Oh , that was just a joke . It was supposed to look like my dozer burning . Lol . It was a camper I tore down and burned the floor off of it . Bad joke .
thank you sled dog .So that when you apply the brakes, spool is pushed to neutral. Other wise engine will be trying to overpower and drive thru brakes.
In all honesty @mcprp I don't think your drive problems will be able to be repaired without removing the transmission.
Considering the age of the machine & lack of love it has been given over the years, it has likely been operated with this drive fault for quite some time.
If a 450 doesn't respond to hi/low gear selections, it usually means there are deeper issues than just oil control rings.
My guess is that it has been used for many years with oil control ring problems - which will have now caused the hi/low clutch packs to be damaged due to oil pressure being sent to both packs while attempting to operate.
What has possibly happened is this - while driving the machine in LH low range, LH high range has been getting some oil pressure at the same time & dragging the drive - creating heat & burning the clutch packs.
Testing pressure can help diagnose the problem. However, sometimes there can still be good pressure, but the clutch packs can be damaged & not allow drive.
Try this, if the transmission pressure gauge on the dash is still working, at operating temperature, & at an idle, click through each gear range. Each gear selection should read the same pressure & take the same amount of time to engage - lower pressure when changing & slower engage times indicate where the problem lies.
PS - If you are paying someone to repair the transmission $5000 will barely pay the labour cost & you could possibly double that amount in parts.........
