How does my transmission work?
It started slipping and then stopped moving. The acre of lawn has not stopped growing and I need help.
Thank you in advance.
Frank

That is a mighty broad question! Most likely the slipping was caused by the "shift keys" jumping out of their place, due to plain old wear. If they wear off enough, or break their ends off completely....you go nowhere.
This is what they keys look like. They slide along grooves in the transmission shafts.

Where are these keys, how do I get to them and where do I buy new parts?
Can you also steer me to a manual/
Thank you,
Frank

To steer you to a manual, we would need the tractor model/serial, or the tag # on the transmission. Here's a link to a Tecumseh/Peerless manual to get you started maybe.

Welcome to GTTalk Frank. If you could supply more information about the tractor then there's a better chance of getting detailed help.

Welcome to GTt! Quick question for you. How is the drive belt? Is it possible your belt is worn and just slipping? Like stated above a little more info would help.

Good luck

How long was it slipping before it quit? Perhaps if it was only a short period you have sheared one of the axle to wheel keys. Again it would help if you could post the tractor information.

:welcome: to GTTalk, I agree that we need a little more info...
Make
Model
Any specifics about the problem, including weird noises or etc

I agree with all above.
Just a shot in the dark here, but I'm wondering if you have one of the MTD units that have the 6 or 7 position speed lever on the fender. If so, check to make sure the variable pullies are working properly. Also, these trannies can wear at the axel/case contact, as they have no bearings, only bushings. Once it's thru the bushings, the slop can cause the axels to tip and cause catastrophic damage internally when the gears slip past each other.

Thanks to all! I purchased a new Ariens yesterday, lawn keeps moving! Will work on the MTD this winter.
This seems like a nice site.
Thanks
Frank

Get back with us when you do the teardown on the MTD. Sometimes, if a common trans, you can buy a new complete trans for $75 plus shipping. How bout posting a pic of your new ride?
