What's the trans fluid change procedure? I have the pan gasket and fluid. The trans has no drain, where is the fluid added?
Also whats the correct procedure and tools necessary to get to and change the upper O2 sensors. The drivers side access is very limited.
I also want to change the plugs, your suggestions to help with access and procedure will be greatly appreciated.
I am mechanically inclined with a fairly well stocked roll away.
Thak you in advance.
Do you
have the same problem?

As far as the trans fluid goes, I went to M/B and purchased their universal dipstick for their trannies, it wasnt cheap (around $60) but I can now check the trans level on their vehicles. If you arent into buying that, you could drop the pan (catch all fluid) and measure how much came out with empty liter bolltes and replace that amount. No drain plug means a messier drop of the pan, some have one some dont. You should only use M/B trans fluid as well. As far as the tune up goes, I usually unbolt the coils from the V/C to move them out of the way for more room. If this one is COP (Coil over Plug) then you just pull the coil and the plug is right under it. These cars arent hard to work on, just different. O2 sensors can be abear, there are wrenches made just for getting to the o2s on cars like this, you may also want to try a 7/8 crows foot on a ratchet, sometimes that will get you in the tight spot
