**Note: If your machine is under warranty, I'd recommend only using what oil John Deere recommends to avoid any potential warranty hassles** (not that you'd have any issues, but you know...)

This transmission (two of them) is installed in my John Deere Z960M commercial zero turn mower. I believe it's in several other JD zero turn mowers as well (commercial mowers).

The Tuff Torq web page for this particular transmission is here: https://tufftorq.ordertree.com/catalo...

Torque for plastic drain cap for filter: 8 ft lb
Drain Bolt: 17 ft lb
Drain bolt socket size: 14mm
Amount of fluid needed if you drain from the filter AND the drain plug, 6 qts and 8 oz.

Tuff Torq transmission filter kit part number (around $35 per): 187Q0699150

Part number for Tuff Torq brand oil (if you decide to use it): 187Q0899000 (Tuff Tech Oil - 3 Liter Bottle) You'll need two of those 3 Liter bottles.

I used 5W50 full synthetic engine oil for my fluid change, which is what Tuff Torq used to recommend. I also added Hot Shot Secret FR3 Friction Reducer (1.5 Oz per quart of oil - Substitute the 1.5 oz of the FR3 for the oil...so if you use 6 qts of oil, leave out 9 oz of oil and add 9 oz of FR3). Follow the directions: https://www.hotshotsecret.com/fr3/

**NOTE! Use the Tuff Torq serial number to find what you need on Tuff Torq's website!** For example, search for tzt 13g-r to find a list of transmissions in the serial number range for your particular transmission.

AFTER you change the fluid, follow the directions in John Deere's video for how to make sure the oil is thoroughly worked through the transmissions so you can top it off. It's easy to do. :) Be sure you do this so you don't end up running the oil low:    • How To Complete the Transmission Oil Servi...
