I recently bought and put a new engine in my friends 450-3MC loader. The machine has 13,500 hours on and it has been sitting with no engine for 8-10 years. when it was parked back in 2010ish everything ran fine I know because i remember running th e machine. I've had 4 of these 450-3 over the years so I'm pretty familiar with them.
So on Friday i threw the engine in and got it started. runs great and hydraulics are strong. Im having some issues when the tranny though. it always goes right into forward. but when you shift to reverse sometimes the transmission will just do nothing and sometimes even go forward, and sometimes reserve will actually work. the dash indicator works fine and says its goin into gear.
Ive tried it with the converter cut out on and off doesn't seem to make a difference.
When in forward. you can put it into first with the lever and it will go to first and then shift to second as soon as you give it gas. then won't return back to first till you stop and go into neutral. it digs into a pile very strongly in second though.
so far all i have done is topped off the tranny and hydraulic fluids with Komatsu TO10 and a new tranny filter.
Any help is greatly appreciated,
Thank You,
