Making progress but have had 2 disc brake hold off valves that leaked out the back. Third one is on the way.

Th-400...
 

You can drop the pan with the tranny in the car...have your shop check the valve body to see if a shift kit has been added. Converter can be swapped without completely removing the transmission. [check the flexplate and make sure it is in good condition]

You can also upgrade the governor without a tear down. A remote cooler and deep sump pan are also simple upgrades that will help extend tranny life.

ATI is a good source for th-400 parts and advice.

That seems to be the problem with some repop hold off valves. Had the same issue with one I bought. Had a 70 NOS style on my 69 Camaro, wanted the correct 69 style, installed and started to bleed the brakes. Of course, it leaked and didn't stop, so I reinstalled the 70 style back on with no issues. Nothing like the original parts.

Third disc brake hold off valve is working. Lets hope it continues to work.

Thanks for all the tips - it helps

I've noticed that in the NEW gauge cluster - the tach red line does not match the red line in the original gauge cluster

Were some of these red lines different on the original clusters - early vs late - or is this just something with the re-pops

Why did you replace the original gauge cluster with a repro?

Because the fellow helping me stays right busy - I could get a repro right fast and him get it installed - instead of waiting for mine to be shipped, repaired, and returned.
I can still get the original repaired now with more time.

Not a bad strategy to get the car drivable and enjoy it while waiting for items having a very long lead time. As long as $'s are there, it makes a lot of sense. Clock ticking for us older guys. :-)

That ticking clock makes me wish at times that I had just bought a nice (not over done) car - but there is also the satisfaction of getting this old car usable - so it can be enjoyed.

But I do have a couple more cars that I am already getting to enjoy - I'm blessed

Nice job Tom! Love what you are doing!
