If you installed shift kit need to check what pressures are, make sure they match what ever your build was designed for.
I’ve ordered a trans line pressure gauge kit, firepunk called for 180psi in 3rd locked. I was wondering if anyone might know how many turns I should taking compressing the spring on the line pressure valveIf you installed shift kit need to check what pressures are, make sure they match what ever your build was designed for.
I’ve contacted firepunk diesel and all I got from them is 3rd gear locked at WOT I should have 180psi. And and driving it I can’t even go WOT in 3rd without it slipping and I only have like 140psi before it slips. Also when the fluid is cold the trans shifts nice and goes through all gears nicely but when it warms up it’ll slip the 3rd-4th shift and won’t shift into 3rd unless I let off but both of those go away when it’s cold.IMO, that would really depend on which transgo shift kit you have and wear and tear of parts .
should have a ball park number with instructions. Have you tried to contact Transgo?
Should be pressure testing/checking fluid level at operating temp, ATF fluid viscosity is going to change according to temp which effects pressure.
At a minimum should have line pressure @ idle psi number, line pressure WOT psi number and reverse/front clutch psi numbers.
That is controlled by valve body, I would be contacting Transgo or search on thier website for that info.
There are different versions of Transgo kits, they should be able to give you an idea of what thier parts do to alter pressures. ie how many turns to lower or increase, what springs etc.
