I have a 3000 series transmission with a 4 inch sump filled with TranSynd. When I have the filters changed this summer I plan on using the fluid analysis. Since the filter change results in the loss of 10 quarts and the transmission holds 29 quarts I am replacing 1/3 of the fluid. Should the oil for the analysis be taken before or after the filters are changed and the new fluid added?
Racerchaser,
Purchase an Advanced Oil Analysis Kit and take a sample first, before you do anything else. Send it in right away for analysis and wait for the results. Then, if the fluid shows to be good, you can catch it in a "clean" bucket (and I do mean very clean) and put it right back in again after you change the filters. There's no need to top it off and throw out good fluid. Be sure to check the level at operating temperature after you've finished installing the new filters and you'll be good to go.
How's that for a "good" answer !!!!
