MTD only goes in Reverse

MTD Lawn Tractor 42" red

Model #133K679G205 MFG code #1F143840053

sticker on back of trans or rear gearcase gives:
Model #618-0073
Serial # 462698

number on the bottom of trans:

When put in forward drive position and in any speed, when the clutch/brake is let out - it just gives a growling sound and does not move forward. Not sure if its gear noise.
When put in reverse in any speed and the clutch is let out - it moves backward like normal with no unusual sounds.

I ended up breaking down and splurging on a JD 318 before I had to make hay. Mowing in reverse with the MTD would have been a challenge, but was not up for it at the time. The MTD motor is great and thought I would take the trans or drive apart and get the old girl going again, but found you guys. Can you save me some hunting time?

Go to the MTD site

Enter your model number and click the search button. When your unit comes up, click on the transmission to get a blow up of your tranny. I think based on your description that items #15 & #17 are what is causing your problem.

It's not an overly complicated repair, but can take a few hours to complete.

Awesome! Looks like the right parts alright. You guys are worth your weight in gold. A couple hour job for you maybe - for me, probably about 8 hours. Thanks for the help. I like that little red tractor. Time to get the pigeon poop off and get her going again!
