I have a 91 accord DX with auto tranny. The reverse gear blew out, so i did a tranny swap with the same type (with low milage). When i got done, i went to drive it and it wont stay in gear. It would drive fine for awhile, then it just wouldnt go anywhere. I did 3-4 fluid flushes (magnit had a few shavings, but nothing bad) Still does the same thing. Idk what it goin on, maybe the shift solinoids? any info would help.

Note: "S" light goes on and off as it should, so i dont think its the TCU.

Please help!

Thanks Will.
