Stripped bolt in Aux Valve body, HELP!
I was putting my aux valve body in my 93 Corvette 4L60, when the bolt (long one in picture, wouldnt even start. I took it out and the threads were gone. Then I measured the distance up to where it bottomed out and this bolt seems longer than the hole. But, it was there when I took it out as it was the one with the tab to hold the aux body hydraulic tube down.
My question is , can I tap it? Or put a slightly larger bolt in? Thnaks in Advance

I have seen pictures of rebuilds without the tab holding the hydraulic tube in.

If there are a few threads left in the bottom of the hole, then install a stud. The stud should bottom out in the hole and be a little longer (apx. 1/2" longer, trim to length) than the top of the aux. valve body. Tighten the nut here on the clamp that holds the forward accumulator feed tube. Tighten it to 60-75 inch lbs. If there are not enough threads to start with, you will need to helicoil this hole. Take it to a machine shop and have this done. Install the correct length bolt here, it usually has yellow paint on top of the bolt and is a little shorter than the valve body bolts. Tighten it to 80-95 inch lbs.

Also, is this bolt the correct length anyways? I am wondering if the shop here that originally did it put the right one in?
The FSM has it as a M6x1x45

"Is the purpose of this bolt just to hold the forward accumulator tube?"
No, it is to hold the housing to the case. Some 700R4's do not have the clamp to hold the forward accumulator tube here, but in another place. The bolt that is supposed to be here measures 1.85" in length below the head of the bolt. I have had a few cores come in over the years that had the wrong bolt and/or the hole was stripped.

Drill out the hole and put in a zerk or helicoil. Torque to 90inlb.
