My 5 year old sears 25 HP B&S, 42" riding mower's xmission seems to be giving up. Mower 917.272263 with a Model 323-0510 Hydo Ggear Transaxle. It seems to start out OK for a few feet then the max speed goes to real slow. Barely made it up the ramp into my shop. Had to stop and press on the forward pedal at least 3 times to get up the 6 foot ramp.!No leakage and I keep the trash buildup blow out. Checked the linkages as best I could laying on the ground under it and they appear OK. Can see the brake working although not sure if it is working right. The brake pedal does lock it up in park and seems to release OK because I can push it with the xmission disgage lever pulled out to detent.

The manual lists a lot of parts for it but not the entire assembly so was unable to price it on Sears.com. Rather fix it but know nothing about it. Have sucessfully rebuilt my old MTD manual xmission a few years ago. Been a good mower except Sears replaced the motor after only 80 tach hours on warranty. Started knocking.

Could someone give me some advice and pointers on taking the xmission out and doing a repair or at least refill the fluid. Is there a plug for doing the refill and drain?

Thanks in advance, jayboy70
