Jeep only shifts in high RPMs - continued
I just purchased a 1999 Jeep Cherokee 2WD, 4.0 L and 4 speed automatic transmissions. Currently the transmission only moves the vehicle in reverse at high RPMs. Also, when driving forward, it requires high RPMs to shift from one gear to another. Previous owner did not maintain the vehicle well.
Update to my original post above:
Transmission fluid looks good and does not smell burnt.
I checked the codes in the OBD-II and I have a P0700 code. The mechanic said I need a new Transmission Control Module (TCM).
I removed the TCM and I will check on prices tomorrow.
I drove the Jeep and I do have reverse. When I put the transmission in "D", I realized that it takes high RPMs to make the vehicle move because the transmission is essentially in its highest gear. When I put the transmission in "1-2", it takes a bit less power to make the vehicle move. Also, the vehicle will shift manually from "1-2" to "3" and to "D". It also downshifts a bit rough from "D" to "3" and to "1-2".
Before I purchase a new TCM, can someone tell me if the above symptoms are in line with a TCM going bad.
Is there a way to test the TCM?
What else could it be?
Thank you all in advance,
