Go ahead and change the fluid, but do a few drain & fills with a few weeks of driving in between to slowly replace the fluid and do some gentle cleaning. Replace the crush washer on the last drain & fill. Torque spec for the drain plug is 22 - 29 ft/lbs. Better yet, do a
pan drop first then a couple more drain & fills.
I've been reading those lines very carefully so I don't mess up my transmission. I just bought my Pathy with 172k and I'm not sure if the AT fluid has ever been changed hopefully it has. When you recommend to drain and fill, you mean drain all that can be drained on one drain (sounds stupid but should make sense) or to stop it after a low amount of fluid falling? I suspect the first, because one drain only removes a portion of the fluid unless it's being flushed. Am I right? According to your instructions of a total of 3 drains, would each drain remove around 1/3 of the total fluid capacity?
So, it would be:
- Pan drop with one drain and fill, replacing filter and pan.
- A couple more drain and fills with a few weeks of driving in between, replaing crush washer after the last drain.
I'm concerned because I don't want my transmission to be affected by a total replacement of fluid via a flush in case it hasn't been changed in too long. It doesn't really smell burnt.
Thank you for the info Towncivilian.
