My 2001 Honda Accord LX automatic transmission with 103,000 miles has been shifting roughly for about a year. The car is in excellent shape otherwise. I’ve changed the oil & filter regularly @ 3,000 miles, just had the rotors turned. Last year, based on what the manuel says to do, I had the transmission fluid drained and replaced. It seemed better for about 6 months. The rough shifting seems to happen most when going from 2nd to 1st and vice versa. Last week when I accelerated to take off @ a traffic light it made a huge clunking sound & it was like I went over a speed bump as I took off. That sent me to a transmission shop!
Through a test drive & putting on the scanner, shop #1 says it has a major transmission malfunction & said it would cost $2500 to $2600 to take apart, rebuild & put back together. Shop #2 does the same testing & says basically the same thing & all they can tell me is that it will cost $750 to take it apart & put it back together, with the unknown being what is wrong & what will be the total cost! Shop #3, same testing, but they went a step further and dropped the transmission pan & found the forward clutches in there. They recommended rebuilding transmission, replacing forward clutches which includes torque converter, pump, gasket seals, etc. with a cost of $2,000 maximum.
Need your input here! My specific questions are: 1) What is the function of the forward clutches? 2) Does the diagnosis & remedy sound correct & is the price reasonable? 3) Do you think repairing is worth the cost? I regularly get letters from local Honda dealers telling me they’ll buy my car & the last 1 quoted a price of $4,815.
