I need to do a trans service in the near future and havent been able to find very much info on the subject. A write up would be great, or maybe a link to other posts where this has been covered before. I used to do them on Allison 3000's and 4000s but thats it. Also where is the best place for the filter and what are the cap for tranny fluid?

Thanks

Id do pan fluid/filter every 30k miles...

I did mine at 34k, when I first bought the truck, replaced the stock pan with a Maghytec, so I can drain the fluid on the next changed, instead of the mess you make with the stock pan(although I probably could have just bought a drain and installed it, oh well, I got 2more qts in it now)

I also used just mopar ATF+4, picked it up at Napa if I recall, 5qts if doing the tranny with no flush,(dont think youll need all of them, but cant remember how much exactly, might be 3-4qts with the stock pan)

And 3qts for the transfer case, if you have one, might as well change it too, its real simple. Open the bottom plug, drain out, replace plug, open fill plug, fill to plug, done.

 

what about the tranny filter and which fluid type does the transfer case take?

I got my filter from genos, its pretty easy to replace, let it drain for a bit, but you will still get fluid all over your hands, no clean way to do it


The transfer case takes the same ATF+4.
I bought 8qts, and finished up with half a qt, maybe a tad more, left.
But I have a deeper pan too, I belive its one or two quarts over stock.

 

thanks for the relpys. is the new gasket going to be needed and whats the best way to fill the transfer case?

brett

 

The stock gasket is reuseable, my deep pan came with a cork gasket, but I just cleaned off and reused the stocker.
No problem. Im sure some other guys might have some tips too...

For the transfer case, I just put a 6-8" section of 3/8" hose on a gear oil bottle cut off, used it for a spout to pour into the case, it lets you get a little bit of an angle so you can pour it in, just using the bottle you dont have the clearance to tip it up all the way, not to mention the end isnt long enough to not have fluid spill out while pouring it in, the hose lets you stick it in the hole to fill it up, no spillage. Youll see more of what im taking about when you get under there to do it.


Oh, and on the tranny, put 2-2.5 qts in it, then start it up, put it in neutral(ebrake on), and get it up to temp to check the fluid level to top it off.

 

Mine takes 5 quarts in the stock pan drain / filter / fill process.

 

I just did the 5g fush on mine change the filter everyother time 30k.

 

I re posted a DIYtrans service above... check it out

Don't forget to take the TOP plug off the transfer case first! It would be a serious bummer to get the bottom one off, drain the fluid, and find out the top one is frozen on.

Forget who originally posted that tip but worth repeating.

Best,

Steve

 

after you do the filter change its always best to flush the whole tranny with a flushing m,achine, whats the point in adding 5L to a tranny that holds 13L empty, no point in adding that little clean oil to the dirty burnt one.

 

Never flush. Mine takes 5 quarts also.

 

You don't need to ever do a tranny flush! If you do a tranny drain every 30k, no problem. Also, both the transfer case and tranny use ATF+4 fluid.
