1995 GMC transmission went south yesterday

[Jeepwm69]

Was driving home from the city yesterday with a new water heater, and noticed the truck started revving a little and didn't seem to pull as well. Progressively got worse and worse, and I knew the transmission was going out. Checked fluid and it was full but burned smelling and dark. Ended up having to get towed in the last 20 miles to the house.

So, I know the 95 is kind of a transition year between the 700R4 and the 460 transmissions, so will have this one rebuilt. One place has quoted me $1250, and waiting to hear back from the other. Not a lot of reputable places in the boonies where I live, but the places I've asked have been recommended by shop owners/racers.

Truck only shows 70K on the odo, hardly any towing since my grandfather bought it 20 years ago with 35K on the odo. Added a transmission cooler several years ago, but fluid hadn't been changed unless it was done prior to the truck coming into the family. I had a load of Mobil 1 ATF with plans to change it when the weather got nice this spring, but guess I waited too long.

If I have this bench built what is involved with getting it back in the truck? I'm a manual transmission guy so not much to screw up there other than getting the clutch play right. I assume I'd have to adjust the shift cable possibly, or will this thing bolt right back in?
