This is on a 1991 Buick Regal with a 3800 V6 and 113,000 miles.
If my diagnostic is correct I believe I am leaking transmission fluid from the radiator hoses. There are two small hoses connected to the bottom of the radiator on the drivers side that are visibly wet. The hoses do not look dry rotted and the radiator itself is clean, looking like it was replaced within the last two years. Nothing actively leaks when the car is parked or when idling, but after a drive there are one or two small drips underneath the radiator and the underside of the radiator and front end frame are visibly wet. As such, I cannot tell exactly where the leak is coming from, but I’m guessing it is at the hose connection.
I could probably work on this myself, but I’m short on time at the moment and it sounds like a mess of a job. What would I expect to pay to have this fixed, assuming the hoses just need to be cleaned and reseated/clamped or maybe just replace the hoses and top off the transmission fluid?
On a side note: I was wanting to have the transmission pan removed in order to replace the filter, gasket, clean the pan/magnet, and have some fresh transmission fluid replaced into the system. The local service shop refused to perform this service saying that “I would just be opening up a can of worms” and to leave it be so long as I was not having transmission problems. I’m assuming they didn’t want to be blamed for transmission failure on such an old car over an $80 to $100 maintenance job.
As of right now the transmission fluid is on the very-very light brown side of pink and aside from an occasional hard idle at start and a single noticed slip at high speed (70mph) acceleration, the transmission runs well. Is he right that this service could be “a can of worms” or am I wise to think that this is good preventative maintenance?
