Hi, my transmission is leaking where the piston that moves when the car
changes gears, this thing is located on the right side of the
transmission if you stand looking towards the front of the car.
Will putting a seal swelling additive (leak stopper) harm the vehicle in
any way? I absolutely need the car for the next 45 days and cannot bring
it to the garage during that period.
The car is a 1988 190e 2.3 mercedes.
