Go to **Edited Out by Moderator** and check shift solinoid replacement threads. You ain't the first with a shift problem. It probably is the solinoids.

Sorry but I would highly recommend not referring AF members to another automotive forum. Your post has been edited.

ok...is there anyway you eould be able to private message me that site?

Yes, he may send you a PM or regular email.

I had a very similar problem .... try searching for my threads. A new ECU fixed all the issues. If the shifting problem starts then goes away .... imo ... solenoids don't usually heal themselves.

any other opinions??????? any will be greatly appreciated! thx
