing with a new one it fixed the problem for about 100 miles. The leak isn’t extreme but would be nice to not blow tail shaft seal after seal. With the clunking tho I would have to take a video so you could get a good idea of what I’m trying to say, it jerks only if I’m cruising with a little bit of throttle say in 3 gear I’ll slowly get up to to 2-3k rpm and I suddenly let off it will clunk like a loose chain would feel. I will take a video tomorrow with the shift boot off to maybe get a better understanding because me saying a clunk or jerk could mean a lot of things, my first thought was input shaft bearing but I have no way to tell unless I take the trans out I believe. Thank you for getting back to my comment I really really appreciate it
Good morning KY. Just thinking outside the box a little bit. Tail shaft seal leaks, even after a bushing replacement and several seals, jerking/clunking at times and a noise. I'm beginning to believe, keeping mind this is without physically troubleshooting, that the cone bearing on the output shaft could be your culprit. Lets walk through the logic. You have a noise like a chain on a bicycle. A bearing that has worn to the point of having play on each of the rollers, or scoring on a roller, will make all kinds of racket. You have a clunk. Something is not within tolerance and allowing excess play and shifts position under different power loads and finally, a leak that reappears shortly after installation of a new seal. This all could be failure of that particular bearing. The leak is due to the output shaft having too much lateral movement (up and down) not allowing the seal to function as desired, even damaging the new seal prematurely. The bearing I'm referencing is in Part two at the 15.25 minute mark. Again, without getting my hands on the transmission, its an educated guess, but the symptoms do line up. Thanks, Bob
@kingyamaha9637 Hey bud, I recently came across your post. I seem to have a similar issue with the clunking sound you mentioned for my 03 gt. Did you ever figure out what the issue was?
Can I ask how many liters/qts of trans fluid your son added to the junkyard trans when he got it? Ford originally called for 4. Then revised it twice all the way to 3.2. Just wondering if the faillure occurred with 4qts/liters or 3.2. Also, hooyah aviation?
Sorry about the delayed reply. I've been at the coast fishing! We put 3.2 qts of Mercon V AFT. Not sure I understand the ? after the aviation comment. Its a good career. :)
@@gearsthenbeers9080 mercon v could be the problem calls for dex Merc 3 I believe. I was Navy kind of just assumed you were navy as well. Could be wrong though.
For some reason quite a bit of the video does not have audio, so I'm dubbing over as I edit. Maybe we will be snowed in this weekend and I'll have time to work on it. Thanks!
@@gearsthenbeers9080 When do you think you'll have the rebuild video up? I'm doing my 3650 now. Getting ready to tear down. Had a heck of a time trying to get the darn thing out of the car with long tube headers!
This is awesome man! Please tell me what is the reason for the notchy shifting 1-2, 2-3, when the temperature drops below 50F (first few shifts). And is it normal to have a slight noise in 1st and 2nd at low RPM's as well as in the neutral position (like a slight rattle).
Idk if this is gonna be helpful but for 1-2 2-3 that’s just the tranny being cold. And for the winding noise in 1st I believe it’s normal but the slight knocking is common on these transmission I believe it’s the main bearing being loose or worn or the gears.
That is a very small amount of movement considering you are checking the play at the mainshaft rear bearing. The manual calls for prying in order to check radial movement. Have you been checking by hand? a) pry upwards against output shaft to check radial clearance in mainshaft rear bearing
@@gearsthenbeers9080 Thanks for quick reply. I just want to know is on the rear side there also should be some play? If there should be some play i think it is fine. Year ago I changed Clutch and i didn't feel any play on input shaft but probably there was some play. Now I took care abiut my dyfferential and I just checked is there any play on transmision from output shaft side. I just want to know should be any play on the drive shaft side or not. I can't see what types of bearings are inside and I don't know should I preload it like pinion gear in dyferential or super small play is normal? On the drawing I can see taht play on the front shaft has influance on output shaft and I gues play out there is OK. But I am not sure because I can't see type of bearings on the rear side.
@@pawebogusz8753 some play is perfectly normal. Excessive play is not. Typically what I have seen is that input shaft bearing wear happens much earlier that output shaft bearings. Meaning that excessive play happens in the front end more often. Telling me you have little play, like 0.001 play by hand, makes me believe you are good.
@@gearsthenbeers9080 Great, thanks for informations. Later I will check what is size of that play. But it is so small that i couldn't feel it when there was drive shaft. For example radial play on the axles is few times bigger and I checked it and it is 0.006". So I gues that on transmision is 0.001 or 0.002. Is at the end of output shaft is tapered roller bearing or there is niddle bearing?
very good that video is really something I had planned to do and I dare not but watching the video gives me encouragement thank you. A question. where did you buy that clamp ? is an excellent idea for those of us who don't have a press
Thanks for the great instructional videos, we need a part 3!!!
Thank you all once again for putting these videos together. Excellent work!!!
Glad you like them!

no part 3?

How would you just swap input shaft?

Cen you tell me, is it normal to have super small play on output shaft?
I have about 0.001" of radial play.
