Tranny shifting late, P1756 code

From : huff

Q: 2001 ram qc 1500 felt like its either slipping a bit in first or just very delayed shifting to 2nd. i get a p1756 govenor pressure error code. digging around on the internet leads me to believe this is somewhat of a common problem. anyone have an idea of what i can expect to have a shop replace the solenoid and/or sensor that would cause this error does driving it as i have for a couple days induce any damage .

2001 ram qc 1500 felt like its either slipping a bit in first or just very delayed shifting to 2nd. i get a p1756 govenor pressure error code. digging around on the internet leads me to believe this is somewhat of a common problem. anyone have an idea of what i can expect to have a shop replace the solenoid and/or sensor that would cause this error does driving it as i have for a couple days induce any damage i would take it to a dealer to find the true code. i recently had 3 codes come up on my truck. i used the autozone code read and it came up with map sensor. deleted the code and went abotu my way and more codes came up. used the 3 cycle on and off and the p1756 came up along with p1693. i finally took it to the dealer. i told them how i came up with those codes. the service manager said the autozone machine is generic and not reliable. for the cycle start switch on and off said that is no longer worth a crap and not usable since the 90s. turns out he seemed to be right. it was an electrical problem but nothing those codes indicated. it was the crank sensor that was messing everything up. he told me he would check the codes anytime for me for free. gb .

for the cycle start switch on and off said that is no longer worth a crap and not usable since the 90s. not true... on 00 and up the key cycle is perfectly reliable. the one exception is the 2nd gen diesels 00-02 because of the separate pcm/ecm and lack of any integration. thats why you only got the 1693 companion code that pointed to one or more error codes in the ecm. on the 3rd gen diesels i get all ecm codes displayed on the odometer... both p0xxx/p1xxx generic obd-ii as well as the manufacturer-specific p2xxx codes. it was the crank sensor that was messing everything up. yep - thats something only your ecm would be aware of. he told me he would check the codes anytime for me for free. good deal... most dealerships will charge you a diagnostic fee $60-$90 depending for that. .
