reverse is a weak point in these transmissions. The frictions are probably worn down to metal and the piston needs to over extend to apply. I replaced these frictions on my 199 blueblack 300e24 when I first got it. Id be replacing the piston seals also. The reverse is on the back of the front pump and not really a hard job. The removal of the transmission is the hard part.

on my 2 cars yes, this blue 300e is yet to have any significant money spent on it yet but it will come. Engine mounts are a piece of cake as long as you can lift the engine

@@MMWA-DAVE thank you for the answer!

off camera i did test the metal chips, 50,50 mix of ferrous and non ferrous metal, so dead give away its reverse nearing end of life. Don’t need to buy anything from burgsma, can source own neodymium magnet to put in the pan if required.

Mag Plugs in a Trans are a waste of time anyway, Note the detritus sitting on top of the filter and in the riffles in the trans pan? Mag Drain plug wont make a difference and the other issue is Non Magnetic particles. If you insist on using this panacea then a good rare earth magnet on the outside of the trans pan will give a fair indication when you pull the trans pan and nothing beats a Pan off filter change and service either DIY or Professional.

I stuck some hard drive magnets in the pan of my 722.3. MB fitted a magnet in the pan of some late 722.3 / .4 transmissions, you can find it in the parts catalog under the G Class.

@@MMWA-DAVE how about Magnetic Inline fluid filter?

front tranny pump spins at all times engine is running. Rear Aux pump on early trannys like ours for push starting only operates when the output shaft spins

@@MMWA-DAVE You probably know this, but the rear pump was deleted for the 1991 model year!

@@compu85 yep, i remember reading that in the transmission manual. I’ve never tried the push starting would be interesting to see it work

@@MMWA-DAVE I've done it once on a W123, you have to get the car going fairly quick... about 20 mph. Go from N to 2/L on the shifter!

@@compu85 You have spam bots commenting on your apple lisa video waffling on about some website replying to my battery comment. I always report and block the spam bots, you gotta keep on top of it or they take over completely

blown exhaust manifold gasket makes repeating noise. Still needs replacing

I made a video of it when I got it. It’s ok for general maintenance tasks but because center is not open its no good for exhaust or tailshaft work. I can’t recommend it for rear wheel drive cars and will probably sell it later.

@@MMWA-DAVE Understand. THNX!

I used to do it without one, its not bad on jack stands. you do tend to get ATF all over your arms, face and in the hair though! you can get around this by letting the transmission drain into a large pan over night. (with pan removed)

have a look for the correct part number and once you have it you can generally buy them from online sources. Or do as tim did and just rebuild them with new high quality hydraulic hose and top quality hose clamps. If you want to retain the crimps you can have a hose specialist rebuild them for you. The hose likely will be better quality too.

@@MMWA-DAVE do you know a good website where I can find the part numbers? I have been looking without succes.

i have a portable scissor lift i purchased locally. Its not ideal, best only for basic services and brakes etc. I will get a better one in future

I’ll copy the link of a post on Benz World which has a larger description here. This particular example originally brought a 722.501 but blew as these tend to do (apparently), and was replaced with a 722.358 -I guess - from a 300E. Just a week of ownership and found a puddle under the car. Not sure if a seal or line gave up or I hit sth. Topped of with Valvoline ATF Dexron III (Dex/Mercon) but still have to control the leak and find a solution briefly. www.benzworld.org/threads/just-picked-up-a-w124.3073729/

one costs $1.50 a can the other $20 here anyway is what i was getting at.
