I have a 07 2500 6.7 with a delete kit and chip that were installed about a yr and in the last month started having problems with slipping tranny. So we decided the tranny needed to be replaced after researching. Just installed a rebuilt Jasper 68RFE after finished install test drove it shifted beautifully then parked it for about 30 and left the shop then started having problems shifting. Tranny temp was up to 170 and threw a P0732 code. Any ideas?
