how to work on transaxlt
@ralph12 , Mary, since there is no mention of which model #, etc., there are 2 types of vent valves one type just pushes in and pulls out sealing on a rubber O-ring and the other type has to be threaded in or out to replace. Assume yours has threads and try turning it out like you would a bolt, if it just spins and does not come out then it probably should just pull out with a little back and fourth twisting motion while pulling it up. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
