Normally the model K46 & T40A transaxles, that are featured in many tractor. And I would like to know if there is a service manual for this unit that I can get to.

T40A & T40J Normally the model K46 & T40A transaxles, that are featured in many tractor and rider models, do not require any servicing for the life of the vehicle. If checking the oil level/condition, it may be necessary to remove the transaxle from the vehicle. This is necessary to access the fill port (black cap) located under the pulley and fan (see diagram below). After removing the unit from the vehicle, place the transaxle on a level surface and remove the fan and pulley. Then remove the black cap shown in the diagram below. Maintain the oil level at 2025 mm (3/4'1') below the lip of (black cap) port (see diagram below). Technical note: Check oil level when oil is at room temperature (20°C or 68° F) and the unit case is level and secure.

Always use the fill port (under the black cap) to drain the oil from your Tuff Torq unit. Do this by removing the cap and inverting transaxle. Tuff Torq recommends using only using approved Tuff Tech drive fluid when servicing any of our transaxles. Only use the fill port (covered by the black cap) to refill unit. You will need approximately 2.2 liters of oil to properly refill the unit if completely empty.

The amount of oil needed may vary for your service, due to the amount of residual oil remaining in case after draining and the condition/age of the unit you are servicing. While reinstalling the fan & pulley be sure to place all components on the drive shaft in the reverse order from which they were removed and verify proper torque for each bolt. Thanks for your message. While I am happy to help any way I can, you have several questions here that would be best answers by one of our service professionals. You can reach them at or toll-free at (866) 572-3441.

The short answer is the 'AC' designation describes a particular control logic and specific design set defined by a particular OEM for their tractor application. If you contact our professional service team, they will be able to look up and help you understand the features and specifications of the K46AC model. Hope that is helpful, have a great day! There are several differences that can be designed into each K46 unit Tuff Torq manufacturers for an OEM. The main issue with using non-original parts in a repair is the danger of the non-original unit not having the same 'control logic' as the original unit. Meaning, Tuff Torq has the ability to set up a transaxle to have forward/reverse initialized by the control arm in either the 'push' or 'pull' directions (depending on the need of a specific OEM). Using a transaxle from another OEM may create a situation where initializing your tractor in the forward direction would cause it to actually go backward, and vice versa.

So, we do not recommend replacing units with transaxles designed for other vehicles. For more information, I recommend you contact our service team at or give them a call toll-free at +1 (866) 572-3441. Hope this was helpful! Have a great day.

Oil Maintenance Procedures for Residential IHT units with External Expansion Tank Designed to be trouble-free Normally the Residential IHT (K46), that is featured in many tractor & rider models, does not require any servicing for the life of the vehicle.

Due to the design of our units, Maintenance Overview First, remove the transaxle from the vehicle following OEM instructions. After placing the transaxle on a bench surface remove the fan & pulley and pry open the black cap and remove magnet (see Fig #1). Invert transaxle to allow oil to drain from case through the port under black cap. Tuff Torq K46 Oil Maintenance – Figure 1 Refill transmission case with oil through same port to near top of case.

Tuff Torq® recommends refilling transmission with Tuff Torq® hydrostatic oil, available from our service and aftermarket department. Reinstall magnet & cap. While reinstalling the fan & pulley on drive shaft be sure to place all components in the same order as they were removed. In heavy usage applications oil changing is recommended after the 1st 50 hours of operation and every 200 hours, thereafter. The filter should never require changing unless the transaxle is removed from the tractor or rider and opened for repairs.

Finally, after purging the transaxle of air, add additional oil through tank opening (under vent valve) to recommended oil level. (see Figure #2 below for recommended oil level).

Hello I have a K46A transaxle and I took it off the unit as it would run for 20 minutes and then stop moving.

I let it rest for 20 minutes after the oil cooled down and then the unit would run for another 20 minutes. I just saw a video that showed how to drain the oil from it and noticed that there was hardly any oil in the unit, and whatever I was adding thru the air vent would come out after it heated up. Could it just be that I need to add oil to the unit and put it back together instead of rebuilding it? The unit does not whine or make noises when it moves but after 20 minutes it stops. Thanks for your advice!

I have a Craftsman Garden Tractor. It works fine for the last 10 seasons.

It started to stop and transaxle winning before it climbed the hill but it cut grasses fine in flat area in 11st season. I removed the transaxle from the tractor today. This is the info from the transaxle: TUFF TORQ 7A632084620 S/N: 66Y – 0002589 HOP PN: 199973 The reservoir has only small oil left in the tank. However, I have not drain the oil from the transaxle yet. There is no leak (as far as I can see from the housing.

I would like to change and refill the transaxle fluid. What type of fluid it uses and how much? The reservoir has marks and show the level of fluid. However, there is no dip stick on the transaxle housing. How do I know that it is the right amount of fluid?

I will greatly appreciate any info that you can provide. Best regards.

Hello Mr DuBan, It sounds like you need an oil change in your transmission to be sure of what you are dealing with. It can make the transmission run again but it is not a guarantee to fix the issue. But it is a great first step in finding the problem. When removing the transmission from the tractor you want to pay particular attention to the linkage, fan, and all the pulleys on the tractor. By checking these external issues you are making sure that they get eliminated from the list of possible issues. If all is well with the externals, change the oil and see if it helps. If it does, Great, then you had an issue with oil viscosity.

If it does not get better or only slightly then you have wear on the internal hydraulic parts that the oil cannot make up for and a repair kit is what you need to replace the worn parts to get your transmission running like new again. You can always contact the service departments friendly service techs at 866.572.3441 or email.

Hello Mr Robbins, Most K46s hold 2.4 Quarts, however, there are a few that only hold 2 Quarts. It depends on whether or not the K46 in question has an external reservoir or an internal one. The internal reservoir units hold more oil.the rule of thumb is that the sealing cap with the magnet underneath of it is the easiest thing to look at for oil level.

Keep the oil level at 1/3 to 1/2 up the magnet and that will be a good level for the transmission. And as always, if you have more questions you can contact the helpful techs in the service department by phone or email at or 866.572.3441.

Hello, Adding drain bolts to K46s that do not have them can be a problem waiting to happen and in reality not save you much time at all. The problem is having to pull off the lower case off to drill and tap for the drain bolt holes and now you have a new way for the transmission to leak oil.

Time is not really saved due to the fact you would have to still have to remove the transmission from the tractor to put the oil in the unit. We try to talk owners out of doing it for those reasons. However, you can always contact the friendly techs in the Tuff Torq Service Department by Phone: 866.572.3441 and Email:salessrvc@tufftoq.com if you have any further questions or for more clarity.

Hi Guys, I have an L110 John Deere and had a leaking seal on the input shaft. I removed the trans-axle and brought it to my local dealer for replacement. After installing it there is no grunt in the machine. It cannot even climb a small hill.

I removed it again and found the oil level a bit low so I topped it up with about a cup of suitable oil. Could this be the problem, ie. If I need to rebuild the pump assembly/motor can you supply a rebuild kit? I am in Australia and find the John Deere people here only want to sell a complete trans-axle. McCallum, You should check all the external things first. Making sure the control lever is being pushed and pulled through the whole arc that it can travel.

Also, you should check the input shaft and the pulley making sure that the pulley is turning the input shaft. After that, you should check all the pulleys from the engine on to make sure you do not have a problem that way. If those things are all good then you might want to open the transmission and check the machined faces of the center case. Paying particular attention to the areas between the ports.

That is where the oil can escape and not hold pressure and that loss of pressure is the reason you could be experiencing low power. As always, you can call the service department to talk to the friendly techs at 866.572.3441 and see if they can help troubleshoot your issue.

I just inherited an 02 John Deere LTR 180 with a tuff torq K46 transaxle. Everything is working fine but there is a little humming noise when I engage the transaxle.

The article above seems to contradict itself in regards to an oil change. First paragraph says 'Normally the Strider™ transaxle (K46), that is featured in many tractor & rider models, does not require any servicing for the life of the vehicle.' Then 'In heavy usage applications oil changing is recommended after the 1st 50 hours of operation and every 200 hours, thereafter.' What is 'heavy usage?' and should I take the transaxle out and change the fluid? Thank you so much!

I am having problems with my John Deere L130 tractor transmission slipping. Belt and pulleys are new.

My tractor is a 2004 and is in very good condition. If I remove the transmission and change the oil can I drain most of the old oil from the top plug. I have observed someone trying to suck out the oil but he only got about a pint out. I may end up rebuilding or replacing the transmission but I would like to try oil first.

If I have to replace the transmission should I upgrade to a k66 or another k46. If I have to replace the transmission I will contact you for what transmission will fit my tractor.
