how many miles...? sounds like bad driveline joints. most of the similar shudders related to the tranny are under an accelerated/loaded condition, i would start by checking some u-joints, and axle joints.

 

Just turned over 60000 miles. I pull a 5th wheel with a gvr of 13995. I pull in 5th and usually run 195-200 on the hot side of the transmission. Would bad u joints explain why my rpms stay high instead of dropping off and let it coast freely? It feels as if the transmission is slowing me down.

 

yur description is kind of vague... are in tow/haul ? are you using the exhaust brake ? and possibly a stuck caliper or warped rotor ?

 

Bad vibe

Do some trial and error on it, take on an unbusy road get up to speed throw truck into neutral, coasting roll down window and listen and feel for vibration, let go of wheel even see if it pulls one way, if you can determine and eliminate certain components you can zero in on vibration alittle better. good luck

 

No I am not in tow/haul and the exhaust brake is off. Thanks for the advice and I am going to investigate a little more on my way too work.

 

im having the same problem with my 08 with 81,000. when i stop it would act like the converter was still locked and now its even stalling the engine when stopping. would like to know whats the problem and the dealership said there is nothing wrong with the tranny.

Low fluid is a big cause of this.

 

If the torque converter clutch (TCC) is staying locked when it shouldn't be (like at low speeds or at a stop) it should be caused by either an internal converter failure, or by a stuck (or sticky) TCC switch valve in the pump. You'll need to pull the trans, pull the pump assy (the TCC control valves are in the back half of the pump assy), and check to make sure all the valves slide nice and smoothly in their bores. If you find the TCC switch valve stuck or sticky, clean it up and that should fix it. If the valves are all OK, replace the converter.

If you do this yourself, BEWARE because it is VERY easy for one of the thrust bearings inside the input clutch assy to fall out of position when you pull the pump out. The input clutch assy is the next big "chunk" of parts behind the pump. If a thrust bearing falls out, the pump will not seat up flush against the case face (by hand) when you go to reinstall it, and if you just crank the bolts down, you will break the bearing, and have no end play on the input shaft (it will also be difficult or impossible to turn). You will then experience a complete trans failure after about 300-600 miles (with so much fine metal debris that you'll have to replace the entire trans). So it is best to ALSO pull the input clutch assy, diassemble it, and grease all the thrust bearings (with Vaseline) to hold them in place. Extra work, but a lot less work than a trashed trans. Or, HOLD the input shaft while you pull the pump out, and be very careful (making sure the pump seats OK) when you reinstall it. If you have no end play or can't turn the input shaft, open 'er back up and check those thrust bearings.

 

Your were right. 4.5 quarts low. Hope I didn't mess anything up. I should have checked it after they put new filter in 3 months ago
