Well, I ran into a problem with my swap. I'm converting a 95 Sonoma 4x4 4.3L TBI with a 4L60e tranny to a 400 small block with a carb. My truck has push button 4x4 engage. Does that mean that the transfer case needs the computer? I was hoping to ditch my computer. Does that also mean that there is NO way I can convert my tranny to shift mechanically instead of electronically? (I mean without purchasing a stand alone unit to control the tranny). My knowledge of transmissions is very limited, but I read up on a way to do this. A guy on some other forums says he did it, using a 4L60e. I'm wondering if it can be done with my tranny as well. Please take a look at the method....

Hey,
All the other posts talk about buying just a hook up for it. I did all mine, by myself. Took less that 30 min, and it locks up to my plesure(well, its automatic lock up, but you can easily wire it to a switch). A quick overview is you use a single-pin connecter from a TH 400(the piece that screws into the tranny, the 700R4 has a 4 pin), cut 3 wires in the tranny pan, install a
brake cancel switch, and in my case install a low vacuum switch for automatic lockup, or in your case, a manual switch. If you want the whole story on how i did it, just e-mail me at fathead_03@hotmail.com

have fun, i had a FI engine, made it carb, have a 4L60E tranny (electronic lockup torque converter 700R4). We just cut i think 3 wires, hooked one back up, changed the 4 pin from 700r4 to a single pin from a th400 tranny, installed a low vacuum switch, and a brake cancel switch, and it works like a charm. IM me if you would like to know the exact wires, and parts you need.
I guess my question is, can I do this....and keep using my 4l60e tranny, and still use the same transfer case, and retain my push button 4x4 engage???
