I have a LT1050 that had been very good over the years. Last week the tranny went and I would like to replace it. I have talked with a couple of repair outfits in my area and it seems like all they want to do is rip me off. I have replaced automotive trannies in the past - those were easy because there's plenty of room under a car. Are there any write-ups on how to do this for this mower? Thanks.
