Default MonteC's Transmission Corner (For Info Only)

Heya everyone.

Mr. Robert Griffin, aka MonteC, is widely recognized on here as being one of the most knowledgeable guys (if not THE most knowledgeable guy) when it comes to our transmissions. This sticky thread is for him to answer any specific transmission questions you may have. I still recommend doing a search before you ask your question, to make sure not to hit Robert with the same questions over and over, especially ones that he (or others) have answered before.

Default MonteC's Transmission Corner, April 5 - April 11

Budget: $500
Tranny mechanical knowledge: I can drain/fill and change the filter. Pressure solenoid doesn't scare me. But gears and bands do. Willing to do valve body work. Limited on tranny specific tools.

What upgrades do you recommend to increase longevity of the tranny (my 2001 currently has only 48K miles)?

Thinking:
Check Valve Delete
Dodge to GM Governor solenoid
Deep tranny pan (turbulator design)
Sonnax sure cure **Edited for answer, and for my own reference**

EDIT
DIYs for above:
1. Sonnax sure cure and deep tranny pan (Thanks squirrel)
http://dodgeforum.com/forum/2nd-gen-...with-pics.html
2. Replacing the governor solenoid (not the Dodge to GM, but the same process) too bad the author was banned.
http://dodgeforum.com/forum/2nd-gen-...d-install.html
3. Check valve delete (Thanks again squirrel)

46RH Rebuilt 22K ago.

Did fluid and filter change, and it seems that there is somewhat of a bog. Shifts excellent, o/d engages / disengages perfectly. fluid at correct level. Its a much smoother ride though, and it gets up to speed very quickly but compared to before the flush it seems like theres a bog. Its hard to explain. My exhaust tone is quieter as well. My exhaust ends after the CAT.

When i flushed the transmission, i found 2 very small pieces of a green "twist" made of hard pastic. Is this something i should be concerned about? Theres was not very much metal shavings.

I already have the factory external tranny cooler.
Would I need to upgrade to bigger/better?
I only tow when moving, but that is about every 2-3 years being in the Army. Other than that, i drive it as little as possible.



Just throw some things out there. Even if it goes over 500. I can prioritize.

--Dan
You pretty much have it covered, sounds like youve done your home work. Only thing i would add is a sonnax sure cure, it will come with some internal parts but the majority of the good stuff is for the valvebody.

I would disconnect your trans cooler lines and flush both the factory radiator cooler and the external cooler, and periodically check to make sure you are not getting fluid from the radiator into your trans cooler. (at every trans service, 25k-30k) SMART BLEND makes a great product for cleaning coolers.

Thats pretty much it aside from pulling out the transmission and installing a better torque converter, lol.

When is the bog? off idle, at cruise? There should not be any "twist" inside the trans, must be something the builder left behind.

I was wondering if you could explain how switching from a 2.2 band lever (stock) to a 4.2 band lever would improve my tranny. I asked the same question to Don from PACT and all he said was "it'll be better". I was just curious how? Is it worth my while? By the way, this thread being a sticky is a BRILLIANT idea!
Also, what do you think about CVC remaned torque converters? I'm considering buying one.

#4L. Fits 518, 618, 47RH, 47RE, and 727 transmissions. The stock second gear band apply lever has a 3.8 to 1 ratio. Whereas this lever has a 5 to 1 ratio giving an extra 31% torque holding capacity in second gear. Placing one pound of force on the tip of the apply lever causes 5 pounds of force on the band. These are Mopar OEM levers.
Is this what your asking about? This is from PACT website.

Worth your while? No. Unless your turning some big horsepower.

Im no mechanical engineer, but i understand how levers work. I might not be able to convey that knowledge easily. Read this website and if you need any further explanation, i can try and help. http://www.eng.iastate.edu/twt/Cours...abs/levers.htm

Will it be better, yes, but its a bit over kill for a stock or a little over stock application, it cannot be changed in the vehicle.

CVC = JUNK

I actually put a bit of 93 octane in my truck and its come out of it. It catches at like 900 rpms and it takes off awesome. I checked my hughes plate and manifold, and my manifold is still all silver, not one drop of oil.

good to know about the twist. To be more specific, it looked like two wires twisted together. but it was hard plastic, and had no wire. two pieces that could fit on the tip of my finger, very small. I have pics in my tranny flush tread.

Hate to drag this out, but I've got the same basic questions as CPTAFW163. I just bought an 03 Ram CTD with only 59k on the clock. I'm gonna use it to tow my 5500lbs camper. It has a 48re tranny that I'm going to do the fluid/filter/band adjustment on. I'm having trouble finding much about the 48re. Any common problems to look for/what would you recommend I do to bullit proof it?

I have a 97 dodge ss/t and I noticed the tranny fluid is milky color and on the way to work today the transmission quit. I assume the trany cooler is leaking into the radiator because the antifreeze is reddish color. What I am wondering is if the transmission filter gets plugged would that stop the transmission from engauging?

On a tranny rebuild, is it always necessary to install a new or rebuilt T.C.? Is there any way of finding out if the old one is reusable? My tranny gave out because I got the lines crossed when installing a remote oil filter so my Overdrive unit gave out. The main case was luckily unaffected. I honestly don't think my T.C. was affected. Could any tranny shop test it and confirm this? Roughly how much would that cost? I'm on a tight budget, but at the same time, if I need to buy it for my tranny, then so be it. Thanks again MonteC, I hope I'm not getting TOO annoying.

I put DIYs for all monteC's recommendations in my original question for all to reference.

I warned you guys that this area may be periodically cleaned out into new, searchable threads. What would be the point of merging another thread into this one, only to create a new thread later when I clean this one out?

Stop asking questions there, ask them here instead. I will eventually lock that thread down with a note to come here instead.

The 48re is a very stout transmission as is. If you want to bullet proof it... open up your wallet and dump all the money out, lol. They have billet input shafts, intermediate shafts, light weight and high capacity drums, extreme heavy duty torque converters, super apply servos, ect A 5500lb camper is nothing when you think about what the truck is capable of towing. Just keep regular maintenance and dont abuse it. Oh yeah and aux coolers, keep that thing cool!

The 48re is susceptible to much of the same things its 46 and 47 brethren suffer from. The governor pressure system is the main culprit. If things look good in the pan i would slap on a gm epc conversion block, and a sonnax sure cure, to start.

If the filter gets clogged to the point that no fluid will pass then yes the transmission will not take gear. There is no fluid to apply the selected clutch, if the torque converter even has fluid in it. But alas, changing the filter may only temporarily alleviate the problem. What ever caused the clogging is an issue, and once the filter clogs it will cause irreversible damage.

Anit freeze or water in the transmission means time for a rebuild. The frictions in the transmission are a paper like material, and are bonded to steel plates using a type of glue. If the temp inside the transmissions boils the water you get steam, and the steam will damage those frictions in a hurry, and just sitting in water deteriorates them.

Sorry Jason my original post was made in the other thread before you created this one.
I thought it might be confuseing to continue the questions here.

Here is a big gray area. Will you ever see me reusing a torque converter on a rebuild? NO. Is a torque converter reusable? 90% of the time, YES.

How long did you run the transmission with the lines on backwords. The converter is in the cooler system, so whatever you did to the cooler lines affected the converter. There really is no way to "test" a converter on the bench. You have to send it to a converter rebuilder and have them cut it open and take a look inside.

What it comes down to is a gamble, im not a gambling man, i have to warranty every transmission i rebuild, so i give a new converter with the rebuild (a cooler as well). Look at the money you have into the transmission, if you can afford to lose that money then take the gamble. If not then you know what to do...
