2002 LT-1650 will not move forward or backward. Does this mean the hydrostatic transmission needs to be replaced?

I haven't found any info yet on this (not familiar with them)

But, have you checked the fluid level? and the drive belt? I don't know if yours has one but a plugged filter would do this to.

also was it acting funny, before it wouldn't move?

Nothing funny before, but this occurred after the carburetor was rebuilt. The transmission is a closed system, so fluid can't be added and I don't think that there is any filter.

Did you check the disconnect lever to be sure it is moving correctly?

The drive belt could be a problem, or a linkage / belt tensioner problem. Axle keys can sheer off as well resulting in no drive at the wheel. Pulley on the input shaft of the hydro can come loose. Theres lots of things to try before writing off the transmission.

The disconnect lever function looks ok. I'll take a closer look at the drive belt system.

I have confirmed that the transmission drive belt is not broken and the transmission pulley is spinning while the engine is running. I'm back to my original thought that the hydrostatic transmission is the problem :confuse:

I also confirmed that the throttle linkage to the transmission is functioning :mad2: .

Yes, the pulley may be spinning, but there are many times that the key or splines are stripped on the shaft, and the pulley is spinning loose on the shaft. Check this out to be sure.

The transmission drive belt has been changed. It didn't fix the problem. All the other mechanicals (pulleys, linkages, etc.) are ok including the trans. engage/disengage function. I've concluded it's the transmission. The manual says it's sealed and requires no maintenance. However, I see a plug with an allen recess on top of the case. I've tried backing it out, but it woun't budge. I'm afraid I'll round out the recess.

If you jack up the rear wheels do you get any movement? Look at the axle and see if it's turning. If the axle key is stripped the axle will turn and the wheel won't. Unfortunately you may have reached the point where you need a new transaxle. Good luck with it.

I was able to remove the fill plug and the oil level is ok. I jacked up the rear wheels and there is no movement when pushing the forward/rear pedal. I think the transmission has failed.
