***code ?'s***

i recently rode in a customers truck and it threw somecodes. he has the banks 6 gun with just exhaust and its having tranny shifting problems. The truck is a 02 with 120,000miles. the codes its throwing are:

P0700
P0746

can anyone help?

What setting has he been running the Banks on? The p0700 means that the TCM has detected a fault, and the SES light needs to be illuminated. The p0746 sets when a clutch is slipping. The actual description of the code is Trim solenoid A stuck on/off. More than likely he has run the banks pretty high, and the trans isn't liking it:doh: Just my .02
