FYI, I talked to the owner of http://www.bowtieoverdrives.com/ a while back at a swapmeet, and he said 75% of phone tech support calls are for the TH200-4R transmission vs. 25% for the TH700-R4. And his sales are 80% 700-R4 vs. 20% 200-4R. He says 700-R4 are easier to install/set up, but people want the 200-4R because of the "better" gear ratios, which he says you really can't tell the difference. He recommends the 700-R4, if you decide to go OD.

Thank you for taking the time to count the ratio and post it.

Now just to stir the pot a little more, here is what GM thinks you should have in there.
http://chevy.oldcarmanualproject.com/shop/1959_60/...

So is GM wrong, or did they just fail to mention that a buyer could order an optional ratio If it's a gear they already have sitting on the shelf, the cost would have been minimal, perhaps even free.

Ray



I'm going with GM is wrong

Ok so here's what I've done so far.
Also took some picture of starter holes that some have brought up.

If I counted the number of teeth on the flywheel, properly then I have 167.

The overall length of the transmission is around 125", including a 5" tail shaft.

Now I realise I will need to do something about the torque lock-up so between the 700r4 and the 200 4r is one easier than the other?

Could someone answer something for me about the governor on a power glide.

I've taken pictures of the governor itself and some information from the 58 shop manual.

It seems like there's suppose to be a gap at the top and bottom of the valve. If you look closely there doesn't seem to a gap at the bottom and the one at the top measures 35 thousands of inch.

Can someone explain how this governor works besides the fact that it controls pressure. It seems to me that there should be a flow from top to bottom...other than that I'm lost

Figured out how governor valve works. It was stuck so I cleaned it and now it's good. I did find some dicolouration though as if it got hot...

I also discovered the throttle valve is broken..

Found sludge and dirt...

Also found the pin that drives the rear pump was broken and messed things up in there pretty good..

Ran out of room....

Here's what the rear gear pump driven gear now looks like.

It's a wonder the darn thing ran at all..... and I paid for that...

Ouch! The drive pin is fairly easy to find. The shaft looks like it may needs repair though. Maybe weld it up and re-drill. Might find the pump on eBay
