This part is an OEM from Husqvarna and Jonsered for use with Lawnmowers. The transmission rotates the axle to drive the wheels and move the mower forward. The drive cable pushes the transmission forward to engage the drive belt and spin the transmission pulley when you pull the drive lever up on the mower handle. Replace the transmission if it's locked up or won't drive the wheels when engaged. This part is sold individually. The tools that you will need to replace the transmission are a socket wrench, snap ring pliers, and a wrench.

I removed the drive pulley cable and the wheels and wheel gears and then removed the transmission. I replaced the transmission and reassembled the drive belt, wheel gears, wheels, and drive cable. I also, cut and screwed a small piece of plastic to repair the guard where a rock had pierced it and broken through the guard and damaged the transmission bracket that the drive cable attaches to. It was fairly simple and runs great now!!! Thanks for the part.

Look closely at the diagram on this site and watch a you tube video for help. The diagram on the eReplacement Parts website was very helpful since I wasn't able to find a diagram for the Husqvarna 775EX anywhere else. Get ready to remove the entire rear frame of the mower and the shrouding on the underside. Unfortunately, no good shortcuts I could find.
Note: The model name wasn't exact match but the transmission fit perfectly.
