So driving home from work yesterday I noticed a strange sound coming from the engine bay. As most MR2 owners know, you are always listening for little sounds or funny smells So some further diagnostics while driving home revealed that the sound changed with speed and also load. So while giving the car a little bit of gas (to load the drivetrain) the sound got a bit quieter. Then once I let the car coast there was a lound sort of ticking / grinding sound.
So I pulled over, popped the engine lid and reved it up a bit (to some strange looks from some construction workers). No strange sounds coming from the engine. So I get it limped home and jack up the back end. First thing I do is check the fluid by pulling the overflow bolt. I lil bit of fluid comes out meaning the tranny is full. Simple solution number 1 eliminated.
So I put the car in gear and spin one wheel. The other responds as it should spinning in the other direction and I can hear something is not right in the transaxle.
So thinking it through, it can’t be the clutch, as the clutch was engaged during my test (and therefore wouldn’t be spinning at all). So I am thinking something in the “transaxle” part of the transmission like the diff or something.
So now I have to drain the fluid, take out the axles and tulips, and see if I can find anything wrong. If that doesn’t work then I have to drop the tranny…ugh.
