Going to send the coupe in for a trans filter and fluid change in a week or so. For what little they charge it is not worth going to NAPA jacking the car up wrenching then packaging everything up and driving to the recycle center to dispose of it all. I was looking to get a pan with a drain plug for it so trans oil could get changed on an yearly schedule. Everyone seems to list the dimensions in quarts of fluid over stock rather than inches deeper than stock. Anyone have one on a 91 L98 coupe? If so stock only or how much deeper I guess in quarts..LOL Oh and aluminum or is steel fine and if you know of a brand and model that fits well does not leak a real big help..
