I was looking at another topic and figured out it was the tps so I replaced it and so far so good. I wish the shop I took it to adjusted the bands too. All they did was flush the fluid then topped it off with fresh. They probably didn't even check the filter. Thanks

 

i would like to point out that transmission fluid needs to be checked with the engine at operating temperature(drive 15+ miles), with the engine running and the transmission in nuetral (ebrake on).

also yes transmission flushes are very bad, the correct way to do it is to simply drop the pan and change the filters, and top off the fluid, also make sure that the tranny shop used the correct ATF+4 fluid in that transmission or else you WILL have trans problems before too much longer

also to whoever had transmission problems shortly after a transmission fluid change, if they changed the fluid (did NOT FLUSH it) then they used the wrong fluid in the transmission.

 

I would bet money the shop did NOT use the right fluid. You had it flushed which was the worst thing you could do, now a month later it's gone bad on you. Well you can thank the mechanic for blowing your transmission, and you even paid for it.

 

Yeah if you wanted to pay to have your vehicle wrecked at least enter a demolition derby and enjoy it.

 

Well not to be rude,

but mechanics sell you things like this to line their pockets and to try to make the work easier. It does flush the transmission lines out. However the problem is it also pressurizes the filter from the outside and is therefore not just a light suction. When this happens it literally blows all the fine garbage the filter has caught right into your transmission! Remember the filter is there to stop that very thing from happening!

The second thing that happens is the fluid they use is a very cheap mufti-purpose ATF transmission fluid that is only rated for top off, not for full use! The transmission only takes ATF+4 fluid (or ATF+3 fluid in older years), yet they introduce a cheap fluid and contaminate the trans. Then they still don't use the right fluid on refill, but it wouldn't matter because now that wrong fluid is throughout the transmission and cooling system.

Third, the newly pressurized system blows seals that are not supposed to be pressurized. Again this is why you should purge over flush. Now they will tell you that they turn the pressure down for each vehicle but that's crap, besides as you can see it causes a lot of damage anyway.

The thing is if they are to use a flush they should drop the pan, replace the filter/filters, adjust the bands if they are adjustable, clean off the magnet, and check it for broken parts and ect. Then button it back up and purge new fluid using the pump that is installed already in the transmission. This is called "purging" the fluid.


Now you are a informed customer!

 

Ok so I replaced the tps and it solved one of my problems: surging 200-300 rpms while in cruise but I got a check engine light I went to the closest auto parts store and they put it on their diagnostic tool and got a tps circuit code. They didn't give me the specific code but the guy working there tried a trick with cycling the key in the ignition 7 or 8 times then started it and the check engine light went away. I just drove 400 miles back to our house and the light just came back on while I was in cruise and the rpms surged at the same time. I wasn't going up a hill or anything either. So I really have no idea what it is now and would really appreciate any more help I can get. While driving 70 mph the tach reads 2000rpms but it sounds like its running around 4000 . I have absolutely no power to the wheels hardly until I reach about 40 mph then it picks up speed like it used to. It almost feels like it does right before it shifts into o/d.

 

Did they adjust the bands? Also did you reset the pcm after you installed the tps? Also the noise could be an exhaust leak on top of the muffler. I would do a tune up, cap (brass contacts), wires (mopar performance or msd), champion copper plugs. Clean the tb and iac too. Just my

 

No the shop didn't even drop the pan. I'm going to drop the pan and do it right now. Yes I followed the instructions off this forum to reset the pcm after installing the tps. I also took the throttle body off and cleaned it and put a new iacv in too. Then reset the pcm . I just did a tuneup about 3000 miles ago and used champion copper plus plugs and bwd wires. I took it to a mechanic today and he said that the problem is a bad fan clutch. Does that sound like a possibility to anyone. Thanks

 

Well these fans are very noisy, especially on start-up. Does it sound like a fan? I know my kicks on about 82 if I'm sitting still. Here a link on how to check it yourself http://www.youtube.com/playlist?list...eature=viewall

 

you can check the fan, it is possible that your clutch is siezed up and causing the fan to spin all the time at 'full speed'
