auto transmission for a 1966 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Rstone · 09-14-2005, 12:01 PM

I have a 1966 Chevy LWB with the original 6cyl engine
Has a 3 on the tree. I need to know what auto trans will bolt up and also what to do about the steering wheel. I want to keep the 6 cyl in the truck.
Also would like to put power steering and disc brakes on this truck.
Any help will be appreciated.

welcome wilson oklahome. For power steering and disk brakes fine a 73-89 (to 91 on sub) crossmember it bolts in just 4 holes to drill easy. then buy a rez ps adapter. hope that helps

The powerglide would have been the original trans. I think a TH350 would bolt up, as well. For the steering wheel, I think you should go with one of those welded-chain jobbies

I have a 66 i6 with a 350turbo on it.

I was wondering if a 700r4 or some type of overdrive trans would bolt up to these 6 cyl motors.
Also meant to say steering column instead of steering wheel in my first post. Thanks for all the replys

My first truck was a 66 GMC with a 250 inline and a three speed. I did the power steering and power brake conversion it 20 years ago. Back then they didnt have the PS box adapter back then, so that will make it easier. I used a power steering pump from a mid seventies nova. It all bolted right on, but dont forget to grab the alternator mount that bolts to the block, its a little different. the back of a 230, 250, 292 block is the same as a small block chev, so all smallblock trannys will work. The 65 that Im doing now is getting an automatic, (TH400). I used a powerglide column, rebuilt it and got the parts from shiftworks to convert the indicator to a three speed trany, they make one for a 700R4 too. Check it out.

I think a 700r4 will work, but you will have some minor things to overcome. One is, you will need a vacuum over electric switch. Summit has them or you can rob one off of a salvage truck. Second, there is a brake switch that disengages the lock-up or something when you hit the brakes. That too can be had from a salvage yard. Also, the 700r4 has a different type of kickdown cable. hope that helps.
