545 RFE Transmission Tear Down RFE Most Common Problems 

I guess I'm quite randomly asking but do anybody know a good site to watch newly released series online?

If the canister filter was loose would that let the pressure be weak and the transmission and car would not move at all

Awesome thanks 👍

Awesome thanks

No problem

Awesome

Thanks 🙏

Glad you liked it!

Thanks

Awesome 👍

Thanks bro🤙

Thanks

Thanks man 🤙

Thanks man🤙

I have my moments also🤣🤙

Yes stock 5.7 besides camshaft

Can't wait to install it. Need some extra time to get it done.

@@FrostbiteRam ikr!!! I wanna get the body rite on the Durango bro!.....been busy a.f. with work my goal is to b ready for cletus and cars Houston

@@bmanclassics4350 same here man work been crazy.

Glad it helped

Not sure I haven't heard of anyone trying that.

I have tried it in a Dakota. It initially went into gear, within about2-3 minutes it started violently banging - it seemed like it was trying to go into 2 gears at once. I popped into neutral and stopped. Then it would only go into reverse. I thought I had destroyed the trans, but fortunately I went back to atf+4 and it was like nothing ever happened. These trans are VERY picky about type AND quantity of fluid. Little over/under full and they will slip, go into gear slow etc.

You can by the factory clutches from dealership i believe

@FrostbiteRam is there better options besides factory parts like the pump and valve body?

Definitely possibly 🤔

Details like that are exactly why a novice like me fail the first go-around😊 First junkyard tranny swap I did, I didn't know to prime the torque converter with as much fluid as possible. Those kinds of mistakes (that require hours of labor to fix) are the worst.🤦

You have a 65RFE if there’s 6 gears. The first number represents the number of forward gears. Your transmission has a label on the left side of the case just above the pan that identifies it also.

Really don't know what size it is. You could probably ask nitrous express.

From my experience there is no way to make a RFE trans hold power for long term use. But if your not running a power adder and drag racing it constantly it will hold up for a decent time. However the absolute best option is a good used factory trans or a new oem unit the rebuilds don't seem to work well from what I've heard and seen.

I have, the pressure can be increased with tuning. The new kit is just a way to increase without tuning.

@@FrostbiteRam what dp you think about the pressure plate they have? Im getting ready to rebuild my 545 and am considerkng the extra capacity plate

I also have a crd and I'm pretty sure I cooked the TC from low pressure

It depends on year but I believe the 8speeds have the computer as part of the transmission.

I believe that is part of the valve body/solenoid pack asm.

Maybe in wrong o think I was seeing a part below the plate not the actual plate pushed out. My bad.

Very possible

Yeah them crickets was on a roll🤣

Not sure

Best advice do a 727swap or a 46re swap like I did if you want over drive best thing I ever did.

If racing from digs it can hold pretty well. But if roll racing and you let the trans kick down to many times it will not.

Yes

That is the million dollar question I'm not sure. I'm leaning towards not enough pressure and perhaps bad install or fitment.

@@FrostbiteRam I would be worried about rebuilding it and throwing it in your truck without knowing that. Do you plan on replacing the valve body during your rebuild?

@@chrisrussell6538 probably not, I actually have huge plans coming up for transmission upgrade. Lets just say frostbite will be on a next level.👍

On these transactions the computer needed to be set in quick learn mode or it will fail prematurely. As the transactions wears the computer compensates. When trans is replaced the computer doesn't know it's new.

Most likely factory Mopar clutches. It seems to me that these transmissions work best left completely factory. Many had tried to upgrade them with aftermarket parts and most has still failed or failed faster than a stock transmission.

Frostbite Ram that’s probably true, I’m on my second trans but only because one of my lines came off on the freeway. My second one has been holding well though. I have a billet valve body that I’ll be installing next, not sure if it’ll help lol

46re swap from cope racing is very awesome he can do trans Break and manual valve body.

@@FrostbiteRam thanks man, I'll keep that in mind as I have plans for a Hemi💪

Had the same issue with mine and I have 180k tho but I’m pretty positive mine are shift cylinoids

From what I have read, you may be in what they call "limp mode". It's a preset failsafe that limits the transmission once the solenoid fails.

I'm putting a little bit more than that through mine and its still holding. If you stay around 500 Mark it will hold up pretty well if tuned and driven right.

@@FrostbiteRam your 545rfe is holding up on 500hp? I've the 545 fail a lot on anything over stock. Also have you heard of anyone doing an 8speed swap in the 3rd gen rams that is successful

Sonnax line pressure booster, shift kit, better clutch packs.

Very possible ill look into that.👍

That's what I've read is a common failure on these. And even after experiencing some slipping, a new valve body assembly can keep the unit running for many miles. Obviously, those clutches wouldn't have benefitted from such an easy fix.😊

Yes the one still in my truck has 148k on it right now and still going strong 💪

Really don't know just is what it is🥴

@@FrostbiteRam burnt clutches are not the cause, they’re the result of another problem. There likely was not enough pressure exerted by the apply piston. This could be caused by leaking seals, an issue in the valve body, a leaking solenoid, etc.

Not sure really.

Nope just putting it in the trash lol

Awesome

I can't seem to find out how many quarts of transmission fluid goes back in. I've seen 14 I've seen 12. All I know is when I get it back in, I don't want to go back to the store.

@@jasonhess3903 the owners manual should say. I wish I remembered but sure don't off top of my head.

The 5 and 6speed is basically exactly identical.

Pretty much

Not really sure this trans was given to me from a friend who has a boosted ram and similar setup as mine. The transmission was supposed to be fully built but didn't hold long so he did a gm trans swap to his truck.

Man that would drive me nuts not knowing the actual reason it failed but I love your truck watch your videos all the time thanks for all the good information 👍

Possible air leak in pump perhaps. Try message cope racing on his RU-vid channel he may have a better idea.

Change the canister filter. The pump is bleeding fluid back into the pan overnight. It may not be seated properly or the check valve could be faulty. Mine have all done it too some worse than others, but the filter swap usually fixes it.

@@codylapoint Thanks for the info. I changed both filters when I first bought the jeep at 135K miles and the problem did go away for about 2 weeks, but sometimes it will go for a few days without doing it anyway so I wasn't sure if it was related. Seems to do it more if Im parked on a incline overnight. I'm at 175K now so I think I'll change them again. Thanks again

I’m about to install a histall, shift kit, and upgrade the clutchs. I was calling around for pricing and two trans shops told me about the filters. One trans shop said to buy the dodge filters not after market ones. The aftermarket ones can cause the problem you’re talking about.

@@Itslikethat313 Yeah, both filters came from Mopar last time. Im ab to change them again. I mostly eliminated the problem by parking on a level part of ground beside my house at night

Could be bad speed sensor or solenoid

@@FrostbiteRam shift solenoid replaced last year --input output sensors also replaced last week still in fail safe mode

have same code, replaced my solenoids p0734 is gear ratio error in 4th so I will begin my rebuild this month

Nope, but it does last awhile

Could be slipping clutches

It’s throwing another code as well p0700 transmission control system (mil request) it won’t shift past first in drive but you can manually shift it to second

Have no idea but definitely sucks

Sometimes! Rebuilders forget or simply don't know ( yes there are some that don't. I've run into a few of them over the years) that You HAVE to soak all clutch disks in transmission fluid for a few hours at the very least before they get installed. So while I can't tell if that was what caused this particular problem, this is one reason I've seen some burn out pretty fast after someone rebuilt. Another reason can be due to the spacing in the trams is wrong. Another reason is ( if you saw him looking at the over drive stage Part.) the rings on the shaft may have gotten nicked or torn. While most of the time, if this has happened, it will be noticed very quickly as the transmission won't shift correctly . But also, if it's just a slight nick, it may take it a few miles before it shows not shifting properly. Then of course there could be a problem with fluid flow. Pump having something wrong with it and a number of other reasons too long to get into here. But yeah, I too wish he'd have told us what he thought the reason it burned up was.

@@tonym3675 thanks so hard to tell sometimes.

It will be worn clutches most likely

Frostbite Ram Easy to fix your self, all new trans, or a professional job?

@@jamesadkins805 I really don't think its that bad to do. But honestly its hard to beat a good used transmission on ebay or a salvage yard.

Frostbite Ram appreciate it

Correct

Faster/Better than the 8speed?

Nope decided to swap to a fully built 46re

@@FrostbiteRamActually a better route!

@@GearHeadsRestorationsllc I did a 46re cope racing transmission swap fully built with manual valve body and transbrake. I have many videos on the swap

@@FrostbiteRam Thats a sweet build. I actually own a shop and do transmissions builds. I watch others now and leave good comments if the build looks good. Let me know how that one held up for you!

@@GearHeadsRestorationsllc awesome so far its been perfect

Yes he hasnt upgraded it yet

Yes I still on stock converter 🥴

@@FrostbiteRam me too I wanna do a 2800 to 3000 myself....

Yes

@@FrostbiteRam yes what? What year model is the 545RFE you were working on?

not really lol

Oh yeah 👍

Go check out high performance rfe rams on Facebook

734 is gear ratio error in 4th idk bout the others

Lol🤣🤷‍♂️🍻

Because it's junk that's why lol

Nobody has had any luck with rebuilt rfe trans

@@FrostbiteRam I heard it was bad but didn’t know they were that bad

Best option is new unit or a unopened used junkyard trans

🤣🤣🍻

😂😉

@@FrostbiteRam what are you winking at? This video is lacking. You could have done better.
