The gm transmissions have a weak drum that runs overdrive and reverse. It is a common failure in the trans and it will need a rebuild with updated parts

Here is a bulletin from GM that covers vehicles up to 2005;

#00-07-30-022D: No Reverse, Second Gear or Fourth Gear (Replace Reaction Sun Shell with More Robust Heat Treated Parts) - (Jun 10, 2008)

Subject: No Reverse, Second Gear or Fourth Gear (Replace Reaction Sun Shell with More Robust Heat Treated Parts)

Models: 1993-2005 GM Passenger Cars and Light Duty Trucks

2003-2005 HUMMER H2

with 4L60/65-E Automatic Transmission (RPOs M30 or M32)

This bulletin is being revised to add 2005 model year to the parts information. Please discard Corporate Bulletin Number 00-07-30-022C (Section 07 -- Transmission/Transaxle).

Condition
Some customers may comment on a no reverse, no second or no fourth gear condition. First and third gears will operate properly.

Cause
The reaction sun gear (673) may not hold inside the reaction sun shell (670).

Correction
Important:

There are FOUR distinct groups of vehicles and repair procedures involved.
" Vehicles built in the 2001 model year and prior that make use of a reaction shaft to shell thrust washer:

The sun shell can be identified by four square holes used to retain the thrust washer. Use reaction sun shell P/N 24228345, reaction carrier to shell thrust washer (699B) P/N 8642202 and reaction sun gear shell thrust washer (674) P/N 8642331 along with the appropriate seals and washers listed below.

" Vehicles built in the 2001 model year and prior that have had previous service to the reaction sun shell:

It is possible that some 2001 and prior model year vehicles have had previous service to the reaction sun shell. At the time of service, these vehicles may have been updated with a Reaction Sun Shell Kit (Refer to Service Bulletin 02-07-30-003) without four square holes to retain the thrust washer. If it is found in a 2001 model year and prior vehicles that the reaction sun shell DOES NOT have four square holes to retain the thrust washer, these vehicles must be serviced with P/Ns 24229825 (674), 24217328 and 8642331 along with the appropriate seals and washers listed below.

" Vehicles built in the 2001 model year and later that make use of a reaction shaft to shell thrust bearing:

The sun shell can be identified by no holes to retain the thrust washer. Use reaction sun shell, P/N 24229825, reaction carrier shaft to shell thrust bearing (669A), P/N 24217328 and reaction sun gear shell thrust washer (674), P/N 8642331 along with the appropriate seals and washers listed below.

" Vehicles built from November, 2001 through June, 2002:

These vehicles should have the reaction carrier shaft replaced when the sun shell is replaced. Use shell kit P/N 24229853, which contains a sun shell (670), a reaction carrier shaft (666), a reaction carrier shaft to shell thrust bearing (669A) and a reaction sun gear shell thrust washer (674). The appropriate seals and washers listed below should also be used.

When servicing the transmission as a result of this condition, the transmission oil cooler and lines MUST be flushed. Refer to Corporate Bulletin Number 02-07-30-052.

Follow the service procedure below for diagnosis and correction of the no reverse, no second, no forth condition.

Important: If metallic debris is found on the transmission magnet, the transmission must be completely disassembled and cleaned. Metallic debris is defined as broken parts and pieces of internal transmission components. This should not be confused with typical "normal" fine particles found on all transmission magnets. Failure to properly clean the transmission case and internal components may lead to additional repeat repairs.

Remove the transmission oil pan and inspect the magnet in the bottom of the pan for metal debris. Refer to SI Document ID #825141.
Remove the transmission from the vehicle. Refer to the appropriate SI document.
Important:

" Inspect all the transmission components for damage or wear. Replace all damaged or worn components. The parts list below should be sufficient to correct this concern.

" This condition does not normally require replacement of the transmission completely. Components such as clutches, valve body, pump and torque converters will NOT require replacement to correct this condition.

Disassemble the transmission and replace the appropriate parts listed below. Refer to the Unit Repair Manual - Repair Instructions.

(666) reaction carrier shaft
(669) reaction shaft thrust washer / bearing
(670) reaction sun shell
(674) reaction shell thrust washer

Reinstall the transmission in the vehicle. Refer to appropriate service information.
When servicing the transmission as a result of this condition, the transmission oil cooler and lines MUST be flushed. Refer to Corporate Bulletin Number 02-07-30-052.

I've been hearing a loud clank for a about a week. I continued to drive it since it is my only vehicle and I have to work. I was going down the road and all of sudden I had no gears. I couldn't put in drive, park, reverse. Nothing! I parked it in a parking lot, finally got it home 3-4 days later. A friend came over and looked at the transmission pan and emptied the fluid. There were chunks of metals/rocks in the pan. We cleaned that all out and now they are saying that when that happens it's 92% of the time the transfer case and NOT the transmission. Is this true? Could it just be the transfer case and how will I know for sure?

I'm not sure how chunks of metal could get from the transfer case into the trans pan. Tell me, when you place it in gear and slightly rev the engine, does the speedo work?

Yes it does. And I'm sorry but the chunks are actually in the "screen", not the pan. It will start and act like it wants to go, even did go in reverse once but made a horrible sound "errrr" sound when put back in park.

If the speedo works, my guess is that the transmission isn't the problem. For the speedo to work, the transmission output shaft is turning. The problem has to be after that point. The next area of concern is the transfer case.

Then it must be in the transmission. I have seen seals go bad allowing the transfer case fluid to get into the trans, but never damaged parts.

I got a new transfer case put and it went into all gears and drove and everything. But when it goes into drive, and needs to shift it loses all power. It drives normally in 1st & 2nd gear though. Any idea what could be that cause of this?

When you say it looses power, do you meant the engine dies out or does it feel like something is placing an additional drag on the vehicle?

I mean it's still running but when I go to give it gas it just rev's up and don't go. It just coasts along and it won't shift into any gear by it's self, I have to physically drop the shifter to the gears that work to make it at least go.

Something has come apart in the trans. The only way to confirm what has caused the problem is to take it apart and check.

Just to confirm, your vehicle does not move when you put it in gear, or it is making noise when you are driving?

If it is not moving, then we need to start with checking the fluid.

https://www.2carpros.com/articles/how-to-check-and-add-transmission-fluid

Next if the fluid is the proper level, we should do a pressure test. However, if you heard noises like grinding or clunking and now it does not move, we need to drop the pan look for metal.

https://www.2carpros.com/articles/how-to-service-an-automatic-transmission

If there is metal, then we need to rebuild or replace the unit because once we have metal go through the unit then any repair you make will not last and is just a waste of money.

Let me know if you have questions on this. Thanks
