TR3650 / T45 Differences

the t-5. i was under the impression they were the same design, kinda like the sn-95 being on the fox platform. ha, the 3650 has it beat already, aside from the shifter linkage and hydraulic clutch on the s197 being different.

No, t-5 and t-45 are totally different. Only part that interchanges is the shifter. Everything else is different
 
Thanks to everyone's input. Mustang5L5, you nailed it.

The BEST way to find out what tranny it is, it's by mesuring the stock shifter:
3650 = 1.2" from base to pivot ball
T-5/T-45 = 1.5" from base to pivot ball

I got a T45.
