Just to update,
I've completed the transmission fluid change. It went real smooth and everything looks great. I'm road testing it today.
I think that the previous mechanic was very responsible. So far I have not found anything that indicates any short cuts. There was fine particles around the magnet, the filter was clean and only very very minor fine dirt in the pan.
The fluid was not pink but I have seen much worst on the web. As soon as I get time I'll post some images. The filter came out with the o-ring, so I didn't even have to go fishing for that.
The only tricky part was the bolt on the torque converter pan that is above the starter. What a pain. The previous mechanic did leave it out and I can see why
It was a standard 5/16-18x3/4 long. The original bolts had a reduced head but there was room enough for the standard head on a standard bolt.
I used NAPA premium performance ATF
part number NP-75203; 5 gal bucket
The label claims for use where
dexron, dexron II, dexron III, mercon, and allison C4 is recommended.
I have about a gallon left so I'm wondering if it can be used in the power steering. I've seen conflicting reports. I haven't been able to find a manual for my year to see what is recommended.
I'll post some images later,
thanks to everyone for their advise and support.
