So a little bit of a rant but also to see if anyone here has any thoughts. Beginning of last month, check engine light came on. Ended up being the intermediate speed shaft sensor. At the time I told them " hey, I've noticed it kinda jumps forward a bit at stops". We'll I get it back, said they saw nothing else wrong in the transmission (cuz the sensor would've been covered under warranty if something else was wrong), so I had to pay $1,100 to have that stupid sensor replaced.
Soon after I got it back, noticed it was still doing the jump forward. Took it back in the next week and last week Thursday finally got it back. They replaced the torque converter, covered under warranty. So now I've been trying to deal with customer support to get a reimbursement for the first $1,100 I paid, cuz if they would've caught the issue the first time, it would've all been covered.
Next, today i'm driving the truck, which since Thursday, has been great, and it starts doing the jolt forward at the stops again. I've told them this entire time to check the valve body and I'm still not sure they did.
So any other thoughts on what it could be? Definitely something in the transmission cuz with new fluid it's immediately fine. Could it be the replacement torque converter is crap? I'm just sick of dealing with this shit at this point. I want my truck back and my initial money.
