Question about 1999 Jeep Grand Cherokee
Jeep Laredo throwing these codes. p0743 p0753 p0748 Before replacing the transmission, I'd like to know if there are any other possible repairs i might try. Thanks
When diagnosing multiple fault codes it can be tricky figuring out whats going on for instance all three of the codes you have are an electrical nature and not mechanical faults in the transmission most likely they share a common power or ground circuit and have lost one or the other also if they do share any circuit and anyone of these are faulty it would generate the other codes. to do an accurate circuit check you should remove the transmission pan so you can check the terminals at the solenoids and switches on the valvebody because the problem could be in the "passthrough" connector

SOURCE: jeep codes location of unit
Got me a complete manual for 199 jeep factory model and found location of each individual unit in question. Manual gives u possible solution to each code and repair and or replace. As a mechanic myself testing, trouble shooting and repair was not that difficult. Shift solenoid was very difficult to get to. Located under the head lamp passenger side.
