Hello all.
Wondering if anyone has come across this particular issue and found a resolution. Ive found some threads searching that are similar but it seemed no resolution was found.
What happens is that the Transmission when cold will seem to stick in 1st gear. The way I like to describe it is like when you put the shifter in the 1-2 position and it takes almost redline to get it to shift to 2. This same thing appears to occur when in Drive. Interestingly especially on a cold morning when starting the Jeep the transmission will make a whining noise.
After driving the Jeep through a few stops and it exhibiting the problem it will go away and start shifting fine. I thought it may be a pump issue, but part of my troubleshooting has included a flush of the transmission using the return line disconnect procedure and fluid was flowing out the return just fine...
Any ideas on this one? Could this possibly be a NSS issue even though there are no issues with reverse or backup lights? What about solenoids?
I would hate to go through the effort of rebuilding a replacement when its something I'm overlooking. And just an FYI its not the TPS as that has been replaced with multiple known good ones. Grounds have all been gone through multiple times as well.
Thanks for any insight you may have.
