Possible trans upgrade

[Vetruck]

I was actually looking at a 3.67 rear diff out of a c240 since the trans swap is the same 1-4 gear ratios and is just adding an OD gear past 1:1.

THis computer stuff sounds like a headache. Remo, when you say swap parts, are you saying the linkage and wiring harness are different also? I know GM stuff like the back of my hands, what marries up to what, what and where to get trans computers for the 4l60e etc. I can not pu the GM 6 speed (6l80e) into my truck without an LS motor swap due to different bolt patterns. Sounding like this little car would be a much bigger headache. Just a simple rebuilt trans for about 1500 is starting to sound like a sensible thing for a car the misses drives 99% of the time.

ps- my current rear end ratio is already 3.37-(EDIT- WRONG- I apologize, I do have 3.07's. The c280's my year had 2.87's)
