Default 04 ram 5.7 Transmission p0700 733 734 735

I really appreciate any help on this. Current 182k.
155k mile trans fluid/filters changed, very very dirty.

Last week all of a sudden my RPM's would increase as if gears slipping.
I checked fluid and it was fine.
I happen to check engine oil and it was very low, but dash showed no sign of engine running hot.
engine light came on giving these codes p0700, 0733, 0734, 0735.
I tested input speed sensor and found no ohms, replaced it.
Problem stopped, but engine light did not reset all weekend.

Yesterday I drove and all of a sudden trans shifted fine 1-2, but would not come out of 2nd gear.
Codes tested same again, spd sensor ohms still good.
Trans pressure sensor tested 50/150 ohms, replaced with new one 100/100 ohms between contacts.
This did not change this current problem.
I drove home 15-20 mph in 2nd gear.

I dropped trans pan and definite smokey smell but not terribly burnt up.
Little shavings but probably from driving home in 2nd.
Vent tube on top of trans is very dirty/greasy.

Tempted to put oil/filters in and see if problem was fluid/filter related, from old trans oil being so bad.
Not sure if I can check any other additional sensors in driveway before putting pan and oil back in, hate idea of draining/wasting new oil if it needs trans shop service.

I really appreciate last minute advice before I call tow to get it to trans shop.
Thanks, Bill

what is best recommendation moving forward: rebuild or new.
Any advice having either done?
Is it possible to trade some power for better gas mileage, never had better than 14.5mpg life of vehicle and actually has been the highest in this last year since changing fluids and adding additives to trans/eng oils.

When you had the transmission pan down, did you look at the side plate on the valve body or find any small piece's of screw heads laying in the pan?

I still have pan down.
I did not find any screw heads.
I did find some very small grinds (about the size of a grain of sand) (not normal metallic glitter), not sure if they were silver or black though.
I was told these grids would have been normal since I drove home in 2nd.

Should I drop plate and look for anything else, I have never gone further than dropping pan before?

It's time for a rebuild with those codes. P0700 is enough alone to know it's rebuild time. Sorry.

I tried to download your service manuals from another post.
My computer got bogged down with "anti-virus" programs that loaded even though I denied them. Had to uninstall and never saw manuals I was trying to download.

If you get a good quality reman its going to be a lot cheaper than a new transmission. I had my transmission replaced at Chrysler. Its still a re-manufactured transmission but cost about $4200 for the transmission. I see third party remans for less than $2000. I should have shopped around. The transmission works great and its warranteed parts and labor through Chrysler, but I paid a lot to get it.

I'm getting pre-evaluation quotes ~$3k vs ~$4k depending if shop reman vs shop installing Chrysler 3 yr reman. This shop comes highly recommended (Circle D)

I'm ready to pass this truck to my 16yr old son, so I want to make a quality 5-6 year dependable decision.

I paid $5000 total for reman trans and install at the dealership so if you are getting installed for 3-4 you are still saving money. Since they are getting the reman they will probably cover the labor if replacement is necessary. If you buy a reman directly and then have someone install it and its turns out to have a problem you might get a replacement transmission but labor is most likely not going to be covered. Hopefully all goes well.

As I shop around I find one shop doing rebuilds 2/days for $1,400. How do I know if shop is reputable. Price is very attractive.

I assume your trans service at 155k was the first. At that mileage, I would not have done it. My oil change guy keeps trying to get me to flush mine. I have 160k, and trans works great on original fluid. No burnt smell, still cherry red. No way I'm gonna let him do it. I had a 2000 Ram with 175k on it, and let him do the flush. 2 months later, my trans was doing just what you described. Replaced the solenoids, that bought me another month or two, and at that point, it was rebuild time. I got it done for $1800. No problems after that. I traded it in at 198k.
In summary, if you have high mileage and have never serviced the trans, DON'T DO IT!!! If you get 150k out of your trans, consider yourself lucky, and plan for a rebuild in the near future.

$1400 is definatly on the low end. The shop could just be trying to drum up some work with attractive pricing. Or they could be using inferior parts. How long have they been in business?? Do they have testimonials?? What kind of warranty, and will they be around long enough to honor it?? Google the shop, and see if there are any reviews. Does the shop look professional, or is it a mess?? Transmission rebuilds need to be done in and almost sterile environment. Any foreign object that makes its way into the guts, could mean serious trouble. I would not hesitate to give the shop my business if my gut tells me they are on the level.

Your right and I had descent fluid change at 155k, I was being told 50/50 to not/do it. what solenoids did you replace, I want to remove plate and check them before I put pan back on.

I don't think trans has any major gear issues since first problem completely fixed when new input speed sensor installed. I think it's another sensor issue or electric controller. Smooth shifting before these issues happened so suddenly.

Anything else DIY can check in driveway with trans still on truck, before I put pan back on.

Thanks for advice, I found some reviews and scratched that shop off my list.

I see rebuilt trans for ~$500. Does it require much expertise to drop and install a rebuilt trans. In general, it seems easier than dropping my gas tank to replace gas pump.

I don't know how difficult it would be to swap yourself. I can agree with you on the fuel pump however!!! I went into that project being told it's just a couple of nuts to drop the tank!! That's a load of crap!! That project fought me every step of the way, the worst part being the fuel line that would kink like a soda straw if you tried to bend it in the slightest!!! I am convinced an access panel in the bed would be the best way to go if I ever had to do it again!

I can't remember the names of the two solenoids I replaced. But I know that due to the metallics that were floating around, the one kept failing. I replaced that one 2 or three times. There's a magnetic property about it that would cause it to attract the shavings and short it out. Talk about a PITA to change!! I think it might have been the governor pressure one, but I'm not sure.

A buddy helping me wanted to remove the complete bed before dropping tank, but me and other wanted to just drop tank, pump looks like it's too far forward to be reached even with bed removed. looks like it sits under extended cab.

Anyway, back to trans, I'm guessing you replaced the solenoid pack behind the plate that connects to the bigger multiwire connector? I'm wondering if my issues are coming from the trans control module itself or that same pack.

My codes/issues don't seem to match any in forums directly and seem to point to electrical.
Knowing i didn't have trans slippage or shift issues before.

got these codes when all of a sudden it felt like gears slipping and rpm's increasing w/out power.

p0700 transaxle control system fault, ie. module may have fault or open circuit in transaxle.

0733,4,5 gear ratios in 3rd gear - trans input/output not same.

tested & replaced input spd sensor - everything was great for a few days.

But codes did not ever reset on own, then all of a sudden, trans shifts great 1-2, but won't shift to 3rd.
replaced pressure sensor (seemed to have bad Ohms, but did not fix problem.)

could internal non-electrical problem happen so suddenly, get fixed by iss, and suddenly have another issue. or should i really be focusing on electrical parts only.

I think I would have perform a clutch test on the transmission before thinking about replacing it. You could have a broken hub with shaft or the underdrive clutches are burnt. Or you can perform a tear down and inspect.
