I have an 84 cutlass supreme brougham. I already swapped in a 5.3L truck LS thinking i had a Th350 like typical specs showed, but i guess having a canadian sold or built model i seem to have the weaker (M31) TRANSMISSION,AUTOMATIC 3-SPEED(THM250C)
Not sure if i just got lucky but it bolted right up and has been driving flawlessly for 2 months now.
Anyways i cant really find online if theres any difference between the 3 forward gear ratios or are they exactly the same?
whats all different ? someone mentioned 1 less clutch disk and band?.....
if i blow this transmission and want overdrive is it better to go with a 4L80 even though i would have to re-add the wiring?
or will a 2004R also bolt up to a 2002 5.3 L Ls?
is the 2004R same length as th350 and save me a new driveshaft by chance?
