So i am getting tired of my transmission’s inconsistent shifting between temperature changers along with other issues. Like the throttle cable being tight enough to raise the line pressure like i like but then having issues with shifts hanging or random harsh kickdowns when it shouldn’t be. Etc. There’s a lot to be desired.
So i like DIY type projects where i get to use some creativity as well as really get to know a system. So i am thinking about converting my 47RH over to pretty much full electric control. i know a few people will be like, why not just swap to a 47re or 48re, and better yet; buy a standalone controller from a vendor. WELL. I already have this transmission and the options available leave much to be desired. My biggest complaint is the lack of TCC lock and unlock control. Which i will share my ideas as this progresses. My other issue is that with controlling the shift points by the electronic governor pressure regulator, it can still be finicky with temperature changes and lacks direct line pressure and throttle pressure control.
So my thought is (simply put), adapt some OE style dump solenoid valves (like what is used for the OD and TCC) to the governor plug side of the 1-2 and 2-3 shift valves. Then use a GM pressure solenoid valve to control line pressure completely independently. Originally i was going to build an Arduino to control this, but then i found that MegaSquirt has actually came out with a MicroTcu board that is TunerStudio compatible and should be able to do everything i want for a decent price.
Sorry for the long intro, but what are your initial thoughts?
