M818 won't downshift

[bigmike]

I took the truck for her first ride in 6 years. She upshifted just fine but downshifting to 4th would result in grinding. I can downshift to 3rd when she slows down enough. Again, upshifting is fine, oil levels good. Any ideas? BTW, transfer case was in high.

Sounds like your RPM are still too high. I have this problem with all M809s that I drive. The motor dang near has to be to idle before you can downshift or else grinding will occur. It shifts a lot different than a deuce.

sounds normal to me.

Sounds like 6 years of out of practice.

bigmike...my 818 performs the same way. Just let her wind down a little more.
