Lockup 904 question

junkyardhero said

that is for a hydro unit, look back at the description and read the detailed notes.

instead of using a speed sensor and TPS, you're using a vacuum switch and a oil pressure switch to engage the LU solenoid.

obviously, you won't use that whole set up but you can accomplish it with some of those parts and a small switch. somebody on here also used a NOS solenoid to do the same with a 42 or 46 RH, same idea.

I beg to differ with you. All the transmissions you referred to have an electrical solenoid inside of the trans, that controls the fluid for the lockup. They have a electrical connector external to the trans. The 904 hydraulic lock ups do not use a electrical solenoid, and do not have a electrical connecter on the trans for lockup operation. The only electrical connector is for neutral safety and backup lights.
I was wondering if it is possible to convert the non electrical LU to electrical. That would make it easy to control manually.
