Your welcome Coachreed,
The more I read the more I piece together the story here. As I understand, this 4L60E is the transmission out of a Chev. 4X4, I think? In my day, Chevy and most of GM were, Powerglide, T300, T350, T400, with a mixing of odd ball stuff roto 5's roto 10's Turboglide, and a few Turbo 425's. Never heard of this tranny. Hey you ever think about adapting a stick? Those bugger's you KNOW will work when you install it from the get go..cause you can statically test it on the bench..the principals behind an automatic is it operates off oil pressure created by the front pump and through a series of springs and valves directs that oil pressure throught the valve body. There are sealing rings all over the place, some rubber, some metal and some nylon. These are very suseptable to damage when you dismantle the transmission so I consider it very unwise to not repalce these when you reassemble, use plenty of bearing grease on re-assembly. You might consider a couple assorted sizes of snap ring pliers if you don't have them. Of course, were talking ancient history as I have been out of the loop for so long I may be talking bovine scatology here.
I also gather that there is a lot of similiarity between the vx transmission and the Chev. Is that true?
What about an adapter plate to mate the stock bellhousing and tranny to the back of the Chev block you would need to modify the ring gear/flex plate and an adapter plate to compensate for the extra length. An "ingeniousicle" machinist may help you out in a one of a kind prototype. In my day while the transmissions such as the T 300 and T400 looked similar however the bell housing bolt patterns were different so you couldn't i.e. take a T-400 out of a Cadillac and install it in a Pontiac the bolt patterns were different. The adapter would enable you to do that. Ha Ha ....all this sage advice form a guy from someone who hasn't even looked underneath his own VX...slap my face!!
