Flexfer Posted August 18 Share Posted August 18 Hello again, I am unable to resolve this issue; but, how can I ascertain the appropriate amount of ATF required for my transmission? If I immerse my dipstick into the tube before to a drain and refill to the same level post-drain, how can one ascertain the accuracy of the amount? The dipstick I have ordered is an aftermarket model with increments of 10, 20, 30, 40, etc., however it provides no useful information. I cannot just pour in 6 or 7 liters and assume that is accurate. Does the authentic Merc dipstick possess the accurate high/low measurements, or need I consult a dealer for proper measurement? Any feedback is once again welcomed. Thank you 04 C180K 722.6 Box Quote Link to comment Share on other sites More sharing options...
DMGRS Posted August 18 Share Posted August 18 They possess a designated threshold for low temperatures and a distinct threshold for high temperatures. It is essential for the dipstick to be of the appropriate length. Quote Link to comment Share on other sites More sharing options...
DMGRS Posted August 18 Share Posted August 18 1220 mm seems to belong to you. Quote Link to comment Share on other sites More sharing options...
Flexfer Posted August 18 Author Share Posted August 18 Thank you. Assuming it is the proper length, should it register between 10 and 12 degrees? I should verify that it is 1220 long, since I recall seeing a measurement in the 900 range, despite it listing my wagon. Quote Link to comment Share on other sites More sharing options...
DMGRS Posted August 18 Share Posted August 18 The temperature influences the levels, which fluctuate when the oil undergoes heating and cooling owing to expansion. Ensure to transition the gear selector through each gear for 20 seconds, commencing and concluding in the park position. A scanner would also provide the temperature of the automatic transmission fluid. Quote Link to comment Share on other sites More sharing options...

Flexfer Posted August 18 Author Share Posted August 18 Indeed, I should and will likely need a scanner at some point. For the time being, I will use a temperature gun to target it. Quote Link to comment Share on other sites More sharing options...
norbury.brook Posted August 18 Share Posted August 18 The length of the dipstick is irrelevant; the black triangle at the top of the dipstick's plastic part encounters a limit above the gearbox sump, enabling the black measuring section to ascertain the fluid level from above. It is customary for a significant portion of the dipstick to protrude from the dipstick tube inside the engine compartment. The ATF level is assessed while the engine is running, in park, on a flat surface, after a 30-minute drive when heated. Quote Link to comment Share on other sites More sharing options...
Flexfer Posted August 18 Author Share Posted August 18 Thank you. I was concerned that a shorter measurement may provide inaccurate results, but I appreciate the clarification. It may take several days for it to reach in New Zealand, at a minimum. Quote Link to comment Share on other sites More sharing options...
