But will it hold up like the 8-speed with power upgrades like the whipple?

R.L.K. · Dec 17, 2017

I'd say no due to the 6speed has higher gerar ratios in 1rst , 2nd and 3rd gears , to my knowledge 4th , 5th gears are either the same or very similar.

Don't think its the gear ratio difference but the clutches that fail, but I have seen others talk about these 6-speeds built with better quality components & still fail.
Must admit though 1st gear in the 8-speed is awesome, to bad you cannot do a swap.

The ratios of the first few gears & amt of throttle being applied absolutely determine how much force / pressure is being asked of / applied to the clutches [emoji848][emoji848]

True but the 8-speed has more force applied to the clutches than the 6.

LoL ....it does ....I believe the clutch has ben improved...the 8speed has many changes .. I have a good not a great link as to the Major differences ...give me a bit and I'll post it up Sir , one of the diffs are the clutches...'

The rear differential ratio also plays a big part as you know ...the 8speed is offered in The 321 & 392 ....sometimes the 410 or 456 is preferred .....based on what one does work with his or her Truck ...

Yes I would love to have 4:56 but I am in the same boat as you, 3:55 4x4 front differential is my hold up. Thought about swapping to 3:92 but don't think its worth it on the 6-speed with 3:55, just not enough difference to really feel.
Running 35 inch tires also.

R.L.K. · Dec 17, 2017

Hmm , cracker ....it seems you Sir know my Criptonite.... I have the 14 front diff ...this is why I still have 355 Gear ratio front t & back .....damnit

Just a word of caution to anyone running a MagHytec trans pan, make sure to check the torque on the bolts often. I just found 3 of the bolts essentially loose and the rest were not torqued down to 105in\lbs. Going forward I'm going to check them every time I do an oil change.

Found a pic of the back of a 5 qt jug of Mopar ATF+4 and thought it was interesting how it says its "engineered as a fill for life automatic transmission fluid under normal driving conditions". ATF+4 is no joke

RLK: Question for you:
I am trying to plan ahead even though my first transmission service will be next summer when I replace the pan.

With the screw on or screw in transmission filter is the outside casing aluminum or is it actually metal that a magnet would stick to?
If it is regular metal I was planning on getting a couple of very strong magnets and attaching them to the outside to trap any metal shavings that passed through there as well.

Thanks Lonnie

Another question are these bolts something we can apply a bit of Loctite to to keep them from backing off?

U&A · Mar 13, 2018

Mine was steel if it helps. Still have both of the old ones.

U&A: Thank U! I will plan to apply 2 Neodymium magnets to the outside case of this filter.
Same filter for both! :cheers:

Me personally: I really would like to find out who produces this synthetic ATF for Mopar.
I really am contemplating leaving the Mopar ATF +4 in my transmission and just draining the pan before every summer.
But still dropping the pan every 35,000-40K miles and replacing the filters would still be on the schedule.
Just plan on doing my Transmission Service & Rearend Service @ the same time.
After the new rearend cover is installed the service will take only 30 min.

Also possibly adding this with every filter change.

Yes as always: just thinking out loud!

That's a great idea! Think I'll do that when I drop the pan again. Not that I don't trust the magnet on the MH drain plug but I figure more magnets are better...

SyN · Mar 13, 2018

It Dang sure cant hurt!
You would figure the filter would catch (Most) all the shavings but there are a awful lot that settles on the bottom of the pan.

I only wish the after market would put out a updated better quality filter: Synthetic Media for the spin-on.
