Tranny Problems.
 

Have a 97 Town & Country. It throws these codes. P1784, P1776,P0760, P0420, and P0700. Changed the fluid and filter, reset the puter. On crank up seems to be fine and then when you drive it will kick down into third and light up the PRNDL. I was thinking of trying to clean the shift solenoids or replacing them, but I can't find a diagram of where exactly these things are. Can any one tell me where I could get a diagram or tell me where these are? Trying to stay away from the dealer if at all possible.

Ok update. I know where the solenoid pack is now. Driving it now it starts out in 3rd gear and stays there. It will not shift. The PRNDL is all lighted up. I still have reverse as well. Checked all the electrical connections, changed the fluid and filter. Still doesn't work. The fluid was not burnt or even looked or smelled like it was getting hot. There was barely any material in the bottom of the pan. Considering replacing the solenoid pack after what all I have read. What do you guys think? Would I be better off to let a dealer diagnos? Any help be appreciated. Need to get it fixed before vacation time rolls around.

what is the tranny code i know u have P codes the 700 is for the tranny to tell the engein computer that the tranny has an issue u need a better scanner inorder to get into the tranny

RE: Tranny Problems.
 

We got those codes from the local Autozone. Would we have to get the codes directly from the tranny controller or just have a different machine to pull more in depth codes. I know a local garage that has one of them fancy Snap-On multi computers. I know he used it to set the timing on my Tahoe.

u need the dealer computer or yes the snapon computer

Ok ended up taking to the dealer. They said that the shift pack was bad and of course that the transmission was burnt up. Told them they was full of crap cause it don't slip the fluid was in good shape and there wasn't hardly any material in the bottom of the pan. So I guess we will try and get a shift pack and put it on and see how that does.

man I am sorry some people try that stupid crap and pull one over on U dont take it personal there are hacks out there in every dealer i deal with mine all day long. Replace the sol pack and go from there. Get them to give the tranny code b4 u replace anything i want to see what it is.

RE: Tranny Problems.
 

We suppose to have the new pack in today. A question that I have is. The computer is dubbed a learning computer, will I need to reset it or just put the pack on and drive it. If I have to reset it how would I go about this? We took the old shift pack apart and measured the resistance on the coils with an ohm meter. 2 of the 4 where way out. I will see if my father-in-law got the codes from them.

RE: Tranny Problems.
 

the correct way to do it is to do a quick learn after u replace the aol pack yes that basicly relearns all the sections of shifting but sence udont have a scanner that can do tat u can drive it around and it will take some time but it will learn.

RE: Tranny Problems.
 

Ok we changed it and it seems to be working fine. Seems to be getting better the more we drive it. Something that came up and don't know if it is related or not, but the lights on the a/c and heater controls are now flashing. Everything still works fine, but those blinking lights are annoying. Have you ever encountered this before?

RE: Tranny Problems.
 

yeah need to recal the system because u unpluged your battery. here it is
COOLDOWN TEST ENTRY TO INITIATE TESTS: [ul][*]Set Blower motor ON HIGH[*]Set Mode position to Panel[*]Open all A/C outlets[*]Set Temperature to Cold (Both slide pots if equipped)[*]Depress WASH and A/C simultaneously for 5 Seconds [/ul] NOTE: Prior to start of test, If the evaporator is already cold, the system will fail test. To correct, operate system with A/C OFF and the blower motor ON high for three minutes prior to starting test. RESULTS: [ul][*]All LED's will turn on for 5 Seconds[*]Cooldown Test is running when A/C and RECIRC. are alternately flashing. If A/C and RECIRC. are flashing simultaneously, Cooldown has failed. [/ul]

Hello Jon Boy & Chrysler Tech,
I'm not a rookie under the hood, have done all the repairs a shade tree guy can do anymore since the 80's. have changed tranny fluid and filters on my Ford trucks for years, but I haven't done much tothis T&C. dealer replaced the power steering pump on a recall a year or so ago is only other problem we've had.

I think I'm having similar issues to Jon Boy, but I don't have codes. Wifey sez her 2003 3.8 T&C has started "acting funny" when she "tries to go." (yeah, she's blond!) I haven't seen it first hand, but apparently it's not responding to shifting into reverse or drive intermittently. she said"if you give it gas after shifting, nothing happens". I said "do you hear the motor run louder" she sez "nope". I've seen some spots in the driveway, a few inches behind the left front tire and thought it was power steering fluid, but didn't verify it.sinceI travel forwork, she made arrangements for dealer where we bought it to take a look at it today. dealer callsand wants $900 to replace "the front transmission pump" which he later identified as a solenoid or $1600 to replace the "front solenoid" and perform an overhaul, naturally he recommended the $1600 route "since the mechanic is gonna be in there anyway..." then went on to suggest that "if we had any thoughts about trading, now would be a good time..." So, I'm really suspect of their answer. I want to get it back and change the fluid and filter myself and see what's in there, and get the codes if any, like a dummy i forgot to ask.

Jon Boy, is this symptom what you experienced to get your codes? is there another thread on the forum i can search for?

Volman,
This transmission went into limp mode. It had reverse and started out in like 2nd or 3rd gear. It would not shift. It didn't slip or anything else. We picked up a shift pack from the local parts store for around $129. Installed it and that seems to have fixed the problem. Took a little time for the computer to learn the new settings, but all good now.

Chrysler Tech,
Thanks for the replies. It's a shame we don't have people like you working in our local shops.

Jon Boy,
Thanks for that info. Maybe mine isn't quite that bad--yet! I got a code from the dealer: P0944. They said it was a front pump bleed down diagnosis. I'm gonna change the fluid and filter and see what that gets me. Dealer will get me a print out of all that's been done toit, they should have done this at 30K and 60K, but I bet they didn't...

Chrysler Tech,
any info on that code would be great!

thanks

RE: Tranny Problems.
 

the 944 is loss of prime or low fluid . Find the leaks on your van and fill it back up after u do a tranny service. Use RTV not a Gasket when u put the pan back up. As for jon boy move to my area hehe. The sol pack in the humm silver box infront of the tranny not inside the tranny. Has a connector with an 8mm bolt int he middle of it easy to replace not a 900 repair the part is 210 at the dealer stuid hacks .

Hi
I am new to the forum and new to the chrysler as well. I bought this 3.8 L T&C6 months ago .It has 93K miles on it. 2 days ago I was overtakisng a car and the car just she toppped delivering the power to wheels . I pulled to side and same story . Engine revvs but Van does not more . I tried R as well. Trans fluid was clear and at correct level . I took it to an Indi and he has referred to me a transmission guy. What can be the issue. Will the transmission need a rebuild or is it some solonoid which can be replaced without
opening the tranny.
Regards
