I have used DACCO, but they have discontinued the older 722.3-722.5, yet I'm getting ready for full rebuild 722.5 on a 95 SL320 which lost reverse, and I will using TransTec Kits, and RockAuto sells the overhaul kit(gaskets and seals) for about 80bucks, and they have the Banner kit with gaskets, seals, and frictions for about $190...

TransTec Authorized Distributors - United States

When you look-up your car on the RockAuto site it will have the name of another company, but that is the distributor of the TransTec kits.

When you loose forward gears 722.3-722.5 more than likely it is the B2 bore piston seal which is on the outside of the transmission...

On the 722.3-722.5 transmissions, the identity markings are on the rim where the oil pan butt's-up to the transmission. I cannot remember which side, but it is either the left or right side. The numbers are stamped which have the model number and tranny serial number...

Hi, i am new at the forum here.. I put my MB 320ce in the garage a few years ago due to that the car all of a sudden wanted to go in reverse when in reverse and in neutral and also it has a "war" in the drive so my car wont go forward before i push the petal. I have through the 4 years tried to read about the problem but realy never started working on it due to lack of money but now is the right time. Is it possible that this can have anything to do with the valve body. I changed oil and filter before i put it away. My transmission is a 722.503. Any ideas and input would be greatly appreciated! I love this car and had it for 12 years. Sincerely Per Martinsson

 

Good effort Benzoind. I am yet to rebuild a valvebody.

 

Tranny is a 722.508

Welcome to BW. The slow.no reverse problem with the 722.3/4/5 transmissions is well documented on this forum. Has nothing to do with the valve body.
Transmission has to come out and the offending seal(s) replaced.

 

Can you please send me a hint on how to find those threads, i am from Sweden and have a little bit difficult to find where the information on these problems are found.. Thank you! Appreciate all help!!

 

This should give you an idea:

Gearbox 722.368 repair manual / tips

My gearbox went totally black after backin up with R. D/R does nothing. No drama (noise, chatter, clatter) was involved before brake down. Now the GB is taken out and because only 115 000 km i would like to repair it. Does somebody have access to 722.368 model gearbox repair manual?

The referenced thread is for 722.3 and you have 722.5, which is the same with the added 5 electrically controlled overdrive

BTW, the BenzWorld search engine is up on the top of the page (the window with the little magnifying glass)
