    1987 535i e28 transmission and diagnostics

    I have an E28 BMW 87 535i M20... Now I don't know the transmission models 100% but the original trans had the E/S/321 selector switch. My 4hp22 7pin transmission went out and I replaced it with an 4hp22 8pin transmission from a 92 735i and the 7pin connected perfectly with the 8pin connector and is stuck in 3rd gear(limp mode)? The BMW parts warehouse I bought it from said there were no trouble codes from the transmission when it was taken out. And apparently the 15pin connector under the hood is not a diagnostic connection? Can anyone help? Is there a 15pin to 20pin conversion I can do for future diagnostics?

    Early model 87 535i

    I had a post on here before, and it got deleted I guess? But I have an early model of 87 535i before the diagnostics were added... Well I was having transmission issues and swapped out for another 4hp22 transmission. The original had the 7 or 8 pin connector amd the new trans came out of a 92 735 and had a 9 pin connector... Not 100% sure on how many pins there are but it still fit with my connector... The transmission is stuck in 3rd gear and the orange gear with (!) In it is on... Any advoce would be of great help!!!
