I was wondering if anybody has done a 4L60E (electronic) transmission swap into a car with a carburetor.

I was considering getting a 4L60E tranny, LT1 PCM and harness, and then install the necessary sensors for the PCM to control the tranny (MAP sensor, TPS sensor, VSS sensor, maybe coolant sensor).

Currently I have a carbed ZZ4 engine with a 700R4 that shifts like crap; I want to replace it with a tranny that can be programmed to shift anywhere I want, instead of ***ing with that TV cable.

If this works I think the biggest challenges would be rigging up the TPS sensor to the carb and tuning the tranny. The car is a 92 so it originally had EFI and has a lot of the old sensors already... just a matter of running the wires.

Anyway just wondering if anybody has attempted this and what your successes and failures were.

Thanks.

 

canyou just get the tci controller for the trans ?

 

Yeah, that's the way to go. The programmer will allow you to program the trans with a laptp to do whatever you want. You can adjust line pressure, shift points, shift firmness, ect. I think they make them for the 4L60E. I know they are available for the 4L80E. The 4L80E also has the option of using a stand alone PCM from a Diesel truck that's been reprogrammed. They never put a Diesel in front of a 4L60E though. It would be like pulling the pin on a handgrenade and wrapping the lever with a rubber band. Eventually that rubber band is going to fail and the grenade is going to explode!

 

thats what i have on my car
same controller for 4l60 & 4l80
my car is fuel injected
but the carb shouldn't matter
