No drive in high Range

[Iain]

I have a M1-55DT Synchro shuttle tractor ( M5950 variant?). It has no drive in high range, and low range feels that it may be in crawl. Dash light which I believe is Hydraulic oil is lit. Any ideas what could be wrong?

Have you serviced the transmission oil and filters?
If so, how many hrs on the oil?
How many hrs on the machine?

Haven't serviced transmission oil or filters. Would that be a good place to start? Could a blocked filter cause there to be no drive in high range, but crawl range still work? I've checked that the transmission oil level - it's okay and the oil looks clean.
machine has done about 1700 hors.
many thanks

Yeah.....seriously time for a full service.

Welcome to the forum!
You should definitely service the transmission, and anything else that hasn't gotten attention. An ounce of prevention is better than a pound of cure!

Never heard it put like that....I may have to use that line!!!

Yep, it's way past time for a service!!! Get Kubota SUDT2 oil and new filter.

Might not be the problem though, maybe the lever is messed up and it's in
neutral instead of high?

Thank you for your help. Turned out the lack of drive was caused by a clutch problem, unrelated to the warning light. The hydraulic system has now been serviced as well.
