In these two videos Dave and Lynol rebuild a Tecumseh Peerless 5-speed manual transaxle model 930-054A out of a 1996 AYP built Weed Eater. This transaxle is very widely used on lawn tractors in 3, 4, 5, & 6 speed configurations dating back to the early 1980’s. You’ll find these on brands from Murray to Craftsman to Husqvarna, just to name a few. It is also very similar to some transaxles made by Foote and Spicer (Dana). These videos are a general overview on how to take them apart and a look at what’s inside. Don’t let these things intimidate you; there not that complicated. If you are good at tinkering and are mechanically minded, you can probably fix your transaxle too!
Here’s a link to a exploded diagram and parts list for this particular transaxle so you can see what exactly is inside: https://www.searspartsdirect.com/partsdirect/retrieveModelAction!retrieveModelDetails.action?modelNumber=930-054A&productCategoryId=1510000&brandId=0796&method:retrieveModelDetails=x
