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

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.
