I first noticed it in high gears, now it does it in all gears. Seems to slip like the teeth on the transaxle gears are stripped, but I opened the case and all the teeth look good, axles are staying in place. The chain seems like it might be a little loose but not enough to cause the trans to slip. Not sure where to go from here. Any good info out there on how to diagnose these? Thanks

I suspect the shift keys are worn.

Second what Rivets suggested.

I'm not familiar with your transaxle, but some that I "have" seen, have their wheel hubs on a splined axle. The hubs are usually a softer material than the axle (cast iron). If your's is like what I mentioned, check the hub for stripped splines.

Thanks for the replies, I will check the keys this weekend. Other than ebay, does anyone know a good place to locate a used axle? I checked on the price of the keys and they will be around $60.

$60 for the keys really sounds expensive to me. Haven't worked on a spicer for ten years, but I would double check that price.

How can you tell if the shift keys are worn? I took them out and they look good to me.

Left hand key is definitely worn. How do the inside of the gears look, they could be worn also.

Do the keys wear or do they lose their spring? I really can't see anything wrong with the gear teeth or other parts in the transaxle. Is there an online repair manual or troubleshooting guide for these transaxles? Thanks for all the advice..Mike

They will do both. I am going by your pictures, which to me shows the left on larger that the right one, in the side view picture. Remember I don't have them in my hand and transmissions can be tricky. Just my best guess.

The shift keys sides at the bump will wear and get a taper to them which will lead to jumping under load. The sides are about straight up and down on new keys.

Going back into this transaxle this weekend. I found new keys, they look pretty much the same as the keys I took out, I can't really see any wear other than a tiny bit at the tip of one of the keys. All the gears look good, the axle spline and lock rings look good... kinda really stumped here. I found a new 4360-149 transaxle on ebay for $139. Is there a transaxle cross reference that would tell me if this would work? Dimensions look the same and my current 4360-79, only difference I can see by looking at the picture is the 4360-149 has a backup safety switch and mine does not. It says its for a John Deere and my mower is a Craftsman. Of course I would love to fix my transaxle if anyone can give me something else to look at, otherwise I might try to adapt the one on ebay... All advice welcome! Thanks, Mike

Did you ever check this out? Jumping out of gear, and "slipping" as you mentioned, are 2 different things. There is nothing in the trans that can slip. If something in the trans were bad, it would be more dramatic than a simple slip.

Chance, My wheels have a key, no splines... I also checked the drive pulley and gears on the transaxle and the pulley on the motor... all seemed ok. Thanks

try "freemanualsonline", you will need to know the brand, model #, and maybe the serial # for it.

I asked this back in the beginning, how do the inside if the gears look? This is where the keys lock in. If they are worn, the keys will not catch and the gears will free wheel. Also, does it jump out of all gears or just certain ones?

I just thought of something
On some of the peerless teansmissions there is an allen screw on the outside. Behind this allen screw is a spring and a small ball. I just did a repair where this spring was broken. The spring pushes the small ball bearing into detents on the shifter shaft. without these detents working it will tend to slip out of gear. Still though, this would only cause it to jump out of gear. "not slip"

I bought a trans axle off ebay, $68 incl shipping. Works fine, although one axle is a little warped (seller didn't mention_imagine that)...anyways it works fine but the tractor will not roll in neutral. If you put the gear shift in neutral while running it doesn't move and gears R thru 5 work fine. Any suggestions oh how to make it roll in neutral? Thx
