If you followed the instructions regarding the getting the ATF to 80 deg C and going through the gears first with the engine running, then you should try adding ATF in small amounts as the instructions indicate till you get to the correct level. The question is where did the ATF go ?
You get P0700 with low ATF (among many other reasons, such as ATF filter issues.).
Also measure the ATF level with engine not running, after waiting fro the ATF to settle in the pan.
As per Mr Boca,
But if you want to do a service at least ,you could also drain and drop the pan , fit a new filter and gasket and check and replace the pilot bushing which could be leaking ,which is why the fluid is low.
Plus you would get some new fluid in the system, which would be a good thing , and then you can set the fluid level to the correct amount.
In my humble opinion, first of all neither of your cars are high mileage, this is 1
Second, before you get into as deep as Valve Body, Pressure Regulator Spring or Conductor Plate and since you donít know the history of neither cars and you just got a transmission dipstick, why donít you spend less than a $100 and get a filter&gasket kit, Conductor plate plug or aka Pilot Bushing or whatever da heck itís called and 12qts of Valvoline MaxLife. Do a Yumling method fluid exchange first, drive about 100 miles then drop the pan, change 3-4 qts of the fluid then filter and the bushing. Meanwhile donít forget to invest another $5-6 for a MAF or Electronics Cleaner, pull the TCM and watch for the traces of oil, if any clean the heck out of it. All this will cost you just about $100 per car then you watch from there.
Also make no mistake about 80C temperature, it is not the engine or coolant temperature as indicated on the cluster, it is actually the transmission temperature or transmission fluid temperature, so make sure you take a good drive before you check it for 80C. But usually if the initial fill is correct at 25C then 80C measurement comes right at the spot.
Check out in the stickies Yumling flush, I also added some pics there recently when we changed my mateís fluid.
Good luck and keep us posted.
Tomorrow we have a high/low of 64/52F. Not sure if that plays a part, but I'll try to drive for 25 minutes tomorrow and check again. I didn't think it would actually take that long for the ATF to reach 80C or 176F.
Or can I just do the cold check method first thing in the morning?
In any case it looks like the concensus is that I do the fluid change. Below is a list of the parts and the fluid I plan on buying. Please let me know if I have it right, if I'm missing something, or have any other parts or suggestions.
There is only one Valvoline MaxLife ATF if I understand correctly and it's compatible with my E320.
I would just double up on everything if I want to do the same with my E420? It's 10 quarts per car righf? I guess I have to buy 5-6 gallons of ATF... lol
Edit: I can do this fluid change with just car ramps right? I have a car jack and stands, but I feel more comfortable with the ramps.
Rule of thumb is 80*C is uncomfortable to touch. Pull the dipstick and immediately pinch the wet end. If itís not too hot to pinch, keep driving. I havenít caused myself injury if thats a concern.

Hahaha, I'll do that.
