My 1997 jimmy automatic transmission works great other than the drive gear. slow take off in drive, its like a standard taking off in 3rd until i hit about 50 km/h.then its fine. also overdrive doesnt work at hwy speeds. transmission works fine if i manual shift 1-2-drive. fresh filter and fluid. all other gears work great. i scanned it and the following codes come up i was just wondering where i should start fixing :) order in which scantool Canobd2 3130 lists
1-torque converter clutch solenoid circuit p0740
2-mass or volume air flow circut low input p0102
3-shift solenoid a electrical p0753
4- shift solenoid b electrical p0758
5-shift/timing solenoid p0785
6-atf pressure manual valve position switch malfunction p1810
7-tcc pwm solenoid circuit p1860
8-transmission fluid temperature sensor a circut high input
Not sure if this is the answer yet but i have the same problem with the same codes i work at an auto parts store and a few of the techs that are customers have lead me in the direction of changing the ignition switch, i am doing it today will let you know if it solves the problem

sorry forgot to put on air filter and plug in sensors so trouble codes 2 no longer exists
found my problem all it was that my power plug on my transmission got unplugged somehow on the passenger side of transmission, had to change plug but now everything works great.
transmission will not shift out of drive at a stand still, but once you get up to about 50 mph. it shifts perfect. what will cause this
