HST Issues on a L series

[Bwelhoward]

I have a 2008 L 3540 HST. When pressing the the pedal when the auto throttle is on, the tractor idles up and only crawls at a very slow speed. When I engage the cruise it takes off and pulls fine. With auot throttle still on, when reverse is pushed it takes off very fast and the tractor does not idle up. Any help would be greatly appreciated, and I can give more details if this is not enough.

How does it behave when auto throttle is off?

Did you check the connection between the pedal and the trans.?

It travels at a crawl when auto throttle is off as well going forward.

I pulled the connection on the speed throttle sensor and cleaned the contacts and the reverse is working as it should after that, but it is still doing the same thing going forward. I ordered a new speed throttle sensor that goes under the pedal and I’m hoping that resolves the issue.

I just checked the one under the pedal. Is there another one under the platform?
