Hi,
i am hoping you could give me a bit of advise. I am the 2nd owner of my 97 e320 with 113k miles and within the last 3k miles the transmissions started to shift hard. It shifts hard from 1st to 2nd only when reved over 2500rpm same going from 2nd to third and if i drive very slow keeping the rpms down it shifts smooth and rest of the gears are all smooth. I should also mention that when it shifts rough that i hear a clunk sound from the engine area. Does this should like a specific problem with my transmission or more like a timing or motor/trans mount problem? Should I do the following or just take it to some mechanic or dealer for service? thank you.

here is what im planning to do to address this:
1. replace the trans fluid using MB 722.6 fluid
2. replace the shift linkage bushing, mine is definitely worn out.

questions:
Since I will have the trans open should I also replace
1. 722.6 Pressure regulator spring replacement - spring with Sonnax part number 68942-01.
2. what spark plugs should I buy?

items I need to buy.
Fluid = 65.00 (6 @ 10.67ea)
Cap / Safety Clip = .88
Filter Kit = 15.54 (filter & gasket)
Drain Plug = 1.91
Copper Drain Plug Seal = .20
Dip Stick Tool = 45.00

I live in NJ and would love to hear your opinion.

thanks again,
Sunny
