help on tranny

95cobra · 07-21-2008, 09:30 PM

when i bought this car and put it on the lift i found out the tranny had been swapped to a tremec.

1st-question is how can i tell what model it is. i can see tremec stamped on the side but i didn't see any numbers or anything stating the model.

2nd- question is i need a shifter for it. any suggestions from experiance. i hardly ever miss a gear like it is but everyone tells me i need a short throw shifter.

i haven't been dealing with mustangs long i was big into drag racing chevy s10s

Tremec now owns Borg Warner. Most newer T-5's will have the "Tremec" name on it some place. It's likely just the stock T-5 that came in the car.

If you have a digital camera, snap a few pics of it and maybe we can confirm that.

A short shifter will make shifting that much easier and quicker. Go ahead and get one; you more than likely won't regret it. I personally like the Steeda Tri-ax shifter... others prefer the Pro-5.0.

on top the tranny it looks like it has two plates that look like you might could move the shifter. i know you prob cant but they have 4 bolts just like where the shifter sits.

also the trans mount sits in a different place from where the stock once was. looks like about an inch diff. also the rear seal does not line up where the stock one was meaning. i can tell where one seal was rubbing and now the tranny thats in it now is rubbing diff spot like tranny is shorter.

guy i bought it from said he paid 2800 (600 labor) for a new tranny swap. i didnt know of any other tranny besides t-5 so i didnt ask question now i cant get in touch with him

hmm. might actually be a 3550. What's the bellhousing look like? Get some pics up and we'll decipher it for ya! Hope it is a 3550...that's a really nice trans.

Yep, it's probably a TKO. You can tell the series by the pattern of the shifter bolt holes; both transmissios use 6 bolts, but the newer TKO II (500/600) have them the same distance apart. On the older TKO's (3550), the front two bolts are closer together than the back four.

If it still retains the stock driveshaft and original driveshaft yoke then it is more than likely a tremec 3550 or a newer tko 500.

Also from what you are describing.You need to install a driveshaft spacer too.I had an issue on my old 94 where the driveshaft yoke wasn't engaged far enough into the trans and caused a few problems.

UPR makes a nice driveshaft spacer that takes about 10 minutes to install.

Did they change the 500's to a 28-spline output recently?

When I bought mine two years ago, the TKO 500 had a 31-spline output just like the 600 did.

you could order the 500 either way at one time.But it had to be ordered that way.
