    68RFE UPGRADES???

    What do you guys recommend the first upgrade to my 68RFE be? Just so I don’t have to worry about anything breaking if I’m running the 200hp tune on the MM3? TIA

    I would recommend not running that tune.

    Your asking for trouble if its not a full built trans.

    Stock power if towing.

    I wouldn't run the 200hp tune.

    You could start by upgrading the valve body and converter.

    Remember though, fixing these week points will put more line pressure and torque through to the other week links in the transmission.

    I've been running the 120hp tune on my truck with the stock 68RFE for 70,000 miles with no issues. If you want to be 100% confident in a transmission without breaking anything then your probably going to need a complete built 68RFE. Do you already have head studs?

    Ray @DRD had a video that discussed this topic, a while back. I think you can still find it on the member's area of his website. They've all been stripped from YouTube for... reasons.

    I'd say at the absolute bare minimum you'd want to install an upgraded valve body (and re-tune the truck with a 225psi trans tune), a low stall torque converter, and a billet flex plate while you're in there replacing the converter. That would give you some measure of reliability... but if you're gonna push the truck hard you might as well go with a built transmission. You'd be a couple of thousand dollars into it with the upgrades I just mentioned, and you're still eventually going to find the next weakest link.
