| The automatic transmission on my 1999 Dakota, 4x4 3.9 liter, 115K miles, has trouble shifting from second into third. This occurs when I accelerate normally from a stop. For example, after stopping at a stop light. The truck will shift from first to second fine but after that the engine will continue to rev up and the only way to get it to shift into third is to take my foot off of the accelerator and wait for the rpm's to come down. When it reaches a certain point it will shift very smoothly into third and drives normally until I have to stop again. Sometimes though it shifts normally and I don't have this problem. This problem has ben going on for about three years. Last year I dropped the transmission pan and replaced the filter and fluid. The fluid looked excellent. No sign of bad odor or any sign of wear. There was almost nothing in the pan as far as sludge. Very clean. Any ideas? | |

Replying to: jim1958 (Jun 10, 2006 9:23 am) I had simular problems with my 2000 Dakota. Try replacing your throttle position sensor. It's a $23.00 part at most local parts stores. I replaced mine and it cured my shifting problems as well as the bucking issues. You can also try moving your throttle pedal from the idle position to full throttle repeatedly before You start Your engine and determine if it's a tps issue. Sometimes just doing that cleans the contacts in the tps momentarilly. If that doesn't do anything for Your problem, I'd suspect something wrong with the transmission.. also, make sure it's not filled with Dexron. I read some place the Dak transmissions are directly related to the same transmissions used in the H bodys and Dexron causes them to do all sorts of wild things. Did You put Chrysler fluid back in when You changed the fluid and filter? It's my experience that Chrysler 7176 atf is the only thing to use even though the owners manuals say You can use Dexron. Hope this helps Ken

Replying to: scoopyex (Jun 10, 2006 11:18 am) Thanks for the information. When I changed the fluid I used Valvoline ATF+3. It says on the container "Recommended for Chrysler vehicles", and "Recommended for transmissions requiring Chrysler MS-7176. You never know though, sometimes in spite of a message like that it still does not work like the original. As you mention I'll start with the tps. Thanks again. |

| I have a 2000 dakota 6 cyl automatic. When I first start the thing and take off with it, it is doggy and wont take the gas. It dies out and bucks and back-fires. Sometimes I can get it to come out of it by mashing the pedal to the floor until the passing gear kicks in and then let off it when it finally goes, but sometimes it wont work. Sometimes it just needs to go through its fit and then it will straighten out. Once I get it going, it will run fine as long as I dont shut it off and let it sit for a while. It also seems knumb on the acceleration when it is "running right", compared to my friends dakota. I have spent over a 1000 bucks at the garage trying to get it fixed. Mechanic says it is not showing any codes and he cant figure it out either. I trust this guy and have had 20 years of satisfied service from him. So far we have changed battery, complete tune up,O2 sensor, pcv valve, among other things. We are both pulling our hair out and I am going BROKE!!! Someone please help!! | |

Bravo, Ken, for the accurate info on the TPS. I had cruise control issues with it (surging) and the dealer was a LOSER trying to figure it out and gave me the truck back with a transmission leak. After slamming my foot on the gas several times, it worked OK which got me thinking it was a bad TPS. I replaced it and all is well; gas mileage a little better too. Bill

Replying to: amend1 (Jun 18, 2006 8:53 am) Just after I posted it started doing the same thing even after it was heated up. Doesn't down shift until just as I'm stopping and then slips a bit when I'm taking off and then not shifting again until I let off. The tran shop did a flush until the fluid was pure red. But I think they had a one type fits all trans. fluid so I'll drain and replace with the ATF +4. And maybe replace the TPS? Larry
