My next question is about changing my Allyson fluid. When I install Transynd Synthetic ATF which will replace my Dexron 111 ATF. I don't think this change will completely replace all of the Dexron so how long should I run the new Transynd before I change it again so that the remainder of the Dexron will be flushed out.
Ed,
Here's the procedure that I recommend for everyone. I believe this is the best possible solution. You really want the old DEXRON-III gone as quickly as possible in order to get all the benefits of TranSynd. Any old DEXRON-III continues to thin out and, without knowledge of the current condition of the fluid, it's best to just do the back to back changeover.
PROCEDURE:
- Drain old transmission fluid
- Change the filters (lube and main if transmission is 3000/4000 Series); spin-on (if transmission is 2000 Series)
- Install fresh TranSynd and check that fluid is in "Cold" band on dipstick
- Drive for 1/2 hour to warm and circulate the fluid
- Drain mixture
- Install fresh TranSynd and ensure that level is correct with transmission in Park, engine at idle and vehicle parked on level surface.
I do recommend a fluid analysis once a year on the transmission to ensure against contamination. Hope this helps. Arch Hoagland asked me to give some input.
