the getrag 238 could easily handle the hemi. it's in the new 4.7L's that have 310 hp and 330 lb ft which isn't far at all off of the hemi. and no manufacturer builds something that close to it's maximum power ratings. not to mention getrag is in the top ranks of gearboxes along with tremec. it's got a helluva lot more power handling than a 545rfe which as ivaskj says sucks donkey *****. i don't need to add a lot more to that lol.

 

Don't both the Magnum and the charger have a manual option with the hemi? Either of those should have pretty much the same bell housing.

 

I poked around the Getrag website, and I think I found what we call the "238". The web address lists the page as "239", but based on the torque rating, overall ratio, and appearance, I'd bet this is the one. They call it the 6MTI520:

I know 1st is 4.23:1 and 6th is 0.79:1, so that would match the overall spread of 5.34

520 N-m works out to 383 ft-lb. So even a Hemi would have a hard time stressing the transmission. It should last until the end of time behind my little V6

 

sweet thanks for the input guys, probly wont happen but was just a thought. haha

 

yea thats what is in my truck from the looks of it.

 

Yep I think that's the baby. Big baby. Good to know I shouldn't be putting any money into my trans for a long time.

 

pretty sure the Hemi has 390 tq when its stock. add a few bolt on performance stuff and you're lookin at around 430 tq. Add a cam, now we're talkin 450tq. Looks like it'd be pretty easy to fry that tranny up pretty good

 

If you thing a hemi with a 6sp is a drag racer, your 100% wrong.

The 6sp manual, the g56 or the g 238 handel the hemi just fine, How ever, thier geared for torque.

Also, the drive shaft and u jiont and ring and pion + gearing are not the same on a 1500 rear diff as per the 2500.

If your going to swap in a 6sp challenger trans, or the Srt manual transmisson, buy the whole car, or the whole SRT 10 Dodge Ram.

I like the 4.7 6sp in a 3rd gen Ram 1500..

 

just as fyi...the 3.9, 4.7, 5.2, 5.7, 5.9 and 6.1 use the same bell housing bolt pattern

the 6.1 does have the starter on the passenger side...

some of the newer dodge v6's may also share this but i have not seen the specs. also the 4bt that came in the liberty's also used the 545 tranny


and for a 6 speed swap...ofcourse depending on the overall goal...the best would be a viper spec t56 swap. the stockers have held up to a 9.49 1/4 mile viper run on slicks and also hold to some pretty modified RC viper powered rams...that we a;ll know weigh a bit on the heavy side


or if you have the money go for the tr6060 in the 09 vipers

 

A built Hemi would probably kill the clutch quicker, but the transmission guts are good for an extra 10 or 20% I'm sure. You're not going to snap an input shaft or split a gear. The truck trans (g56 adn G238) with a big motor will be hard to hold any usable traction in 1st.

A Tremec would be the choice.

Also, the Liberty used a VM Motori diesel.
