Need advice tuners. Just changed a SR20 CVT transmission and now after running the vehicle runs for about 15 mins it just gears down to first gear and sticks there. Already changed the speed sensors and the electric solenoid and still no change. Did a diagnostics today and not getting any reading from the input and output speed sensors but everytime it cools down and starts again it runs good for a 15 mins and then the problem starts again.
Any advice will be greatly appreciated.
