Hi guys. I have been having a serious problem with a 2005 CMP25 which has to be accelerated in order for transmission to engage. The problem is that the unit jolts the load when accelerated to up to 1000 rpm in order for the truck to start moving. Transmission has been overhauled as well as the trans valve assy. I just changed the valve assy to a brand new unit and problem still persists. Also if I rev the engine too much in idle, it will overheat due to the hot climate in my country.
Any help will be appreciated.

Regards,
