Last Friday we had some bad storms down here in FL and that night I went threw a decent size puddle i did not think it was too bad..but soon after my SES light came on and it was in limp mode the tranny was stuck in 4th. I pulled over and hooked up my uprev cable and pulled the codes and 1st it was 1759 and then 1759 for the Front Brake Solenoid Valve, Control Valve assembly Unit. I have searched on the boards and seen alot of people have had to replace the TCU which is 800+ I let the truck set for a few days and then I cleared the codes and then drove down the road and the SES came back on and its stuck in 4th agin..also sometimes when i start the truck the AT CHECK light will flash 3 or 4 times and then go off. And the BRAKE SLIP ABS light will blink on and off at the same time... do you think i shorted something or did the TCU just happen to go out when i hit the water is there anything elese i should check...would the TCU going out cause the BRAKE,SLIP,ABS lights to flash on and off...I checked all the fluids looked ok..now the truck does have 140k miles..any help or suggestions would be great...Thanks:bangit:
