hi i recently lost 1st gear and overdrive, my transmission has gone into failsafe mode and i can not seem to figure out the problem. the fuse keeps blowing with the transmission plugged in. i have replaced the a & b shift solenoids, the TCC lockup solenoid and the ignition switch. the fuse doesnt blow when the transmission is unplugged so i beleive the problem is in the transmission. when i replaced the 1-2 shift solenoid the 1-2 shift valve pushed the solenoid out as soon as i removed the clip that was holding it in place. when i put the new solenoid in place i had to hold it to stop it from popping out untill i put in the clip. i also inspected the wiring harness when i was in there and did not see any issues with it. i am not sure what i should try next and any help would be greatly appreciated, thanks.
