transmission numbers and identification
 

OK first off this is going to take me a little while to get all this on here. I'm going to put every thing I have about matching up transmission numbers. I got some of this info from a family member who works at the transmission plant in Kokomo Indiana,and the rest from different places. A few things to remember when looking for another trans. In mid 99 they changed some of the electronics.96 and up A500, A518, and A618 use the same governor pressure solenoid. 96-early 99 A500,A518,and A618 use the round metal pressure sensor or transducer as some call it. Late 99s and up use the black plastic 1.
96 -early 99s use the same OD & lockup solenoid. late 99s and up use the same OD & lockup solenoid. 78 -98 uses a round black neutral safety switch with 3 pins.For 99s they changed the neutral switch to a rectangular white plug with 3 pins. In 2000 they changed to a 5 pin big plastic switch
If you look above the pan on the drivers side there will be some numbers stamped on the case most of the time they start with PK. The next 8 numbers are the part# for that transmission. Also if there's fins above the rear servo it's a A618. Diesel and V10s have a moon shaped cut out at the bottom of the bell housing for a bigger torque converter.

I will add more when I get time later. Hope this helps some1.

Attachment 46242

this is 1 I'm cleaning up and waiting on parts for. Holidays are making the mail run slow, but should have it built by Friday.I will post more numbers later if I get this 1 clean and a 47RE built.

A618 at the top and A518 at the bottom. notice cooler lines are different.

A618 on the left and A518 on the right.figured since I had the 2 cases apart at the same time I would post pics for those who don't know the differences

Sorry for taking so long on this. My HD crashed on my laptop and I have had to put all my backup files on a new laptop. Total pain in my A$$. I will try to get more numbers on here this weekend.

Thanks for pisting the data in December...I was relocating and missed it. I have seen the A618 on WITTRANS website, so I knew it was a variation on the 500 series tranny.

What does the 618 fit? Just curios.

618 is 47/48 R? trans.

The A618 is behind diesels and V10s. And yes they are either a 47 or 48 RE.

The A618, later 47RH (hydraulic controlled governor pressure) and 47RE (electronic controlled governor pressure), is a heavier-duty version of A518. It was used in trucks and vans starting in the mid-1990s. While currently used with some internal changes when coupled to the 5.9 L Cummins Turbo-Diesel and the 8.0 L V-10 applications, it's still a 727 with overdrive and stronger internal parts. It has an input torque rating of 450 lb·ft (610 N·m)

I finally got settled in Wisconsin and should have time in the next week to list the rest of the A518 and 618 numbers. I also have numbers for 45rfe and 545rfe. I have been asked several times what the most common problems I see in transmissions. the common ones I find are the check ball in the cooling line plugs up, driven too long with the front band out of adjustment, inner seal in the front drum piston is worn out causing the front clutch pack not to compress like it should and melts the front clutch and rear drum together, because they didn't stop driving it when it started giving them problems.As stated in other places most problems can be avoided by routine maintenance and always use ATF+4. Another question I get asked is where should I take the truck to get the trans serviced and how often. Any shop who will do the following things or do it yourself is my answer. #1- drain the fluid by removing the pan #2- adjust the bands #3- install new filter and pan gasket. #4 fill it up with ATF+4 ( DO NOT USE ANY OTHER FLUID IN THESE TRANSMISSIONS ,MAKE SURE THE SHOP ISN'T PUTTING IN SOMETHING ELSE WITH A FRICTION MODIFIER)
Have this done every 35K-40K miles and in between you can use a suction gun to swap out fluid. When you change your fluid by dropping the pan you don't get all the fluid out. I use a suction gun in between filter changes to suck out as much fluid as I can through the filler tube. Then fill back up with new ATF+4. You can buy a suction gun at most auto parts stores for less than $10. Oreilly auto parts is around $8 and then you just need 3.5 feet of clear rubber hose from the hardware store that fits on the end of the suction gun, but will still fit down the fill tube of the transmission. Slide the hose down the transmission fill tube until it hits the bottom of the pan and pull out all you can. Things to remember when doing this. It helps if the fluid is warm,not hot as the fluid gets very hot and yes even if you have a cooler installed. I have a cooler on mine and did every thing I know of to make it run cooler and it still runs around 155 degrees in the middle of summer.

Wow that's alot of information. Thanks for taking the time to post it. However I didn't see the part number that matches any on your extensive list.

Any ideas of what transmission this is?

What year/model vehicle are you driving?

I don't know what vehicle this transmission came from. It came extra with a 98 Ram I bought for parts. Since my original reply I've came to the conclusion I believe it's a 727 by comparing the shape of the pans.

If it has the O/D housing on it, that makes it a 46RE. Can you post a pic?

This is a 46RE 2003 transmission pan
Attachment 31225
Now this is the "main case" of said 2003 46RE and that smaller case is the overdrive unit case,which to my limited knowledge never came on a 727.
Hope this helps a little btw Good on you for searching for an answer

Truthfully I'm not sure if it has an overdrive housing. But here is some pics of it.

Hhhmmmm..... Could go either way. Definitely for a 2 wheel drive at any rate.....

What do mean it could go either way? Did the 727 ever come with an hole/slot for the crank position sensor? I believe I'm looking at a transmission from the A518 family 46re/rh not sure if 44re/rh came with the same bolt pattern.

44, and, I think, even the 42R? will have the same bolt pattern......

Magnum engines started in 92 (318), and 93 (360), I don't really know if they had the CPS on them at that point or not..... I shot of the whole trans might help.

https://cimg7.ibsrv.net/gimg/dodgefo...1c5b822358.jpg

Looks a lot like a 46R? trans. Check the connector (white) that sits on top of the valve body just in front of the rear cooling line fitting. 3 pin is RH, 8 pin is RE. RH will NOT work in the 96 and up trucks. It offends the PCM. :D

It has 3 pins in the white connector.

That makes it an RH, which will NOT work on your 98.

Thanks for all the help. I knew it wouldn't work in the 98. It's a 4wd. I bought that truck for a parts truck for my 99. Which is also a 4wd. The guy I bought the 98 from, had gotten it thinking it would work, discovered it wouldn't work and then just decided to sell the truck along with the wrong tranny. I don't need it, so I was just trying to figure out what it was so I could sell it.

Ah, ok, that makes sense. if it works, its worth a couple hundred bucks anyway. :D Money in my pocket NEVER hurts my feelings. :D

Yeah that's what I thought. Guy said it was rebuilt. I can't use it so I figured I'd just use it to recoup some of the $400 I paid for the truck. I was just reading on some other site..that the difference between RH & RE. H is for Hydraulic and E is for Electronic. So if that is true wouldn't that make mine a RE transmission?

Yep. Sure would. The difference is the governor. ON the RH versions, it is mechanical, with flyweights, and the whole nine yards. On the RE, there is a solenoid, and sensor, and it's all controlled by the PCM.

ok glad you all understand these codes so i am asking for help here. My transmission shows PK53007786 0785 9176 can you tell me what model and info that is? Its in a 91 W250 auto with a 360. Thanks in advance

Looks like its an A518 (46RH) without locking converter......

great. Thank you very much. Rookie question here but what does with locking/ without locking converter meann/change? It's a 4 speed including OD.

On some of the older transmissions..... apparently they didn't do the locking converter thing. So, no Torque Converter Clutch. TCC locks the converter, so there is no slip, it makes for a direct mechanical connection from the engine to the trans. (good for better gas mileage.) Not sure why they didn't put a locking converter in there........

So do I have a 46RE then??

Yep..

Trans identification
 

I’m dealing with a 2001 ram 1500 4x4 v8 automatic transmission. I’m almost positive I have a 46re but not sure since it is 4 wheel drive. Per your list here 4x4 models 1500-2500 year 96-99 have a 46re. Would I be correct thinking they would be the same?

Yep, if it's an auto, its a 46RE.

I have this transmission with a part number pk521184312642 3564. Can you tell me what transmission this is? I'm trying to replace a 46rh with this one if it will work. And or what will it take to get it to work..?.
