    If I remember right there are 4 bolts down through the unit holding the transmission in place. Support the machine in front and remove the 4 rusted bolts. Remove the wheels first so you can slide the trans out sideways. Do they still cover the trans with that stupid plastic bag? Before you install the trans get somebody to spray some bed liner material on it to protect it. We gave that idea to PG 3 or 4 yrs ago, but they said it costs too much money. Selling replacment trans @ 800 a pop was a better deal for them. PS that Magnum trans is built for a lawn mower.

    Try some Herculiner, you can roll it on yourself.

    not to hard of a diagnosis for me, the right side locked up gradually. the seals swell and they say it costs more to try and repalce the parts than replace with new trans, it could of went the same time i had to change the motor it would of been easier im sure.

    If you are able to take the trans apart the seal replacement is cheap. Maybe about 5 for each seal. The problem is the fert is so corrosive the trans is difficult to get apart. It will make the cases look like swiss cheese after a while. Replacing trans parts is way less expensive than trans replacement, but it is a bigger money maker and less hassle for PG to just ship you a new trans. They don't have to stock any trans parts. If I remember right John @ PG told me they sold 800 transmissions one year. We've had them apart, replaced the seals, cases, gears and the shifter detent. Sometimes the bolts twist right off in the case taking them apart. New case then. This is one reason why I don't recommend PG's any more. Poor design and the trans is out of a lawn mower. It cannot hold up to every day use.

    well it took all of 5 mins to drop trans, if i had the new one covered in the spread on bed liner i could of had it together in another 10 mins. i am gonna tear old one apart it doesnt look to rotted. maybe i can save it and get someone a cheap replacement. should be ok for awhile for me i bought this used and i am not sure how well it was cared for before. with a new motor and now a new trans wooohoooo look out yards here we come. if it would ever quit snowing!!!!!!!!!!!!!!!!!
