Hello everyone, I have a bit of a doozy.
So a few weeks ago, I started having an issue while driving down the highway.
The truck started gaining RPM, without gaining speed. So I pulled over, waited two or three minutes, started it back up and it drove fine.
This issue happened just about every time I would do 10-15 miles on the highway.
The fun issue though, started two weeks ago.
It developed a knocking sound, barely had any power, and didn’t want to shift into the next gear. I checked it all over, and from my ear, it sounded like the knocking was coming from the bell housing/flex plate area. Inspected the flex plate bolts, no issues seen there. Pulled codes, and had a code for transmission solenoid. Replaced the solenoid, and issue remains.
It doesn’t want to shift into the next gear up, unless I let off the gas a bit.
I took it to a transmission shop, and they heard the noise and didn’t even inspect it. Would I be wrong to assume it could be the trans?
Checked compression on all the cylinders, and while low (I’m also using a s*** harbor freight compression tester) all within 20 psi of each other. Range from 120-140.
All the injectors are firing evenly.
Any ideas?
I’m not convinced it’s not something in the transmission.
