I own a 91 RRC County and the trans had been acting up the past 6 months. It finally went out and stranded me for the millionth time... I finally got around to swapping the trans out with a used trans that has 90k on it. It was the best/most affordable i could find that could be shipped. So i had the trans shop install it and of course it is not shifting properly and the shop wants X more thousand dollars to look into it. Before i do that or tow it to Land Rover Cincinnati i was wondering if it could be something like the ECU needing to be reset or the shift linkage altered. The rover goes into gear now but it will not shift into 2nd until it is WAY up around 4,000 RPM, so i haven't driven it since trying the first time. I guess my question is are there any checks i can do before i open up the wallet again big time? I am somewhat mechanically inclined and have a friend that is a mechanic and available to help. Where should i start and any guidance would be appreciated. Sorry in advance!
