How do I reset my 4T65E transmission?
all you do is drive it, the trans will re learn as you drive. every time you take the battery off long enough for the pcm to clear and reset, its all relearning. and the neg cable will be off for longer then 30 minutes while they swap the tranny out. so its all good.

What is the difference between 4T60E and 4T65E?
The 4t65e is inherently stronger than a 4t60e; but lack of auxiliary cooler, cheap seals without enough lip, poor PCS design/placement, and non-hardened parts where they are needed all contribute to early failures of these units. All of this is correctable with aftermarket parts (upgrades, shift kits, etc.)
Is the 4T65E transmission a good transmission?
The 4T65E is for the most part a fairly reliable transmission. It is the successor to the 4T60E. Variations of this transmission have been common since the 1980’s. By the 2000’s most of the kinks were worked out. But, like everything else, it’ll break and wear out with mileage and time.
