Re: Transmission won't engage
Dorman oil pan with a drain (way cleaner and easier), Sonnax Line Pressure Booster, Transgo Shift Kit, and Superchips Advanced Transmission Tuning Application (ATT) set up with my custom shift schedules and torque management settings. The transmission is now day and night better than when stock. Shifts are very firm (very little slippage), both light and full throttle and upshifts/downshifts are set exactly like I want them, with no lugging and smooth downshifts with just he slightest addition of throttle.
Best/easiest place to start is with the Sonnax Booster, as it can be done externally (plug and play) and it's not overly difficult to get to. By itself, it won't make much difference at light throttle, but you'll notice it at advanced throttle settings. The Transgo requires dropping the oil pan (good time to put on one with a drain plug) and removing the valve body. It's an easy upgrade, but a little messy. This firms things up a bit, without doing anything else. The ATT App., programmed correctly, with tie everything together and make it about as good as it can get without a performance rebuild.
