I've got a TH350 that was rebuilt last year. How do I increase the line pressure of this thing? IU want to increase it's life. I know I need to get a decent trans cooler - I will get one soon. FOr now thought how do I increase the life of the transmission?


Also, what kind of vacuumn should the shift modulater be plumbed to? Full manifold vacuumn? Would giving it more or less vacuumn increase the RPMs of the shift?

Thanks, im pretty unaware of the black magic that happens inside of transmissions.
