'04 Silverado 5.3 Transmission Slipping

[Xao]

I thought I felt my transmission slip about three weeks ago, but thought I was imagining things....

 

Well today I was driving and pulling off from a red light and DEFINETLY slipped until I tached about 1700RPMs and then grabbed pretty hard.

 

I plan on calling the dealership tomorrow, but was wondering if anyone else has had this problem? I have about 6500 miles on the truck so far.

I have had this happen on my '00 Sierra many times. Based on what I've read on this board, many others have had it happen also. I am surprised to hear that it has happened on a truck with very low mileage, however. I will be very interested to hear what the dealership tells you is causing this.

04' GMC Sierra Z71, 16000 miles-------4 times for me so far.

 

The slip is just one of my problems with this truck. Not satisfied with the performance, brakes and all the clunks, pings, slips, and rattles. GM has let me down with this truck and after reading alot of other peoples post, I'm not the only one.

Add me to the list. There are several problems I have with this truck that are called "normal" by GM and their dealerships but to me are really bad problems:

 

1. Loud clunk when going from Park to Reverse.

2. Transmission shutter from 1 - 2.

3. Transmission clunk from 2 - 3.

4. Slip-Yoke makes noise when taking off from a stop light, going over speed bumps, etc.

5. Cold Start Knock - sounds like a diesel engine sometimes.

 

I am sure there are more, but this is all I can think of.

It happened to me many times with my HD. Luckily it happened to my service Mgr and the Tech when they moved my truck around at the dealership. They updated some of the programming for the tranny and it has not done it for about 1 1/2 years now. A couple of times it would rev up and dump into gear hard enough that it chirped the rear tires.

 

The truck had less than 10K miles on it at the time it was repaired and it now has about 17K miles on it.

Take it to the service department and tell them what's going on. I experienced a similar situation with the wife's AV and mentioned it when it was in the shop last. The folks there told me that they couldn't get any tranny code problems out of the computer, but we'll keep an eye on it if necessary.

I was just about to post something on this. Mine has done it four times in 25k miles. I want to take it to the dealer, but why waste my time? All they are going to do is tell me that "customer complaint could not be duplicated." Does anyone know how to actually get them to look at it? I am assuming if there was any sort of wear assoicated with this random slipping, it could be seen in the tranny fluid?

A week ago while stopped at a light, I had to quickly shift from drive to reverse and gas it a little to get out of the way. (03 Silverado, 4.3 L, 4L60E transmission). It slipped a lot in reverse and surprised me.

 

I was wondering if the computer did this on purpose- like I had too much throttle before it had a chance to engage completely, and intentionally slipped to avoid a hard grab?

 

I would think slipping would be more damaging than an off idle engagement. Anyone know? Had this happen?

Thanks to the guys at LS1Tech! I plan on bringing this in to the stealer on Monday!

This bulletin is being revised to add Model information. Please discard Corporate Bulletin Number 02-04-17-001 (Section 04 -- Driveline Axle).

 

 

Important

Implementation of this Service Bulletin by "GM of Canada" dealers requires prior District Service Manager approval.

 

 

Condition

Some customers may comment on a vibration when accelerating from a stop. This is also known as launch shudder. This condition may occur between 0-40 km/h (0-25 mph) and be more noticeable when the vehicle is carrying cargo or used for towing.

 

Correction

A new propeller shaft, P/N 15071486, has been developed to correct this condition. The new propeller shaft incorporates dual double cardan joints on the center and rear joint positions. Refer to Corporate Bulletin Number 02-00-90-002 for lubrication information.

 

The new propeller shaft will require the installation of a new pinion flange kit, P/N 15071485. The pinion flange kit consists of the following components:

 

A pinion flange

Hex bolts (four)

A pinion seal

A rear axle drive pinion nut

Replace the propeller shaft with the new propeller shaft using the following procedure. Use the part numbers listed below.

 

Remove the propeller shaft assembly and the center bearing. Refer to the applicable Propeller Shaft Replacement procedure in the Propeller Shaft sub-section of the Service Information (SI).

 

Important

In step 2, you must measure the pinion and differential preload. This information is needed to set the preload of the new pinion flange to the correct specification and to reduce any rear axle noise concerns.

 

 

Remove the drive pinion yoke and the pinion oil seal. Refer to the Drive Pinion Flange/Yoke and/or Oil Seal Replacement procedure in the Rear Drive Axle sub-section of the Service Information (SI).

 

Important

In step 3, use this procedure as a guideline to install the pinion flange to the drive pinion and to set up the proper pinion bearing preload.

 

 

Install the new pinion oil seal, the new pinion flange and the new drive pinion nut. Refer to the Drive Pinion Flange/Yoke and/or Oil Seal Replacement procedure in the Rear Drive Axle sub-section of the Service Information (SI).

Install the new propeller shaft assembly and the new center bearing. Refer to the applicable Propeller Shaft Replacement procedure in the Propeller Shaft sub-section of the Service Information (SI). Tighten

Tighten the propeller shaft flange bolts to 70 N·m (52 lb ft).

Tighten the center bearing support nuts to 40 N·m (30 lb ft).

After completing the repair, operate the vehicle in order to verify that the condition has been corrected.
