Who are like the top 5 GM Derby transmission builders ? Also side question, can you eliminate the converter and still have fwd/revs without a clutch pedal?

No, you can't eliminate the converter. There'd be no way to convert the power from the engine to the transmission. Circle track cars use a drive that bolts to the crank between the flex plate and trans that drives the pump. So yeah you can.

Yeah, I know they have them too, but in our sport, it's impossible to use.

Circle track cars use a drive that bolts to the crank between the flex plate and trans that drives the pump. So yeah you can. yeah that's right but they have a lever/clutch (really a fluid valve) to get going in first and then go to second (powerglides), but they were doing that 20 years ago? Just thought some new tech may have emerged since then? SO back to my main question then, who are the best Turbo 400 builders in the country for Derby?

I have a th350 rebuilt about 6 derbies ago. It works great in my yard any time I want to go fire it up but 3 times now when I've trailered the car for a couple hrs it wont move when I try to back off the trailer. Acts just like one that is several pints low on fluid. after a couple of minutes it starts working and really works well throughout the whole derby, no slipping etc. The fluid is nice, doesnt look like anything has burned and it measures full when it's acting up. I'm guessing something is sticking in the valve body? I forgot it did this which is why it happened a second time and the third time I expected it but just hoped it would work and was lucky it did. I thought I would have it pulled out by now but the car just wont die so I am probably going to try it one more time. I would swap it out but I dont have a spare since I normally run mopars and am clueless how to fix a gm. Any thoughts?

Question for you guys who know transmissions. I have a th350 that suddenly started going forward (drive) in every gear. Park, Reverse, Neutral every gear pulls forward. The shifter linkage clicks like it's changing gears normally, but all I get is drive. Fluid is clean and it pulls fine forward. I'm assuming it's somewhere in the internal shifting linkage, but I am not exactly transmission savvy. Any idea what I should be looking for when I pull the pan?

If it were a mopar I'd say a band broke/stuck but not educated enough on these to tell you much else

It could be that the little s clip came off the plunger in the valve body or the nut backed off the shaft inside the trans.

They have a lock up for the convertor the 4 prong plug on the side. It's not necessary but having the throttle valve cable set right is a must.
