Question about 2001 Dodge Durango
I just had a rebuilt tranmission put in my 2001 durango 2 months ago. But ever since then it has been in the shop every other week because when I had the cruise control on it felt like it was slipping when I was going done the highway at any speed. now for the last 2 times that I brought it back in. I feels like it is slipping between 65 and 70. It will go up to 3 on the rpms and then drop back to 2. Only when it is running for at least 45 minutes or so. My machanic took it for a ride 30 minutes each way and felt it also but not as much as I did. He informed me that it is not the engine or the transmission. That he doesnt know what the problem is and I should just keep driving it.. I also purchased this truck Dec 27th of 08. Can someone point me in the right direction..
I have the similar problem with 1999 durango. It started about 2 years ago with 90K, the transmission seemed to slip at highway speeds intermittently. I only drive it occasionally now due to the fact that it sucks on gas and has another trans problem, shifting when cold ( i know what that problem is - flat seals until warm). The slipping started getting worse, happening almost all the time at highway speeds 55-70, cruise on and off.
I left it a trans shop for three days, (a place I trust), they found no codes but did experience the problem. I was ready to have the trans rebuilt to fix both problems since I am the original owner and the truck is in great shape otherwise. They said there was nothing wrong with the trans, he said it seemed like the TC was going in and out of lockup and suggested some TSBs that recommend reflasing the PCM? module or computer.
I took it to the dealer and had the computer reflashed for $89, worth a shot instead of $1800 to rebuild. Dealer said if that doesn't work it could be TPS sensor (throttle position). I have seen other forums metioning TPS sensors or trans output sensors.
Well, first weekend i drove it about 300 miles with no slipping. The next weekend another 500 mile trip and it started slipping but not as bad and only with the cruise control engaged.So far it drives without slipping as long as not using the cruise.
Might try a TPS sensor or decide to live with it this way instead of throwing money at it, definitely not going to rebuild until I know what is causing this problem too.

Only way rpms will flair is if trans has low pressure at any time (and allowing internal clutches to slip) or, if the lock up converter is not remaining engaged). This is not an engine problem. Someone needs to drive this with a scanner attached and monitor systems.Other than an internal problem, could be a shift control module, speed sensor or even a problem with something as seemingly unrelated as a brake light switch.
To protect your rights under any guarantee, keep good records on what is done to correct your problem. In working on your car, your problem becomes the shops problem 'till it's corrected!!!

Same problem,same speed 2001 DDurango . It is a sensor chip that has gone out. Replaced , I have gone 18000 miles no more ups and downs on speed control or when u have ur foot on the gas. Better mileage- try a HR air filter and combo it with a Tornado air flow spinner- 4.7 liter engine gets 15-16 town 21 hwy.

if the engine is reving from 2000 to 3000 rpm going down the road with out speeding up it is sliping in the trans something was not done right with the rebuild you need to have the tranny gone back through
