98 acura cl 3.0

Our tranny is slipping some, had a pressure check done and the mechanic gave me a quote of $3.5K to repair it. I only paid that for the car and it has 150k miles on it now. What is a good solution here…

There were major trans problems on some years so might want to check on whether there is any warrenty. Think it was more like 01 though. Otherwise probably time to trade. Heck of some good deals out there now.
