Type A is for cars from the 50s. Type F is good for your power steering sytem, and Mercon III is for the trans.

Stay calm, you own a 21 year old Mercedes Diesel. Its going to need constant love and attention to keep her happy, so just pay attention to her and keep her well maintained. They have issues like this from time to time. Maybe if it did have a rebuilt trans put in, you can ask the PO for the shop info. Perhaps they put in a defective seal?

You need to ditch that old slushbox automatic and get yourself a nice 4-speed manny tranny.

i cant drive stick and the traffic by my house it would suck..

so the p/o's screwed up. .they put Type A... i went to dieselgiants site and saw he uses mercon dexron III... and brandon said changing fluid type in the tranny is not a good idea..it likes consistancy

there old mechanic recently died of old age

try adding a teaspoon of motor oil to the tranny. alot of times it will help swell the seal. afaik you can pull the tranny and do just the front seal.

Hold on...slow down!
You do NOT need to rebuild the entire tranny over a stinking seal leak.
If the tranny works fine otherwise when it is filled properly then just let well enough alone inside of it. You will need to pull it out (very simple to do) and replace the seal, which can be done without opening up the insides of the trans. Although they are harder to find, tool suppliers make seal pullers that resemble a small hook, with a tang off the side for striking a hammer on, so you can hook the seal and tap it out without opening the tranny up. I know for a fact that MAC tools makes them. (I own one) While you have the seal out look at the support bushing with a flashlight for damage or excess wear, in worst case you might have to pull the pump off and have a new bushing pressed in for a few bucks at a local machine shop. Also be sure to check the torque converter stub for the same. Make sure you seat the torque converter all the way in when you reassemble, by wiggling and rotating until it seats back into the housing where it was before you removed it. You do need to address the seal though, to assure you don't create any fire hazard issues with the exhaust system and oil, and also because if it blows out all the way it could potentially cause enough pump pressure loss/rapid fluid loss to disable the car.
