We broke reverse at the beginning of a 500 mile race. Ran it the entire race and finished, but when the transmission got pulled apart it needed a new case!!! Something fd it up bad in there. If you pull it most transaxle shops can freshen it up and put a new gear in it damn quick. I like using rick St. John in Encinitas.
Do not drive it, it can and most likely will break more stuff.
I use TRANSWORKS in el cajon.
Very happy with the work and his price is in line with what I have paid for transmission work in the past.
Turn around was pretty fast.
He works on a lot of Mendeola's
