Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

They are asking for 9 hours of labor ($1,125) to drop and replace the transmission.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

'99 C4 - 60K Miles. As some of you might remember, I asked about trans noise I was hearing nearly a month ago. The day before my service appointment it went away as quickly as it arrived, so I put the issue on hold. Yesterday the noise returned in this manner: I was on the toll way and heard a loud "POP" when I shifted out of second. From that point forward it sounded like a baseball card in between spokes of a bike in every gear / clutch in AND clutch out. It varied with speed. When I came to a stop I felt a 'thump' in the drive line and the noise went away. After that my differential noises returned. Today I went to the dealer. Three techs drove it. Two said it was coming from the rear differential - noise was reverberating up the torque tube. One tech said that it was coming from the front differential. Their advice was as follows: 1. Begin with the rear differential. They are asking for 9 hours of labor ($1,125) to drop and replace the transmission. 2. They want to disassemble the trans in the shop. They would like another 5-10 hours of labor for a diagnosis. They said we can estimate the repair costs from there. If the trans appears okay they will move on to the front differential. I didn't think dealers worked on transmissions. Would you follow this course of action or start with a used or rebuilt differential - I have a independent that will install. They quoted $4,450.35 to put in a rebuilt front differential and $7,700 for the rebuilt transmission (plus the labor quoted above). PM me if you don't want your advice posted.......or have a used or rebuilt C4 trans for sale. Thanks, Jeff

Dealers don't rebuild transmissions. I just had mine replaced for 9.7K with a rebuilt one. My tip was 7200 plus tax, rest is install/tax etc.
