4344 HST issue

[Sackett2]

Had the 4344 HST for over 3 years, and last year noticed a shudder in the tractor in 3rd on the highway. Did a transmission fluid change (300 hours) and noticed no change.
Over the last week or two it feels like its not as fast on the road as it use to be; the top end speed has decreased. Am now researching how the HST operates, but does anyone have any input?

my 2844 does it too. Never really thought much about it as i dont use high very much.

not to revive a dead horse; but thought I would close this with a follow up on the high speed issue-- seems as tho the trhottle cable had slipped at the linkage to the fuel control. easy fix, and yet I worried about it for a year....
