All new parts
I am getting tired of running a quarter mile and never having the brakes to stop. So I am finally putting on a front end disc brake conversion kit. I am sticking with the 6-lug design. I want the truck to be a sleeper. The only bad thing is when I go to a cruise in. No one ever looks at it until I rev it up, but by that time my foots to the floor and their starring at a cloud of white smoke.

Checking to see if you ever got the trans issues sorted out ?

Put the trans in drive using the shifter. remove the cable from the trans linkage lever. Manually shift the lever on the terans all the way down in low. Then move each detent back to the "D" position. The cable should line up perfectly with the hole in the trans linkage. If not, you will have to adjust the cable. Manual valvev position is very important in any automatic. You can also try adjusting in the "L" position,
by moving the ratchet shifter in L, and trans linkage in L, it has to line up without moving one or the other. Be sure to check park after adjustments, this is manual linkage as well,
try to push the car by hand to make sure the parking pawl is locked. Let me know how it works. If your using a TV cable from the trans to the throttle, this adjustment is CRITICAL for line pressure and shift points. Let me know how it works.
That's close to the limit of a 700R4 - the weak link is the forward drum which sounds like what let go. No one I know of makes a hardened drum. Looks like your going to have to take it out and inspect the forward drum and surrounding components like the sprag clutch.
If your looking for an overdrive unit and no computer, the 2004R is a better unit with less RPM drop between gears.
Of course you need to find high performance parts for these units as well. Some of the twin turbo buicks are running these units with 1000 HP. Of course the budget always dictates your direction. If an overdrive is not your main direction, turbo 350's and 400's if built correctly, can withstand 600 horses without fancy aftermarket hard parts other than sprag assemblies and good clutches and steels, with clearances set correctly. I have been working with automatics for almost 30 years now and would be happy to give you info on my experiencees.
