I have a 521e loader ser # NCF211879 that when shifting from forward to reverse or the opposite starts out in 3rd or 4th speed briefly and then corrects itself into second gear which it is programmed for. We are stumped and looking for suggestions.
No fault codes on cluster? I'd assume an issue of output speed sensor. Check wires, plugs, sensor itself. Tranny is 4WG120 or WG130? Or other type?
Thanks. Will check on tranny model and check wires plugs etc. we have another 521e so we could switch speed sensor and try it. No fault codes on cluster but am not sure how to check for that.
