I have been having problems with teh tranny for a long time.
It shofts hard from 1st to 2nd. I did the flush and fill/and filter as per the service bulletin. It took about 1 week after to straighten out the problem. It is now 6 months later and it is doing it again.
I took it to a transmission shop, and it has code # 748
pressure control seliniod , electrical.
I know that the flush and fill was in the service bulletin, then if that wsnt the cause, it said to rebuild the valve body.
Any insights ?
