Need some help. Have a 2015 L3301 HST. Problem is transmission is losing power forward and reverse. Have changed oil and filters, no difference. What is my next step.

I am going to provide you with 3 pages from the WSM dealing with the HST.

My purpose is not to encourage or support you working on the HST but rather to get you better informed on the inner workings.

There are two critical valves. A charge relief valve and a high pressure relief valve as you will see in the attached pages. They operate in two totally different pressure ranges.

Except for looking for things amiss in the exterior linkage, serious trouble shooting or repair is best left to an experienced technician with the proper pressure gauges.

Have you tried to run a PTO implement, as you power issue could be as simple as a maladjusted clutch or worse yet a burnt clutch disk, but still way better than an HST issue.

Seems like some time back another person had a similar issue and the rims were spinning on the tires (because of low tire pressure).

How are you certain it the trans, and not the engine losing power? It would be more likely an engine fuel issue...
