I just put a automatic sr20det in my s13 I've got all most every thing working but when shifting 1,2,D my car shifts from 1st to 2nd but doesn't shift to drive it will stay in 2nd but rpm's will drop to idel I have to stop and put it in R then back to drive and it will work fine.also when I turn the overdrive off and let off the gas the rpm's will drop to idel but otherwise the OD. works fine. I realy need the sr A/T controller wiring pinout or some good advice.

so I hope someone can help me with this problem.
