My Mazda has been losing the clutch after exiting the highway going about 80 for anywhere from 45 minutes to 2 hours. The clutch just goes straight to the floor and needed pumping to get any sort of pressure back to keep shifting. After some time on a normal road, the clutch recovered.
Is this something that could have been caused by Jiffy Lube changing the manual transmission fluid at the end of July? There was some sort of leak so we are guessing they did not put the cap on properly. I had a guy at Tire Kingdom flush and repressurize the system and he couldn't find any actual leaks and he said the fluid looked funny to him. After this the car still gave out after highway driving, but seemed to recover more quickly as we just stopped long enough to grab some drive through before returning tot he interstate. I took the car to AAMCO as well, and though he didn't even LOOK at the car he said it sounded like the slave cyclinder? was acting up. I highly doubt that is the case as my car only has 56k miles on it, but I don't know how to solve the problem. We have a road trip coming up and are conflicted about taking my car.
I have not had any problems driving around town, only after highway trips so far (3 times). Help! I have never had any car trouble before.
