Thread: trans build

I dont post here much so heres a little backround. I bought a 99 GTP coupe last november. Chipped a piston in march after driving it 7k miles. Tore the whole car down to rebuild the engine and decided to build the trans while I had the engine out. Me and my dad run a full time transmission business and the trans has 140K on it so it only made sense. The car is getting cam, headers, tune, 3.4 so I wanted to build a trans that I wouldnt have to pull out and fix once a year. on to the build.

hoisted the trans out of the car after I had the engine out, simple enough.



Got the trans on my tear down bench



Fluid wasnt looking so fresh,



Little bit of debris, not all that bad compared to a lot of transmissions I have seen but this one still worked fine.



Got the pump, valve body and channel plate off.



First worn part, how many more 4th shifts were left in the stock 4th hub? ha, not many. I have never seen one come out that looked any better than this.





We havent done a single chain conversion yet because we dont see a whole lot of 65E's. The ones we do see are generally in mini-vans and the such so people dont want high performance upgrades and stuff. So here we are mocking up the sprockets and figuring out whats so "special" about these $400 kits. haha not much to it really.



more to come as we delve further into it, this is all i have time to post right now.

The trans is all tore down and mostly ready to go back together I just decided to post a thread about it finally. I was in the middle of building a 4R100 for a F250 when we were doing this 2 weeks ago, thats whats on my assembly bench.




The other day I tore the final drive completely down. I am having the sungear, planetary gears and spider gears all iso-rem treated. My original final drive sungear was in pretty rough shape and transtar can only get 38 tooth final drive sungears new. You can buy a used one from them for $30 but they dont inspect them very close and half the time you end up with one thats just as bad as the one you are trying to replace. So I ordered a brand new 34 tooth sungear from my handy dandy dealer at a whopping $49! Hopefully when it shows up it actually really is the right part because thats dirt cheap.





Heres some more of the damage, nothing was smoked too bad yet, like I said the trans still worked fine when I yanked it. Of course the wimpy OD clutches were glazed.




The manual 1-2 band was burnt up

I gotta fix the TS on this camera I just took all those pic like 20 minutes ago.

Heres some of the new parts

Transtar O/h kit (no side cover gskt, sons a *****es)



clutches, bushings, steels, shift kit, bonded pistons, filter, forward band, Hi-energy 1-2 band, sonnax boost valve, sonnax TCC reg. apply valve, EPC, front sungear etc.



Heat treated 4th hub


New 15/16ths chain


Blue plate OD clutches



So thats the jist of it so far.

We have the special tools to do that but I have seen pics of people using zipties or hose clamps to do it. Get inventive, any thing to squeeze them down without wrecking them.

If your going to buy the tools then there is nothing to it, pick the old rings off, use the installer to put them on, grease the **** out of them, put the sizer over them without screwing one up, let it set far a while. Good to go. I havent built any FWD except for fords in a few months I dont even remember what rings have to be sized.

I believe theres a few 4t65E experts on here that are paying advertisers I dont think I can comment in a way that promotes my business without getting *****ed at

a few more pieces to this puzzle. I cant find a set of heads for cheap that arent cracked so I am STILL working on this project and it has definitely transferred to long term.

building the pump, with new vanes the ring and rotor still looked like brand new.




setting up the accumulator assembly with the shift kit springs and new seals.



shift kit springs in the accm. in the channel plate.


4th clutch piston and sprocket support assembly. New seal rings and lip seals.
installing the snap ring

done


original stock 2nd clutches.

upgraded aftermarket 2nds and new steels


complete with extra steel as per shift kit instructions, makes 1-2 shift way cleaner


stock clutch pack from the 3rd/input drum

aftermarket HD clutches and new steels

Wore out input clutch apply piston. If you build one of these you may as well order this part with the seal kit because your going to need it. I tore down 8 core input drums and they were all just like this.


apply pistons and retainer stack up

Installed



I took extra pics of the seal ring fitters we were talking about to give a better idea of how they work.

This is the expander, it goes on the shaft like that, lined up with a seal ring groove then you push the new seal ring over it.

This tool over the expander is just for pushing the rings down sqaure but they arent really all that picky you can just use your fingers.

Push this over them once your done and let it set for a while.



Threw everything back on the cart after that night. Still havent finished it yet. Like I said I dont have an engine for the car yet anyway so i dont really need it yet.
