So, my kid is about to take off in his '97 Audi A4 1.8L Manual car to drive 1,500 miles back to school tomorrow. So, we just don't have time to do anything major to fix these problems (it's the middle of the day here on Friday before Labor Day weekend). I just discovered that he has a slow leak of coolant and the manual transmission must also be leaking as the fluid was low and I can see gear oil on the bottom of the transmission....no idea how long this has been going on, but I noticed a small 1" wide puddle of gear oil under the car after it sat overnight. So, my question is whether you think it is OK to put in White Shepherd Transmission Seal (and just leave it in there) and do you have any recommendations for a coolant leak additive for this kind of car with the G12 coolant?
Of course, he can always just stop along the way and check and add to the fluids, but I'd rather do something that was a bit more permanent.
