How to modify your dodge 47re/47rh/46re/46rh valve body for 2nd gear lockup! Cheap and a MUST DO mod

[@kermit1642]

I'd like to see a vid on how to shift and lockup do and don't. Thx!

I’ve gotta fix me 6.7 12v truck (blew the charge pipe off lol) and as soon as that’s working good I’ll get a bunch of clips of driving it with the MVB!

👍👍right on feller.. thanks for another video..see you next time...have a good weekend 👊🍻

[@Hazardous-Hotrod-Knowledge]

Thanks, you too!

To increase line pressure I thought it was counter clockwise rotation/threading out of valve body? Not further in? Isn't it? I'm not positive but going in would lessen line pressure I'd think. Appreciate u taking the time for the vid either way

Thanks for showing the mod. You're videos are helpful. Not sure what the purpose of 2nd gear lockup is? Is this mod only for a transgo shift kit? I cannot do it to my stock valve body?

[@Hazardous-Hotrod-Knowledge]

Glad you like the videos! 2nd gear lockup allows for the torque converter to be locked in second, the usefulness of this is if you’re low speed pulling a heavy load you can hit lockup and it will help pull down your rpm and stop excess converter slip. For going fast it allows for locked shifts which is rapid fire, and no converter slippage for the maximum power to get to the wheels The trans also runs cooler locked up as well And yup it can be done to stock valvebody!

Will this make it lockup by its self like overdrive? Or will I have to hit a switch? Hopefully this will allow me to manually move the shifter into 2nd gear and hit a switch for lock up as I am mostly using this for towing and don’t want it always locking up. Thanks Zachary.

Y’know… I’m not actually sure of that. It should be manual engagement only, I don’t think with 2nd the PCM will have a parameter that fits for commanding lockup and the low speed (it looks at TPS and output speed mainly). You will be able to put into manual 2nd and hit lockup on the switch though, it’s awesome for towing!

Great video thanks!

Will this work for the 47RE as well?

[@Hazardous-Hotrod-Knowledge]

Yup!
