I put in Mobile One Synthetic ATF Mercon in the transmission yesterday. It reduced the transmission noise and made the shifting smoother between the 1st to 2nd shift. I would highly recommend this for anyone having the shifting problem or excessive tranny noise.
There is a plug on the passenger side close to the cross memeber. I used a hand pump to get the fluid in there. Took about 15 to 30 minutes to pump all 3.2qts in taking my time.
