About to go to mechanic, but need some help
So im having the transmission problem with the 98 320...i know there are hundreds of threads talking about this problem...and the sticky above shows all the checkups that need to be done.
according to the list, what are the major things i should get checked out? asking for everything on this list to be checked will kill my wallet.
most important and affective check-upss ( dealing with engine and transmission- nothing electrical)

Fuel pumps - make sure you got the updated version, check filter and lines to make sure they are updated.
Harmonic balancer- check it often. This has yet to be "fixed" on any year model.
D-pillar covers crack
Aux fan fuse blows- needs upgraded wiring harness and larger fuse.
Window switches - yer left front will go down and not come back up!
Defroster vent likes to pop out of dash, replacement is easy.
Door locks like to fail, jump up and down. replace latch to fix.
Oil consumption- check oil level regularly, use only mobil 1 0w40, change more often than required.
Trans connector leaks- new o-rings to fix- updated parts available.
Oil level sensor- make sure it works and doesn't flash low oil for no reason.
Transfer case shift motor - make sure low range light doesn't flash on start up.
Leaking canister shut off valves were still prevalent during '01.
Leaking washer fluid tank- still an issue to this day, even with updated parts.
Tail gate lock breaks, allows tailgate to open when locked. Replace outer handle assembly.
Sunroof wind deflectors break. Replacement kit available.
Catalytic converters break in half, or rattle. Replacement required. Must remove torsion bars and reset ride hieght after replacement.
Bubbling center console armrest- replace.
Seat side trim cracks, falls off - updated parts are stronger.
Tele aid- banner year for problems. Disconnect.
MCS unit- there are a number of problems. Updated part may fix.
Sunroof accordians fall off - glue back on.
Wind noise- test drive before you buy. Usually no fixing that.
Vehicle stalls when hot - crank position sensor failure. Replace.
Vehicle will not start - fuel pump.
Vehicle will start then immediately stall- replace keys or das module.
Self adaptations at limit, part load or idle, right or left bank or both - replace mass air sensor, intake duct seals, air filter.
Hesitation on acceleration- updated ME control unit will greatly reduce this issue, along with random misfires, runs like crap, etc.....
EGR fault codes- go ahead and replace the valve assembly and the EGR tube. Saves everyone a lot of trouble in the long run.
Lifter noise- replace all compensating elements, inspect cams and followers, replace as needed.
Vehicle won't start, already replaced fuel pump and or no voltage to pump. Check electrical connector on chassis near left rear wheel, and look for burnt connector under fuse box underhood.
SRS light illuminated- updated side bag connectors available, also seat occupied recognition sensor in right front seat has been a problem.
Seat heater does not heat evenly- replace heating pads, maybe seat cover?
Rear seats folded flat, now they are locked to the floor, can't get them up. - DONT EVER PUT ANYTHING UNDER YOUR SEATS. ANY OF THEM. Check to make sure there is nothing there before folding flat. Too many times the cables are broken or popped loose by a missing shoe or some doodad left under the rear seat.
Lower power steering hose blows off- recall in effect. Benz will cover this part for 10 years regardless of mileage. Install new hose and clamp.
Door insulation falls off, leaves gluey residue on windows and sunroof- remove, discard. Installing more just means it will fail again later. There are updated parts available, with mixed results. Its impossible to get all the glue off the door, and what happens when your new glue sticks to the old glue, which then fails?
Coolant flush every 3 years.
Brake flush every 2 years.
Air filter due at 60K
Fuel filter due at 60K
Spark plugs due at 100K
Dust filter and wiper blades part of B service.
Trans is filled for life, requires no service and there is no dipstick in the tube.
No recommended diff service interval either.
No recommended tranfer case service either.
Brake life varys widely by driver.
