My well-maintained '94 rear-drive Toro Model 20438 has stopped working in 3rd gear.  Which is the less costly way to go - attempt to repair /replace the transmission gear myself or just replace the transmission altogether?  A new transmission can be purchased online for $220.  I'm planning on doing the work myself.  Anybody have any experience repairing Toro tranny's?

 i just priced a few gears inside and the come to about $100.00.     if you are not real handy or patient  i would buy a new one
