Allison mt643 trans torque capabilities
Hi I'm new to this forum but am impressed with the knowledge y'all have.
We are buying our first diesel pusher, a 2000 Winnie journey with 275 hp isb cummins and a Allison mt643 trans. I am kicking around the idea of turning up the engine some, not radical but more torque, maybe 100 ftlb or so. I have a 1996 ram with a 12 valve and turned it up over 750 ftlb it has over 250,000 miles and have had not one problem with her, so I am not worried about the motor, but am concerned about the trans handling it. I know cummins is conservative on what their engines will take, and I'm sure Allison is he same. I haven't been able to find anything out on this. So my question is will the mt643 take more power or would it require upgrades( line pressure or other mods to help with holding power).
Any help advice or prior experience would be greatly appreciated!
Thankyou darren
