The 73 I pulled it off of had it mounted in this same location and position, thats why I chose it.

4L80 was much to expensive to think about, a core is around 1k here, for the price of corr/rebuild I could buy a gearstar trans.

The 4L60 will be built enough to handle any extra power I out on it which I dont plan to do for a long time. Never had an issue out of a 4L60e in any truck Ive owned even with upwards of 300k miles, only time I seen someone have an issue was when putting more power on them or rrally dogging their trucks.

Will have trans built for more than stock hp/tq just to be safe. I am mostly wanting reliable driveability in an old truck, so stock power in this light of a truck will likely be plenty for me.



Hopefully by the end of the year I will be driving it, going to need glass before transmission I think, dont want a cab full of water while sitting at transmission shop. As soon as a transmission is put in I can move it around the yard though.

The prop valve doesn't know what position it's in & works either way.
On some vehicles they're mounted fore/aft; others might have them left to right. They're mounted based on the packaging of the various components & placed where they'll fit.
