Removing Auto trans from 4.4, couple of questions

[fmugur]

I don't have to do the transmission yet but I have to top up the oil. The ATF Fluid Top-up Procedure pdf file is not longer available.
Can you post a couple of tips on how to do that. I know you have to bring the temperature up to 40C... but how much you have to add?
thanks

FM,

Here is a good thread.

In the AT part catalog there is a section on this as well. If you PM me your email address I will send a pdf of the parts cat.

Good point, next time I will have a look how they say it on the bottle.

Great post TriX5. I learned enough to make me really dangerous.

Checked again and JCL is right. It says: "Also suitable for.....etc". I would not use it in mine.

Here is an easier way to fill your transmission and differentials than pumping it in. I bought this contraption at Advantage but Pepboys also has them. It comes with a foot of hose but HD sells the same size hose in a 10 feet length which I added to mine. They also come with an funnel but I decided to go with this one and attach a water bottle. If you take the white adapter off it fits an oil bottle.

I cut the bottom from the bottle and hung it upside down from the garage door rail. The cap at the bottom makes the spilling less when you take it out and it has a valve at the bottle side as well.

String the hose through the passenger door handle and over the top of the exhaust and use a tie-wrap to attach it to one of the big nuts that holds the heat shields up. Then dumped the fluid in a liter at a time.

hey, TriX5

Im tackleing the same project...I read that to get to the top bolts on the tranny did you remove the inner plastic firewall in the engine bay then have access to the bolts?

Second question, i see the cover for the torque srews after you remove that it says to use a special bmw tool 24..... it a magnetic socket but i was wondering how did you remove the torque or i mean seperated it from the engine i know it uses 3 bolts to made with the flex disc.

third question: do you remember which repair kid did you order? i have 155K and have had one oil change was about to do another when TC went out so i have an excuse to remove tranny but not the time to tear it open and rebuild it or ill see whatever ill figure that out...mainly i was wondering on the kit you ordered i saw a lot of kits ie master kit etc with clutches etc plust there the valve body kit too.....


TIA

Yes, best to remove that piece and get the top bolts out that way. They are different from the others in size.

To disconnect the TC from the flex plate I used a regular socket but has to thin wall. Impact sockets probably would not fit. 17mm IIRC.

You need the manual, otherwise it is a bit confusing. I got the over haul kit, the clutch disks and the valve body kit. I also installed a new bearing in the output section, runs much quieter now. Check your radial bearings and at least change the A/B clutch bearing.

Once you have the AT out, you absolutely should do the overhaul. The o-rings get very brittle and once one of them breaks you get slippage on the clutches.

Good luck!

Yeap looks like my bearing also failed like you said. I looked into the hole and i saw the movment of on of the peices. I didnt see any debris in the oil. Ill pull the pan off of it tonight and see the filter. I am going to assume if i dont find anything just small fragments. Then i should just like you said get the overhaul kit and clutch disks (if nothing wrong should i change?) Ill definitly do the valve body kit. oh also do yo have to replace the oil pan bots?

Curious where did you buy your kits from? Im on the cobra transmision site and they have a number of kits available...

The guys from Eriksson were very helpful for sourcing the kits but could not help me with the Tq Conv. I think best way is to have it remanned by Transtar or some other reputable shop.

Transtar Industries, Inc. - Torque Converters

Transtar also sells the fluid you need to refill.

There are some other threads by RDM08 and CivDiv that should help you do this.

I did not change the bolts of the pan but they are very soft so maybe get a handful of spares?

I would change the clutch disks at any rate. They do the hard work and once you are in there it is easy to exchange them for a new set.

Make sure that you give the bolts holding the F-clutch to the back of the housing a tap on the head before trying to undo them. See RDM08's thread.

Hmmm thanks TriX5,

My only issues is I have the 5L40E GM tranny and i can not find any one selling any valve kit...Just the clutch pack etc which is all great but i read that this tranny as ive read in many posts on here the reverse eventually fails and some pple are stuck with no reverse. The problem is not the gear but a failed part in the valve body. But so far i cant find parts for valve overhaul yet. if anyone has worked on the gm tranny specifically the valve body please chyme in?
