I’ve read through all the common trans problems and I feel I’m having issue number 2 but I want to be sure before I throw money I dont have to fix it.
- Truck won’t shift until you let off the accelerator 1-2 gear, have to be going at least 20mph for it to shift
- If you accelerate too hard in 2nd gear, truck dumps back into 1st (tried do this to me at 40mph once) so you have to creep gradually building up to 3rd gear
- Truck puts up more of a fight to shift to 2nd when truck is cold or when trying to upshift on an incline
- I’ve noticed truck is very slightly shuddery low in 2nd gear
I’ve hooked to a scanner back when I first got the truck a year ago as it’s done it since I’ve owned it and transmission pulled no trouble codes. I’ve drove it the same way since then, another 16k miles (157k on it currently) and issue hasn’t changed any.
Reading other write-ups in another forum with someone with similar 4L60E problems they found their issue to be their TPS but the difference wih theirs I took it as is they had to let off to shift any gear, not just 1-2. Is it a safe bet a TPS would fix my problem or should I look in elsewhere?
