Tier 1 Transmission Stage 2 Build | What You Need To Upgrade in Your Cummins

My 1999 2nd gen Cummins Ram 2500 came equipped from the factory with a 47RE transmission, and if you’re watching this video you likely already know this is the worst part of these trucks. Follow along as I take the truck to ‪@tieronetransmissions‬ in Arizona to rebuild the transmission the RIGHT way. In this video, I cover what you need to upgrade and why, key failure points in the stock transmission, and the main benefits of going to a qualified shop. When you’re doing something this expensive, you want to do it right!

So, how did you decide to spec out your torque converter... where do you plan your Lock-up to occur?

[@UncouthedChurlishness]

That undercarriage is insanely clean!

[@lawsonayala7903]

Dude fr

[@TroubadourJuggernaut]

wow impressive shop, not too many folks can tear into a tranny like that, such specialized work

[@OvensGarage]

Awesome vid Andrew. Would love to do a built trans for my blue truck some day! I think that's one of the only things I wouldn't want to attempt to build myself on my truck. There's so much to learn.

[@cjaoff-road7269]

Love it man great content awesome video. Keep up the great work.

[@SP01Danny]

He'll yeah siiick. Just overhauled my 48RE. I was glad to see the previous owner had already upgraded & built the transmission.

[@miningking70]

Nice video on your 2nd gen stage 1 transmission. My 2004.5 Dodge 48 re OEM transmission gave me problems, dead OTR! I called Sonnex Rep and Gorend. All Sonnex Billet internal shafts. Personally showed up at the shop with the output shaft kit for the transfer case. Gorend custom built 48re valve body. Stage 4 triple disk converter ultra low stall from Rev Max, Magtech deep pan. Still running strong. I drive an old Dodge pick-up truck!👴🏽👍🏽

[@davidanderson8469]

Amazing shop and skill level. Makes me want to get another auto.

[@Shagggdude3]

If anyone in NorCal needs a transmission built, Pro Built Transmission in Sacramento is best in NorCal. He built my 47re, and it's bulletproof. Great shop.

[@aengus.tavalero]

I’m in sac and have been looking for a good place👌

[@Blackneck1994]

Great video man! I have their stage 2 in my 2006 and love it.

[@CurbAppealHSV]

I’m a year late lol but how’s it holding up?

[@marxfish]

Impressive crew.

[@patrickboyd5670]

Nailed it!

[@brettbernhardt7608]

Hey man awesome video did they mention if there was something to do with a truck with bigger tires for the valve body.

[@ukrainecummins9101]

I just ordered a valve body from them for my 47RE after seeing what they did for your truck. This is coming to Ukraine and it will be great I think. Thank you for the video, I was looking for a good valve body for a long time.

[@quentonmillstid850]

Leave Ukraine! For the trucks sake

[@kevinperez659]

I like the way the truck looks with out the antenna nice clean look ! 👌🏼 how’s reception without it ?

[@davidanderson8469]

Non existent.

[@scottbrewington539]

What are your thoughts on the CA Allison swap? I’d enjoy a write up on that. 3rd with a Allison, potentially the perfect truck?

[@srooster4410]

any upgrades to the transfer case?

[@Soto_000]

What are the specs of that trailer it's a nice one?

[@Balakay9435]

Hell Yeah Brother 🇺🇸🦅

[@Wr3ckZ]

Sooo... Are there any shops (in SoCal) you'd recommend for electrical work on 1st gen trucks? I've got one with a few gremlins I'd like fixed, and any suggestions would be greatly appreciated.

[@JustDiesels]

I personally go to Maximum Diesels in Hemet for anything drivetrain or electrical I can’t solve on my own!

[@robschulhoff7735]

Like to know specs on your trailer

[@darrellpalmer7213]

With the stage transmission build, does the transmission make hard shifts through the gears, or is it smooth like stock?

[@JustDiesels]

That depends on the valve body, but typically stage 1-2 are pretty stock feeling. Mine is more tight than stock, but doesn’t slam me into the seat or anything like a 5 would.

[@davidanderson8469]

@@JustDiesels Mine was a DTT installed by Fred Swanson in Waddell. It was a hard shifting monster. Same deal with downshifting. My buddy just had his 48re done with all Goerend parts and it's a dream.

[@TANKERYANKER2052]

What does a transmission like this run for? If anyone can help

[@JustDiesels]

They have all the pricing on their website that I linked in the pinned comment!

[@Precisionmobile]

What size tires is on that truck?

[@JustDiesels]

35/12.5/17s

[@chuy6028]

4:55 dudes definitely a gymbro

[@kylelagrow1973]

This tier 1 guy talks about valve bodies when talking to himself

[@theredpilllion5922]

First 😃 WGAF!

[@treybrown7815]
