Guys, I bought my 1320 new, and have the manuals. I can tell you there is nothing in the owners manual on the transaxle other than adjustments for the neutral position. The transaxle in this tractor is a Sundstrand, and is a two piece unit, consisting of a hydraulic unit bolted to a gearbox. The weak point in my unit was the splined couplers that transmit the torque between the two components. I replaced the couplers once, but since the male splines were worn, put the new couplers on with red Loctite... I knew the trans was not going to live much longer, as the gearbox is permanently sealed, and the only way to check the level of the lubricant is to remove the input shaft and look. Mine was bone dry, and even though I filled it with lube, the input gears were almost gone at that point. And those gears are obsolete...

Yes, but he was asking about other transaxles that are reliable, not the original one.

Last year, we had the trans apart, and changed some stuff inside, and ever since then it moved slowly in reverse. Forward is normal. What would cause this? Could it be a linkage, or something put together wrong inside? At first we thought it was just air in it, but I used it most of last year mowing, and it should have cleared up by now.

I'm familiar with them. But it has been a while since I played with a 1320. Probably 15 years now. They were still pretty common tractor when I worked at IH.

I'll get back to your statement a little later...... your terms are all jacked. I really have no idea which parts you are talking about. "Splined couplers that transmit torque"....... is kind of vague. Every part inside the transmission transmits torque. There are a different splined couplers... so, kind of vague. A parts callout or part number of what went bad would help. Don't be too sure parts are unobtainable.

The service manual is much clearer than the owners manual. I'm not sure that I truly believe you that the info isn't in any of the books..... heard that before many times. Sometimes it's just hidden and you don't see it right away.

Cubcadet.com has changed their website around quite a bit. I had the manuals bookmarked, and was going to go back and post a link for you..... but my bookmark no longer works. I can't find it now. I do have a PDF copy of the service manual if you (or anyone) needs it.

Sounds like bad linkage adjustment.
Could it be something inside? Depends.... did you just disassemble the transmission, or the hydro, or both? It could be internal......

My dad took it apart, I don't remember what though, I will ask him. If it's internal, could it cause damage using it? Forward is fine, it goes about half as fast as it should in reverse.
How would I check the linkages? Would the service manual have anything about adjusting them?

Here is a link to the service manual, look around page 2-87 for linkage adj.

J-Mech, Let me see if I can make myself more clear. The 1320 transaxle is two separate pieces, a gearbox and a separarate hydro unit. They bolt together. The torque from the engine is input into the gearbox, but is transferred to the hydro unit through a set of three fingered couplers (PN HG44084P). These couplers are splined to the male shafts. There are two shafts that go from the gearbox to the hydro unit, one for motion in, one for motion out. Therefore, it takes four of these splined couplers to make the unit work. They can still be found on EBay. At one time I had the parts list for the gearbox. I searched the web with the part numbers for the two bevel input gears, and came up empty. With regard to what is in the owners manual, I read it cover to cover, and nowhere does it say anything about transaxle maintenance. The gearbox has no filler or dipstick to check the lubricant level. The hydro unit has a plastic cup under the battery, but I found no reference to it in the manual.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
