I am having issues with my tt transmission. I did recently install a hks alc & probably had less than 100 miles with it installed. I took it out & a few days later on the way to work I lost drive & over drive. I've drained the pan twice & topped off with fresh fluid since I bought the car 6 months ago. It wasn't very dirty to begin with, just for piece of mind. 1,2, & R are all perfect but when it shifts to drive it's like going to neutral. When I ran the diagnostics I'm getting revolution sensor. Nissan no longer offers them for the tt transmission & I'm not even sure it's bad. I disconnected & cleaned the connectors under the hood but made no difference. I disconnected the harness from the tcu & reconnected which also made no difference. Is there anything I am overlooking? The revolution sensor could definitely be bad, it just never gave any problems until the other day. I don't believe it's mechanical but I'm no transmission expert either. Any imput is appreciated.
