I've not come across anyone having transmission issues that I can remember. Hopefully it's a easy fix.. If you have any codes to read that might point us to some ideas, other than that we'll have to wait to see what the dealer says. Keep us updated!
I've not heard of that brand, how does it compare to line-x?
Line - X is my go to brand. I had one on my last truck and loved it.. had a much better texture and feel than Rhino Liner did.
I use that style for my jetski.. :D
But yes, it's super clean and I've never just really thought about doing it on an actual vehicle. How much is left in the oil pan I wonder after using the top side method?
