Lawn Tractor Transmission Failure

A:

I understand that you are having problems with your transmission. I have taken some time to research your question here on the Manage My Life website and I noticed that someone else had asked a similar question with a posted response from an expert. I attached the link below for you to view. I hope the link that I provided is helpful. Have a nice day.

I believe the above link is for a manual transmission. Mine is automatic. I have a Peerless LTH2000 tranxaxle with hydro module. I did find a separate post http://www.managemylife.com/mmh/questions/241822-describe-oil-part-730228a-hyd-oil-peerless-trans-weight that describes the part number for the hydraulic oil (Part 730228A) and how to measure the fluid level. However, I would like to know how much oil to purchase. Should the existing oil be drained first, or just add additional oil if needed to get to the appropriate level? If completely replacing the oil, how much is needed - 1 quart? 2? Also, can I buy this elsewhere, such as an auto parts store? If so, is there a specification on brand, or weight (ie, 20W50)? Thank you.

A:

The differential part of your transmission takes 80W90 gear oil. The hydro pump part of the transmission takes a proprietary blend of oil available as part number 73228A which is available HERE .

How you describe the problem makes me wonder if the bypass on the transmission isn't stuck in the bypass mode and that's why it's not driving.

Also, if you've had either of the rear wheels off recently it's possible that the wheel key was not put back or it pushed out. This will allow the axle to spin inside the wheel hub and not drive.

If those things look good then you may indeed be looking at a problem with the transmission. If you put oil in the hydro unit, the oil depth should be from 3-5/8 to 4-3/8 from the bottom of the pump.

Thank you for using Manage My Life!

I believe the issue is the hydro module, but I'm no expert. It was driving fine during my last use on one acre, until about halfway through it started to decrease responsiveness to moving the drive lever. I kept going with the reduced speed as long as possible, but could no longer go up slight hills, and then before completing, it barely moved at all, so I stopped and barely got it back to the garage. The reduction in response was gradual, not sudden. It does continue to move in forward and reverse, but very slowly on a flat surface. I think this is suggesting the hydro unit. Would you agree given these symptoms? I had not had the wheels off recently. I had a mechanic replace my drive belt. He contacted Peerless (the transmission manufacturer) and they advised don't replenish/replace hydro fluid, but recommended replacing the hydro unit. I ordered a replacement hydro unit which will arrive next week. I hope this resolves the issue.

A:

Given what's happened, I tend to agree that the hydro pump has failed. Peerless is rather guarded about this pump and do not recommend doing much to it other than to replace it when it fails. In many cases, that's just all that can be done. Because it's going to be replaced, I would add a bit of oil to it just to see if anything changes.

I just received the new hydro module and kit containing spring, washer, and lubriplate grease. The install instructions include a step to install the alignment tool, part 670384 over the axle and control shaft after attaching the hydro module but before torquing the bolts. There is a caution that both the final drive and hydro will incur damage without this tool installed. There was no alignment tool part 670384 in the kit. Am I supposed to now purchase this separately?

I attached the link for the instructions to working with that transmission unit. You will have to have that tool in order to the connect the 2 units together. At one time the tool came with the unit when ordered. It looks like they stopped doing that. Peerless went through some changes when Tecumseh went out of business so that could have something to do with the tool not coming with the pump any longer.

Thank you for your question.

I am sorry you are having a problem with the tractor. I recommend checking the belt routing first. The belt should be in all of the pulleys. If it is in the pulleys work the brake pedal up and down. The belt should tighten when the brake is released. If the brake pedal does not springing back, I suspect the idler spring is broken. If the brake pedal is fine, I recommend replacing the belt. The belt can be ordered from our parts website: Sears Parts Direct . To install the belt you will need to remove the electric clutch. The image below will aid in removing the clutch. Click on the image to enlarge it. Once the belt is on, check the operation of the tractor before installing the mower deck.

Please let me know if you need further assistance.

If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website: Sears Home Services .

Thank you for using Manage my life.

The idler spring is fine - the belt tightened up when I released the brake. I then replaced the drive belt, but no change. What next - add 80W90 fluid to the hydro module?

A:

If the pulley on the top of the transaxle is turning, make sure the transport lever is pushed in. if it is in I recommend checking the oil in the hydro and final drive. The images posted below will aid in checking the oil. I usually removed the drawbar to access the transaxle.

A:

There should be an arm that comes from the gearbox that has a hole. The Z part of the spring should connect to that hole. once it is connected correctly engage the drive lever. The gear case should rotate forward and tighten the belt. To attach images you will need a digital camera. Once you have the images, add them to the link below by clicking on "add an image" I hope this is helpful.
