Ever since I've owned my truck (3 years), I've noticed it shifts hard (basically drops it into gear) from 1st to 2nd, but only when very little throttle is applied. It will do it consistently when idling in traffic, cruising through parking lots, etc. Give it slightly more throttle, and it's fine. Otherwise, the tranny shifts great through all of the gears, even at WOT.
The truck has 120k. The tranny has been regularly serviced every 25k or so. No burnt fluid, no shavings in the pan. The only other thing it's done is slipped in first gear from a dead stop a handful of times, but I think I fixed that with a bottle of Lucas (crud in the valve body?).
I did a lot of research, and everything led me back to the electronic control aspect of it. I've already tried cleaning the MAF (no change) and next is the TPS. However, it seems that the TPS is actually part of the throttle body on the 5.3l engine.
My question is, is it possible to replace just the TPS without replacing the whole f*cking throttle body? I've seen kits online, but it looks like I would have to drill out rivits and then bolt it back together.
