throttle body to CPI
 

I bought a '91 S-10 with a bad 4.3. I have a good '93 4.3 with CPI, wiring and ECU, out of a Blazer I had. What do I need to do, to use it, with my 700r4 tranny, instead of the 4l60e tranny it had.

What about the fuel pump, do I need to change it also?

Thanks, Pat

fuel pump would definitely need to be changed, and other things. I am sure others will chime in.

Has anyone have an idea, as what has to be done, for the 700r4 to be used?

bolt it up,get a tv cable bracket from one that had a 700r4. wire up the tcc lockup switch to the brake pedal so when you touch the brakes the torque convertor unlocks.


yes,pump has to be changed.
