1989 TPI with a 4L60E, possible???

Post by rlsllc »

As stated, is it possible to run a TPI with a 4L60E. I'm interested in doing so, the trans is a 1994, but I may be interested in using a '99 trans. I know the signals are different due to PWM solonoids and such.

Thanks!

Did you ever find out about this?
I've got an 85 TPI and was wondering the same thing. I've looked at the wiring diagrams for it, and I get the feeling it would require a lot of modification because the CPU from the TPI doesn't have pinouts for the transmission signals.
Perhaps it would work with a stand alone fuel injection system?
