6 speed transmission fluid change

[Sandeep1994]

I changed transmission fluid today . Drain plug and fill plug are very easy to access both on same side ( passenger ) and lot of space .
I used redline . Its day and night difference in shifting .
1st to second gear clunk is gone and transmission shifts very smooth .
. Oem fluid from factory was not bad either but with redline Mt90 you can feel the difference

Hmm, interesting, thanks for sharing, what led to making the decision? Is it preventive maintenance or the clunk you mentioned?

Just normal maintenance . Truck have 30000 miles now so decided to do all fluid change differential ,Tc and transmission.
. Trasfer case and front diff fluids came out clean as new . Transmissions fluid was ok . I could have gone more without changing it . But rear differential fluid was bad when it came out .

Oh , maybe I need to do the rear diff then, I think I saw someone else reporting about the rear diff fluid quality
