Labor was saved and spent on beer. The first frustrating issue I ran into was locating the bung in the torque converter. I got about 4 litres out of the torque converter. If I need to replace that, will I also have to hoist the engine up an inch like its required for the engine mount removal. This was retrofitted sometime later.
The part number 126 270 44 77 can be used at a Mercedes-Benz dealer for ordering a replacement kit. But good point, and next time I'll do as you suggest, too; I just wasn't confident I was going to be able to get the plug out of the torque converter, so I finished the case draining and filter change, and then buttoned it back up before taking on the converter. I left the crossover pipe in place and was able to perform the drain of the torque converter. If you attempt this, expect a big mess even more than usual. I skated around the pool until the job was done and then mopped up.
I'm not trusting books or instructions. The factory procedure calls for removing the crossover pipe, and it's really not that hard - four bolts and it's off the one exhaust gasket can be re-used. Didn't see any evidence of blown seals above the pan sealing surface. What exactly does it have? It was painless except for the scalding fluid and fairly rapid. They have recently revamped their site so you will need to email or call. Thanx Dave he posted here on board sometime ago how good is this oil and my brand new tranny is currently with the Redline d4. It was 60k of light service though.
If you attempt this, expect a big mess even more than usual. Also, did you drop the trans pan and replace the filter? Remove 12mm hex screw cover. But the nuts on the opposite side of the flange. I thought it would be a good, illustrated reference for those of you who are interested in doing this job on your own. The Mercedes-Benz 4G-Tronic transmission was produced from 1981 to 1996 in 722. Amazing how much lint they shed. Use an engine oil pressure tester kit and connect the gauge to this port.
Just a reminder about Mercedes approvals. Anyway, I used the Redline High Temp stuff and so far it shifts great. The factory procedure calls for removing the crossover pipe, and it's really not that hard - four bolts and it's off. Simply click on the button below, and then follow the directions to prepare a complete and printable list of filters and fluid capacities for your vehicle. We recommend installing wheel chocks to the opposite end being lifted to prevent the vehicle from rolling. I have only had to rinse the pan with new fluid to clean any minor debris. Check your owner's manual for the recommended type and quantity of transmission fluid.
How is your R reverse on the transmission? Looked like leak came from the rear pan area toward passenger side. Great, now after visual inspection if the discs seems to be in good shape, which I doubt , I should pursue other possibilities like the pin. May or may not be good. Doesn't that supercede dextron 3, so I can use it? Also make sure there's a fill spout for the new fluid; some newer transmissions do away with traditional fill methods. I am doing the rear main seal and putting in the K1 shift kit, other than that I see no reason to open the transmission up as it has less than 100k on it with fluid changes on time throughout its life and no other issues. Global Transmission Parts is not liable for any errors or omissions.
No more frustrating and fruitless time spent in the owner' s manual. The part number for the gearbox is 140 270 21 00 722. Make sure the transmission pan and transmission mating surfaces are clean, and that the old filter grommet and transmission pan gasket are removed before installing the new parts. Interesting discoveries the next day made my decision on how to proceed with draining the 500E torque converter an easy one. Given the demands on the 500e transmission, it's a good choice.
I did not say to go inside of it. Lastly, don't cheap out on the transmission filters. Diff has been changed for ratios only, but usually Swepco 201 or Schaeffer. Throttle pressure cable adjustment: The throttle pressure cable tells the transmission when to shift. I am running it in that unit now and the consistency of the fluid itself is thinner so in an older worn unit it can cause some issues. Just trying to help ya out.
Changing the fluid in the unit with the Redline D-4 will be the next step after the minor front end repairs left tie rod and damper then alignment next week. Ever wash a window with a paper towel or rag in the bright sunlight? All information deemed reliable but not guaranteed. It is considered by enthusiasts to be one of the most reliable transmissions ever built by Mercedes-Benz with some examples exceeding 300,000 miles of service. This link also has a vintage vehicle lookup, along with a power sports oil and filter guide. I purchased mine at dealer cost. During the disassembly, make sure that the balls do not roll away and they must be inserted in the correct positions. I thought it might have a 129 part number.
