while driveing to work in my 2001 4x4 quad cab the tranny went out ofOD, then after 20 minutes it went back into OD this happened twice then my check engine light cam on so i took it to a trusted tech, and he shown me the code then printed it out for me to take to the dealer where i bought it from 2 days prior. I took the list to the deal and left the truck there for there "master machanic" to look at it, keep in mind i dropped it off with the check engine light on. the next day i was told ," i didn't know how to drive a 4x4 truck", and since i didn't back the truck up at least 15 feet the hubs didn't unlock and that is the reason the it went out of OD, and there master machanic told me thecheck engine light was not on when he got it.
Haveing said that i am ready to duke it out with the dealer about the transmission, mainly because my wife works in the office at an Aamco transmission so i trust those techs. but the whole back up 15 feet or so to unlock the hubs thing? is that right? andhas any one else ever had this problem code 1740?
Tuesday i am taking the truck to there master machanic with the light on so he can pull the code in front of me.

 

i am going by when you said dealer you meant a dodge dealer. they were blowing so much smoke up your a++ it makes me sick. i have been a dodge tech for almost 12 years and dodge and ase master tech for 7 years now. there is a tsb for that p1740 tcc code. was not a rare problem either. the tsb number is 21-11-00. it is to replace a small plate on the valve body. and when the pan comes down a good trans tech is looking for a coffe grounds type materialwhich is the tourqe converter clutch, then the trans will need to come out.and as far as the back the truck up thing. what hubs? it is a live axle. dodges key selling point in the end of 93 was the shift on the fly transfer case. this dont have locking hubs. as a mater of fact, i bealive it was either 00 or 01 that chrysler stoped using the vacuum actuator on the front diff anyway. this is the type of experiance that makes people not want to return to a dealer, yes the dealer charges more but there is USUALLY more repairing than guess. this is your selling dealer, they should be trying to make you happy and return for service with them. go back again, if you get the same results, see the general manager, print this and make him read it. they should be tring to keep you as a cust. good luck.

 

yeah mine did the same thing and they had to replace a couple things in the trans. Make sure you get the repair quote in writing Not saying they are all like that but the one I took my truck to quoted me one price then charged me a **** load more

 

Problems with the TCC solenoid have been around for quite a long time.

The TSB refered to above can be read at:

http://dodgeram.info/tsb/2000/21-11-00.htm

note the bit that says:

"Clean the pressure boost valve cover plate to remove any dirt or rust inhibitor prior to installation. The revised cover plate will have a 1.75 mm (0.069 inch) orifice hole versus a 1.22mm (0.048 inch) orifice hole in the original plate. Make sure it is clean."

With such a small hole you can easily imagine how a bit of thrown off clutch or band material could also partially plug it.

 

i am sorry i should have specified about the dealer, i is a road side dealer not a dodge dealer, sorry bout that and thank you for you response. I need to add the master tech also power flushed the trans and my wife was pissed when she found out about that. she says that can remove any evidence there is a problem with the torque converter or other internal problems, i do not know what "tsb " means, and my 4x4 shift is a stick shift not a push button. Would i still have to back it up for that?

 

no as far asI know they are all "shift" type and they are still shift on the fly. You can engage and disengage anytime as long as you doing under 50 mph I think it is. If thats a wrong speed someone please correcct me cuase I haven't had to use mine in a while

 

Never had to back up to disengage 4x4, but I have had TCC code thrown when I had a plug wire burn through and cause the truck to buck thus throwing a TCC code in conjunction with a misfirecode on #4 cylinder, fixxed the plug wire, never had another problem

 

I'm a little on cunfused here. How are you guys getting the TCC code with a misfire the misfire code for cyl #4 is a totally different code. I know I've had both

 

when i was able to retreve the code there was a list of things that could be wrong and misfire was one of them. i was asked by the tech if the truck was sluggish or runing rough maybe to indicate a misfire, that is all

I have also taken the truck to thedealers repair shop with the check engine light on and they ran the cod e and it came up P1740, i had printed out all these threads and the link from hank and shown there tech and told him he can use it as a tool or throw it away, I am still within the dealer warrenty and i would like it fixed. they will look into it.

Thank you very much tojohnalm, HankL, and bluebeast2. without you men i would not have a leg to stand on at the repair shop or the dealer. thank you very much

 

as far as the shif on the fly i have done this 2 hi too4 hi at 75 mph never had a problem.
