I need to know which transmission i have? Want to buy a thrasher shift kit but i dont know what transmission i have in my car.
Plain 93 bonnieville my guess is the SE but there is no markings.

4T60E. Plain SE. Thrasher doesn't make a kit for it.

Man that sucks, just cause are cars aren't superchared SSEi'*. With different tranny'*. That'* a drawback.

I have the 4T60E-HD in an SSEi. No shift kit for it, either. My Jet chip does it for me.

Well the SE'* that year had BETTER Final Drive Ratios ANYWAY! The SE have 3.06R while, the SSEi'* have 2.97R! Therefore the SE'* were faster off the line than the SSEi'*! This only applies to 4T60-E'* though!

i still have the orginal tranny with the 3.06..plus the one with 2.69. sitting in my shop...now have 3.79 installed.and there is a shiftkit for these trannys` contact Hector The Sunny...... he knows where to send you

turtle, how fast have you had your car going?

Whats the gearing for my 94 SSE then?

1994 > M13 > 3.06R / 2.97R / 2.84R

:? um i`m not allowed to sat how fast i went when i had the 2.69 tranny in.( 155mph ) cuz i`d get into trouble with the 3.79 i`ve only touched the 135mph once backed ogg no room left.....but 0-60 @ 5.5sec.....spinning the shoes....not after the topend trophy anymore...want good handling and quick.....not fastest..haven`t tried the new setup on NOZZZ yet have to wait for a good sunny day
