hey guys i'm new on here, but i need help with my ram, i had it in 4 low the other day in a snow covered field maybe 6 inch's deep i was keeping the rpm's steady between 1500-2000 rpm's truck is warm and all of a sudden there was a loud thud, truck didn't die or loose power, still remained in gear, so i put it in 2h and truck only stays in first gear, i tried to put in m2 still nothing, so i shut it off checked for leaks and everything, checked trans level it was a little low but not majorly, was red, minor debris, magnet was clean, i checked the governor solenoid it seemed fine, not clogged, all wires looked good. however i did find a bolt, and appears to be a small c clip in trans pan, have no clue whats wrong, should i re-adjust my 1-2 band? Is it broke. speedo was not hooked up prior to this happening, hooked up a scanner and these are the codes P0500, P0108, P0132, P0135, P0141, P0138, P1391, P0172. I could really use some help fast!

 

P0500 No Vehicle Speed Sens Signal

P0108 Map Sens Voltage Too Hi

P0132 1/1 O2S Shorted To Voltage

P0135 1/1 O2S Heater Failure

P0141 1/2 02 Sens Relay

P0138 1/2 O2S Shorted To Voltage

P0172 1/1 Fuel Sys Rich

P1391 Interm Loss of CMP or CKP

Was the lite on before the problems started?

No VSS will give you shifting problems. If the PCM doesn't know how fast you are going, it doesn't know it should shift.....

The rest pretty much relate to O2 sensor issues. I would almost suspect a wiring harness got pinched somewhere.

 

yes light was on prior, im pretty sure it has the wrong year diff on cause the speed sensor doesnt match up. truck was driving and shifting fine prior

 

Should be able to just pick up the correct sensor for your year, and drop it right in. 98 and up get vehicle speed info from that sensor.

Clear all the codes, and see which ones come back.

 

Ive tried hooking that sensor up a long time ago, still didn't show speed, switched the polarity, still would not show not show speed. Could that sensor be shot? So it was running and driving with that sensor out before. but i will clear codes now, does engine have to be running to check or just switched to on position?
