Hi, we recently put a second hand gearbox in our car as ours went. Got it working after a few teething problems and it drove great. Today however something isn't right, trying to pull away at roundabouts ect there just didn't seem to be much power and it didn't feel like 1st gear, also driving along at 60 and as soon as we took our foot off the accelerator the revs would drop down to idle, the same as it was in very high revs at a steady 60mph, the smell inside the car was horrendous burnt oil. Hubby has dropped all the gearbox oil and even though it is still a nice cherry red it stunk. We also lost reverse until the oil change now thats back but it takes a while to engage and is very clunky and jumps back in spurts. Sorry for the long post but this car has my head battered and we can't keep throwing money at it.
