So i have a 1998 Subaru conversion from gears to an forester version 6 automatic. I bought the car that way and it ran very well for 3 yrs. changed the head and block last weekend, used the same transmission - thought the converter did give a little problem to go in - the head of the shaft had widened a bit. anyways .. it's all fixed in, started ,, gone for a test run & the gear is stuck in 3. it's not changing. and the power light keeps blinking. need some help !
