Hello, im a newbie posting here.. it has questions too, so i don't know i this thread goes here, but nobody is perferct O0 im bullitt66 form svtperformance and this is my first post lol..



I didn't found a lot of info for the t-45, but my trans broke someting, i was able to put the shifter in 1rst, and the trans was in 1rst to, changed the shifter to 2nd or neutral and the trans would still be in 1rs, So i took out the trans from the car myself and opened it with my friends, i found it was the gear shift plate that broke, what was the reason? :shrug: someone here may know i hope, now im looking to upgrade it because i already disassembled it all, do you guys know if any hanlon kit cames with that shifter plate? maybe red98cobrastang knows..
what kit should i get now so it can build an upgraded t-45 tha i won't have to worry for some time?.. i know ill need steel shift forks, what more would you recomend??

the good thing is i did it myself with my friends and learned as always, here are the pics of the progress..

First we took out the bolts of the tailhousing, you'll need to punch a pin that sits where the shifter goes, so you can remove the tailhousing, then it should look like this..

Then remove the bellhousing and you can see the shiter plate broke if you pay attention or if you know the t-45.. i should be like two little "U", but since one broke, thats why i was able to move the shifter, but not the shift forks..

This is the piece that broke, i found someone on stangnet posted that too, but the only reply was "check out d&dmotorsports :(

Starting from the back, we took the bushing out, and the c-clips we found on the road

Tought that was the problem, Japan Bearings :pepper:

Since we don't have all the tools, we like to improve, those parts were not born there.. lol

Now, we go to the front..

IMG_0283.jpg


As always, the last screw was a PITA, aluminum + a steel screw gets real tight as time passes..

We used a torx and we broke it, then we used an air gun, and broke the torx before the screw could move.. it was about 250lb/ft (like 3-4 hondas) and it didn't move. So i learend that if you heat the aluminum, and then use a little wd-40 on the screw, it won't be tight anymore.. it was real cool to see this..

Then, would need a press to take this gear out, but a little hammer did the work..

Wow I wish I had seen this sooner! I already tore apart the T45 in the 97 GT I used to have. Lets just say a new set of synchros, bearings and seals makes one heck of a difference.

Nice writeup!!!

yeah, once you remove the transmission from the car, the bell housing is easy as pie to remove. just unbolt it from the rest of the case via the bolts that you have to access from the inside of the bellhousing. you use a screw driver to seperate it from the rest of the case (it has RTV from the factory). the input shaft just comes off, but becareful of the bearing races and shims that may pop off. they go on the bellhousing.

t45's are easy to work on!

Just 2 special tools needed 1-a set of eaton style lock ring plyers. Can be picked up at O'reillys
2- a press to get the main cluster out.

here are a couple of tranny and parts pics of what I have made to beef up the t45's

The fork you see is a CNC Billet Aircraft quality T-6061(LOL) 3-4 gear fork and is prone to breaking from 2 reasons. 1- junky shifters over throwing and 2- the fork is very weak. Also the shift fork selector links that rest in the forks have a ton of stress cracks. Relieving those cracks will improve life.
All in all the t45's are a good tranny and do hold up to some HP. There are a couple of more tricks to improving it's life, It's the shifting assy. that sucks.

so you think i could rebuild one myself? Just wondering. B/C i'm going to keep the auto but i got a t45 that is shaving the forks so i was going to rebuild it and sell it or something. Or does anyone want one to rebuild? I'll sell it for what i got in it.

Not much to improve on those, but relieving the stress. It would be very costly to make them compared to just improving what you have.

It is simple to do. Polishing the whole link and radius the corners. Any time a sharp edge or corner is in steel, stress is there. Radius relieve!
