I will admit the relearning process was not ultimately achieved, so this might be some of my concerns.
The trans worked great before and still performs well.
I am unsure if this is normal or if my trans is going out.
Hoping some of you could give me some of your thoughts.
- When accelerating slowly, the truck will "lunge" when shifting; sometimes, it shifts hard, and you feel like someone kicked the bumper.
- Accelerating from 50-75% throttle shifts quickly and smoothly.
- I understand shift flare and why, but it will flare, then shift, then act as if you are riding the clutch for a second or two before it engages fully.
- In tow haul, 4th gear will only hold for about 2 seconds then quickly shift to 5th, but 3rd gear will hold until 2400 rpm no matter how much throttle.
- While shifting down from 2nd to first, it waits until I almost stop, then shifts to 1st. This pushes the truck (not through the brakes, but it's annoying).
- Each shift is like described above, where it is not smooth; it either hits hard or feels like you are slipping the clutch if it was a manual, but the clutch popped, and the gear is too high (if that makes sense).
The trans just has not been smooth, and I have put several thousand miles since the modification.
I see average temps while driving or towing, respectively, and do not have any slip while pulling the camper, 15k.
I am just concerned I am losing the trans but hoping a relearning would be the first place to start.
It's always hard to explain what you feel and hear in your own vehicle, but I want a smooth-shifting trans again.
Thanks for any help or insight you can share.
