That's what did it. I am 100% sure now. Look at this information:
92-00 SC300
6 cyl, AT (4.27 ratio)
92-96 MKIV Supra:
w/o turbo; (4.27 ratio)
w/turbo, AT (3.769 ratio) Limited Slip
97-98 MKIV Supra:
w/o turbo; (4.08 ratio)
w/turbo, AT (3.769 ratio)

I think you should be fine as long as you don't make any high speed runs. Guess I did a few too many. I'm looking for a used automatic Supra TT diff now. I hope I find one with LSD.

Chris,
Did you have the sub-throttle TPS working or did you eliminate it with the TRAC block off plates? Also, did your tranny just die all of a sudden or were there any symptoms before it happened(reving really high, having trouble shifting to a different gear, etc.) Good luck finding another used auto tt tranny...
thanks
William

Chris,
The sub throttle TPS sensor is located on the throttle body. If you looked inside your throttle body, there are 2 throttle body plates. The first one is the sub-throttle body plate(also called the TRAC plate) and the second one is the actual throttle body plate. A lot of people on supraforums take out the sub-throttle plate to increase air flow and then take out the sub-throttle TPS and TRAC sensor and cover it with the cover plates.

Also, when was the last time you changed your transmission fluid? If you've changed it recently, what was the color of it?

Hows your transmission holding up. Looks like I burned mine up with the low ratio diff.

I have Keans Th400 kit and love it BTW. -Brett

Chris,
Sorry to hear that...More money and time down the drain. As for my transmission, I haven't had any problems with it, thank god... Stock differential too....I have one extra tranny cooler and thats it... Do you know if your transmission lines are close to the downpipe? I remember that mine were kinda close so I wrapped them with insulating material. Other than that, I don't know why you are burning up trannys...If you need anything else, just let me know...
