Have a 96 Accord and the trans is slipping sometimes but seems like only when the car get warmed up or running for a while. Any suggestions. Is there a linkage in the shifter that can be adjusted?

 

First step is to check your trans fluid after driving the car for 15-20 minutes. If it doesn't look like cherry cough syrup, the fluid is the problem. There are plenty of topics in here on how to change the fluid if that's the case.
