Metric 200 lock up trans?

[Jeff Stout]

Can a regular 200 be converted to a lock up design? If not how can you tell from the outside of trans that it is a lock up style.

200 lock up will have an electrical connector on the rh side just above the pan rail and the input shaft has a no splines protrusion beyond the splines with an o-ring.

Are any Lock up TH 200's legal in Stock Eliminator?

You could use a lock up case for any year, but a functioning L/U would be legal in '81 or newer cars.
Of course , adding that weight to a SB converter, would be a wash, at best, IMO


Edit..Jim Mantle: That would be the LH side (driver's) behind the shift shft, unless you had it in a clamp fixture in front of the bench ;-)

I think some of the fast guys are probably running lock up convertors along with steep gearing and a 7 or 8 inch convertor but you're not going to get them or anyone to talk about it..

I stand corrected, had to go out to the shop and look. Often thought of trying a lockup in the Pacer, legal if I run it as a 79.

The lock up trans if I understand correctly has the tag on the side that is labeled 200C--- also if you look at the input shaft you will see a small straight shaft on the very front appx 5/8" Dia and 1-1/4"long

Can a race transmission be built out of a 200C that originally had the lock up converter? They are not as hard to find as the non lock up torque converter TH200 units.

I was informed and shown by a former GM transmission engineer that the TH200, Oldsmobile diesel engine powered cars have a beefier case. He had both a standard gasoline engine case and a diesel powered case next to each other. The diesel case was beefier and thicker and also has the universal bell housing pattern. The diesel case was also heavier.

Yes.
Some guys like the earlier pump design in the non-L/U model, and some like to use as new as possible.. I never saw much difference, and have built plenty of both styles.
