I have a 94 Trail Boss 250 2wd that will not go into forward. Reverse works great but forward just clicks but won’t engage. I’ve verified the shift lever is pushing far enough so I believe I have either an engagement “dog” or mating forward gear that are likely bad. I also see a fair amount of metal on the dipstick magnet. But if I ride the machine in reverse the gearbox seems quiet with no other issues I dictated by what I hear. That said I’m in process of pulling the gearbox to see what parts I need. The gearbox has 1341124 as the model number as shown in the photo below but I can’t find any gearbox on eBay or the Polaris parts site that matches that number. Is this 94 model a year that used some special gearbox? My tag on the box even looks different than all the tags on gearboxes I see for sale on eBay. I really want to buy new parts for the ones damaged in my gearbox to fix the one I have but just doing research at this point to see what gearbox I have to know which parts I need. Anyone with experience with this I welcome some advice or direction from what you have learned. Just FYI this machine is new to me but cranks, runs and idles perfect. It’s not beat up and will be a gem when I get this tranny fixed. Thanks.

 

I rarely touch Polaris stuff but if you can find the parts drawing for 94 gearboxes, compare it with those for a year earlier and a year later. This will confirm if it is a "one year only" box. Some makers change a nut and come out with a different part number for the whole box. So I would find out what you need, then start checking the drawings to see if those parts are different for different years.
