I have a 2003 Dodge Grand Caravan. My TCM has been replaced twice under 85,000, Again my van is getting error codes (P0888, P1698, P0700) pointing at the TCM. My dash gear selection’s are all boxed in green.
Sometimes the Engine light comes on, then goes off after placing the van in Drive and start rolling forward the greens squares go to normal (only D is boxed). The Engine light goes off after a re-start, if the gear selections don’t all go gen boxes.
Sometimes just banging on where the relay box, the van transmission will go back and be ok again. (perhaps just luck)
I have taken my van to two places and nobody can either get the van to go into Safe mode to get the cods, or then figure out what to fix when/if the cods come up. I have not gone back to the dealer as they only want to charge me for another expensive TCM. I have had the relay box pulled, cleaned and tested as we thought there might be corrosion, no luck.
I think the issue could be a relay a my Engine light coming on (Safe mode) come and go. I have looked around but I haven’t seen any issues like mine. I am physically disabled and use a power wheelchair in my lowered floor van. Finding aa solution is a need for me to go to/from work.
Any thought would be great. Thx for reading.
