Maybe it's been discussed to death but I am worn out on the whole 545rfe. My 5.7 hemi is stroked to a 396 but pump gas only, Is there a way to build one that actually holds up. Forth time around. I keep loosing overdrive. I have had this thing tor. Apart 4 times. Transmission shop is at its max. Warranty now. What can be done to ensure reliability.

With a 545RFE? Absolutely nothing lol. Search the forum for 'ZF swap' or '8HP70 swap'.

We have put in the billet overdrive reverse drum. The best internals. Anything you can do to a valve body, HD torque converter, bigger cooler. And if I am crusing on the interstate and want to stomp it I have to turn off the OD so I can without burning up the clutches.
