Mercury Repair Questions? Ask a Mechanic for Answers ASAP
What did the fluid look like? Was it cherry red or was it a black color? What gear is slipping out of gear?
Have you replaced the filter in the transmission?
Did you have this problem before the filter was changed?
If this problem only happens after you make a turn, then the filter is leaking where it goes into the valve body, or the fluid level is low. How are you checking the fluid level? Do you have the car running when you check it?
Can you add 3/4 of a quart and test drive it and see if the problem is still there?
How over full is it?
Around 1/4 or 1/2 quart?
OK then please add 3/4 of a quart and test drive it and see if it still slips out of gear please. I want the fluid level high enough so if the filter is leaking at the seal at the valve body it can not suck air.
