Hi everyone. Through searching this forum, I was able to track down the code associated with a check engine light that just lighted up on my 2001 5.9l 4x4 quad cab ram short bed. The code is P1740, and through the links I followed from this forum, I found the following diagnostic:

“Either the tcc solenoid or overdrive solenoid system doesn’t seem to be making much sense.”

I’ve had my truck to a couple of local tranny places within the past 7 months due to problems I’ve experienced with shifting. The tranny fluid was replaced in September 2006. Basically, when shifting from 1st to 2nd, it feels as if the tranny is almost hesitating before committing to a shift. I believe this occurs only from 1st to 2nd. If I’m driving in very slow moving traffic, the hesitation shows up as the truck shifts from 1st to 2nd and then back again. Neither tranny place could ID the problem. I’ve discussed the band tension and tranny fluid issues with them, but they could not offer a solution. When the one shop changed the fluid, they said it looked good with no metal shavings in it.

Anyway, to make a long story longer, I’ve been living with the issue since no one can figure it out. However, after I contacted the local dodge stealership about the above code, I was advised that the code is indicating a problem w/the tranny. So my questions are:

1. Does that sound accurate?

2. Anything I should worry about when taking my truck to the stealership? I’ve read horror stories on this forum about people having their tranny’s replaced and it turned out to be a problem other than the transmission. Yikes.
Any help is greatly appreciated. Thanks.

 

I can't say for sure because my Haynes manual only shows P0106 - P0840 or so, but googling for it shows a Dakota with the same problem you describe.

I would see if it is possible to locate and perhaps replace the solenoid(s) itself.
If you can locate them, perhaps cleaning the contacts real good might be all it needs.
Just a thought, but you may find this of further interest: [ul][*]TSB #211100 -- SOME CUSTOMERS MAY COMPLAIN OF A MALFUNCTION INDICATOR LAMP ILLUMINATION DUE TO DIAGNOSTIC TROUBLE CODE P1740 - TCC OR OD SOLENOID PERFORMANCE. *TT (NHTSA ID #614660, OCTOBER 02 2000)[/ul](TSB means Technical Service Bulletin).
TSB information displayed are summaries. Unfortunately we do not have access to the full versions. To get full information about a particular TSB, write down the TSB number & contact your local dealer.

ALSO: The TSB numbers are the NHTSA numbers, which are different from the TSB numbers the manufacturers use. The manufacturers don't give out their TSB numbers to us, so if you ask your dealer for more information about a TSB, have them look it up by the issue date or the TSB title.

 

Your problem is not that uncommon in late model 2nd gens ... here is the TSB that deals with it: http://dodgeram.info/tsb/2000/21-11-00.htm

 

Wow, that was fast! That helps a lot. Thanks again.
