sweet!!

if you have ever seen the 4th gear clutchs, you would understand how they are so weak and go out all the time.

Yep, they look kinda cheesy. Stock transmissions are definitely a compromise, people complaining about a firm shift don't do clutches any favors either.

So you're saying that firming up the transmission's shifting will cause additional wear on the clutches? I thought improving shift firmness, within reason, would reduce transmission wear and lower operating temps.

I'm saying just that. "Normal" people complain when a Trans shifts firm, so out of the box GM has them shifting soft, which hurts longevity.

I'd bet they would on average last longer with a mild shift kit and a vette servo.

I haven't given modifying the transmission much thought. I assumed the deeper pan and OEM cooler would be adequate to pull a car using a tow dolly.

Trans is in the truck, and all I have to say, is HOLY ****. This thing will break your neck off when you put your foot in it, and the circle D stall should have been what GM put in these things when they were new. I love it. I have a little trans tuning to do, mostly returning shift times back to stock so I can change from there, but overall I am very happy with the combo. Feels like a totally different truck.

Oh, and for the guys that may be freaked out by Vacuum Modulators. Don't be! The shift pressures are f'n spot on for a nice built unit and they are completely foolproof. Very docile when driving around town, and nice and hard when you're beating it like a circus animal.
