okay when driving sometimes my RPM's spike about five. had a transmission flush about 10K miles ago. anybody know the cause for this. 2000 dodge durango 4.7 L V8 4WD got 132000 on it.

 

Seeing as you have a 2000 with the 4.7 you most likely have a 45rfe transmission. When you say you had it flushed, they dropped the pan and replaced the fluid and not just use a machine correct? When they do this is leaves debris in the lines and can cause major problems.

It sounds like you're torque concertos lockup gear may be disengaging so I'd click the O/D Off button and then push it again and see if that helps. They did change the filters too when they replaced the fluid too correct? If not, there could be your problem.

 

i agree with widow a transmission FLUSH is a bad thing, a fluid purge is fine (this is done with no extra equipment by u sing the trans pump in the truck)

and the filters are a must

 

As I read it, he says a "Flush" not a drop and fill. Thus... flush failure sounds like the likely culprit here. Oops.

When you replace the trans, get a new TC too.

Never do a transmission flush! All that does is blow all the crap the filter/filters are trying to filter out through the transmission (where it's not supposed to be in the first place!) and blows your transmission cause that crap gets stuck in lots of places.

Second thing they do, is because ATF+4 is so expensive they flush your transmission with a cheap fluid called Multi-Vehicle ATF transmission fluid. Your truck is not supposed to use this fluid and if you even read the sheets it states for use on "top off" not regular use. I wont even let people use that fluid for top off as the owners manual even states to ONLY USE ATF+3 or ATF+4.

(By the way, ATF+3 was replaced so if you use it in the older versions you need to use ATF+4 now, it's a better fluid and ATF+3 is out of manufacturing.)

Anyway, not only do they blow all the crap into your transmission, and use the wrong fluid to do it, they also leave the same WRONG fluid in the transmission when their done! That's right! They fill your transmission with the wrong fluid! The right fluid is 3-4+ times more expensive so they don't use it. A good shop would tell you that flushes are crap and only a pan drop, filter change, adjust if necessary, fluid purge if it is burned, and bolt back up is the correct way to do it right.

Now you drive away thinking everything is fine but in fact now your sittin on a time boom waiting to break on you! You made it 10k, you did pretty good sorry to say.
