Trans shifting

[EVLDSCO]

Not happy with the way my transmission shifts on my 05 QC. If I mash the gas at freeway speeds (60-70)the trans shifts down and than back up than seems to bog. I had the dealer check it out and they said the trans was OK, but also said they could not hear my brakes squealing when I complained that It sounds like a damn train trying to stop. Stock truck with 8K, any advise?

That's why I prefer to drive a manual transmission, it shifts when and how I say. I have never liked automatics, and I never will.

There is a solenoid on there that goes bad (or IS bad from the factory).... Take it to a different dealer.

Have the dealership change the governor pressure solenoid under warranty. First symptom of failure on our trucks is as you described. The second/eventual more common sympton the dealership will be familiar with because of our transmissions being in diesels is searching for gear on the 1-2 shift under very light acceleration. If you say you have that symptom they'll change it under warranty.

replace the solenoid and while they are at it have them adjust the bands and the tv cable!!!!!!!!!!!!!!!!!!!!!!

Then put a stage 2 on that thing or a SCT and laugh at them RC's while they try to break 14's with a 6sp and 1000 HP to the wheels!

I was wondering why my qc at light accelleration in first shift at about 4500. And when I accellerate about 1/4 to 1/2 it shifts really hard into 2nd. But why then does it sorta slide into 3rd and 4th and not a hard shift?
I am going to push some serious hp soon. Any suggestions for the tranny?

adjust your tv cable

Get an SCT Tuner. Improves shift points, raises rev limit. and overrides Torque Management. It's like night and day!:rock:

try this first bud, sounds like yours is out of adjustment

ADJUSTMENT PROCEDURE

1.Turn ignition switch to OFF position.
2.Remove air cleaner if necessary.
3.Disconnect cable end (3)(Throttle Valve Cable at Throttle Linkage) from attachment stud on throttle lever (1). Carefully slide cable off stud. Do not pry or pull cable off.
4.Verify that transmission throttle lever is in fully closed position. Then be sure lever on throttle body is at curb idle position.
5.Pry the T.V. cable lock (A) into the UP position. This will unlock the cable and allow for readjustment.
6.Apply just enough tension on the T.V. cable (B) to remove any slack in the cable. Pulling too tight will cause the T.V. lever on the transmission to move out of its idle position, which will result in an incorrect T.V. cable
7.Adjustment. Slide the sheath of the T.V. cable (D) back and forth until the centerlines of the T.V. cable end (B) and the throttle bell crank lever (C) are aligned within one millimeter (1mm).
8.While holding the T.V. cable in the set position push the T.V. cable lock (A) into the down position. This will lock the present T.V. cable adjustment.
NOTE: Be sure that as the cable is pulled forward and centered on the throttle lever stud, the cable housing moves smoothly with the cable. Due to the angle at which the cable housing enters the spring housing, the cable housing may bind slightly and create an incorrect adjustment.

9.Reconnect the T.V. cable (B) to the throttle bellcrank lever (C).
10.Check cable adjustment. Verify transmission throttle lever and lever on throttle body move simultaneously
