Would like to hear from whoever has done a Cummins 4bt swap about what you used for a slave cylinder . I am running 2nd gen style bellhousing , a 2nd gen flywheel , a NV4500 and a 205 T-case . I run the NV4500 specific fluid in the T-case also so I know contamination isnt the issue . I have a 93 Dodge P/U with a NV4500 that seems to shift a lot nicer than the jeep . Is the weight of the flywheel a factor ? The flywheel is as I stated for the 6BT . Any ideas ?
