RE: TSB 21-08-99
I found this on the Dodge TSB page.
Here is a brief overview:
Here is a brief overview:
Date: April 30, 1999 Models: 1996 - 1999 (BR/BE) Ram Truck 1996 - 1999 (AB) Ram Van
1996 - 1999 (AN) Dakota
1996 - 1999 (BR/BE) Ram Truck

1999 (WJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH A RE OR RH AUTOMATIC TRANSMISSION. Overview: This bulletin involves replacing the transmission regulator valve. Symptoms: Some vehicles may exhibit an intermittent noise from the transmission when reverse gear is selected. This noise has been described as a "buzz", whining", or "moaning" like noise. The noise is most noticeable when transmission fluid temperature is below 38° C. (100° F.). The condition is caused by a resonance of the transmission regulator valve system. Other items may cause regulator valve resonance, including air ingestion into the valve body or out of specification parts. These two items may be the result a possible cracked pump housing, a torn pump gasket, an under filled transmission, a restricted fluid filter or cooler flow, or an out of specification valve and/or valve body. You should remember these additional items / components when you perform your diagnosis. Vehicles built prior to August 1, 1995 may experience this condition if either a transmission valve body or an entire automatic transmission was replaced with components manufactured after August 1, 1995.

Yes, that is the TSB. I had three quotes from 3 dealers in town, One wanted 518.00 ! another 350.00 and the last 180.00. Acording to the TSB it is @ a hour to do. I was there from 11:30 - 4:00. Who knows what they were really doing. Seems to have fixed the noise though.

This repair does work. It's a pretty easy install. The trans valve body has to be removed but not completely disassembled. I did it to my own truck years ago. they changed the design of the valve from a light weight alloy to a heavier cast iron valve. The price of the valve was ridiculously high years ago ($350) considering it just a round piece of machined metal.
