Transmission rebuild - PeachParts Mercedes-Benz Forum

Hi guys,

My 1990 300E (177,171 mi.) now takes about 5 - 7 seconds to engage reverse gear - which can be scary at times. (Seems to take longer when I am backing uphill). Shifts into first sometimes are harsher than they had been in past. I believe it may be time for rebuild. Fluid (Mobil 1 ATF) is good, fluid & filters (treans pan and torque converter) are changed on schedule.

I would prefer to get rebuild vice news trans. for cost reasons.

I have done most of the work on this car since I bought it, but I think trans will take me a very long time, if in fact, I could do it.

Sooo, the question of the day is: Does anyone have a recommendation for the best Mercedes transmission rebuild man in Atlanta (preferably North side of town) area?

Thx

Unfortunately, the MBZ transmissions were technically archaic and of mediocre durability at best. Front oil pumps fail, and the reverse clutches always go out too.

Before deciding on a rebuild, get the tranny properly diagnosed--checking the operating pressures is essential to determining the condition. There is a small restriction orifice in the valve body for the reverse gear that can plug and slow engegement down too much. A simple valve body remove,clean,reinstall MAY be all you need.

Where did you end up with your tranny matter? Did you buy a rebuild?

Hey Lino,

Have not yet addressed issue, as, if I baby the trans, it does fine. I still need to do something long term, but have had other issues that have delayed me.

Well at least you're lucky enough to be able to drive your car in its condition. Mine stopped in the middle of a parking lot and I had to get a tow. I got the new transmission now finally and it seems to be working fine considering I only drove it once which was when I drove the car home after finishing the repair.
