Tranny Questions

I went with one of the last Tremec 3550s before they switched to the 500 and 600 transmissions. Here's a link to a recent thread about the 600, which is what I would recommend. http://forums.stangnet.com/showthread.php?t=625518

if you don't want to deal with the different dimensions of the tremec, a g-force t-5 might be the way to go, however, many more guys opt for the tremec because it is proven to kick a$$ where there isnt much experience with the g-force trannys

i wish i could help ya with all fo the differences... i dont know myself, but ill say that its everything you just said, and maybe more. theres so many guys on here that can help you in that department, use a search on tremec swaps and tremec trans and i bet you'll find all the info you'll need if no one chimes in here

Driveshaft spacer, shifter, 26spline clutch disc

The TKO500/600 comes with a shifter. Kinda notchy for my taste though.

Everything you may need:

Foxbody Clutch Fork
Tremec Bellhousing
New clutch for 26 spline (if you get the 600 or upgraded 500)
New Motorcraft T/O bearing if using a SPEC clutch (spec's throwout's are throwaways).
3 quarts of GM Syncromesh fluid
31-spline d/s yoke
3/8 driveshaft spacer kit w/longer bolts (steeda)
you may need to elongate the holes in the crossmember slightly to fit the shorter tranny. Some have had to flip the crossmember to solve vibration issues, some haven't.
a 1/4" spacer to go between the motor mount and crossmember, or a PHP crossmember adapter...

things recommended:
New front U-joint as you will have to pound the old one out.
If you don't already have an aluminum D/S, I'd recommend going with one for a newer car, the T-45 had a 31-spline output already IIRC, so you absolutely won't have U-joint or balance issues.

BTW I'd recommend going with the 600. I didn't, but I got an upgraded 500 with the 26-spline input shaft. A 600 would have been like 14 dollars more expensive, so I'm kicking myself there....

Oops, my bad. I meant tranny mount not motor mount....

Not to ad plug or anything, but I bought mine from CFM and the service was outstanding. It was pretty much a one-stop shopping center (already had a bell though) and they shipped everything free inside the tranny box, except the clutch which came straight from Spec.
