66 valve body question

[my66coupe]

My tranny has not been shifting from 1st to 2nd when I use my B&M megashifter, I adjusted the cable, checked vacumm lines, and finally decided to tair down my valve body. A few months back, I installed a transgo shift kit, I was told that I may have lost the check ball that goes on top of the valve body, Does the 66 have a ball that goes on top? If so, i definetly am not seeing one. thanks

Also, anyone know the inch pounds everything is supposed to be secured at?

well I took my valve body to my work and the 3 mechanics there said they were sure that it had at least 6 check balls. They sent me to a Lee Myles tranny place, the guy there said that the "green dot" c-4 doesnt have check balls, and that the shift kit im using would still function as a regular green dot just makes the shifts harder. Soo basically I spent 180 on a B&M megashifter and I cant shift the gears manually. The guy at Lee Myles said I can get a 67-68 valve body if I want to shift manually or leave it in drive for auto. Any thoughts here? My original problem for all of you that dont know, is when I go into 1st then into second, the tranny still stays in first and doesnt shift into 2nd. but when I put it into Drive or the 3 on the megashifter, it will finally shift into 2nd and then 3rd... Maybe my cable is way off, Park, Reverse, Nuetral and Drive seem fine, but i dunno.

Yea... you have a check ball in the upper valve body... It wouldn't be the cause of your 1-2 shift problem though. Are you sure you drilled the right place when you did the shift kit?

 

[my66coupe]

Im positive I drilled the right hole, and the guy at Lee Myles was 100% positive about there being no check ball. Any other thoughts?

I was looking at my 1966 Motor's Manual when I responded... You might check for too much torque on the valve body. That could possibly keep the manual valve closed or hung up (use 10-12 inch pounds), but thats a longshot. Consider ordering a new valvebody from TCI, or another vendor, that will give you all the shift options you may want. The stock valvebody on pre-67 C4s are junk to begin with.

Ok, this valve body from TCI states that it is for 1970 and later, will it fit my 1966 C-4?

Keep looking... thats not the one you want for the 66. You can get the whole C4 racing tranny for $750... you'll need a new torque converter, but you'd probably want that anyway. Pretty good tranny for the money..

Yea Im 16 and have about 100 dollars to my name at this point, soo that is entirely out of the question, where else can I find a 1967 and up valve body, ebay has like 2 right now, anywhere else though?

Check around transmission shops... they can even just fix up the one you have now. A hundred bucks would be more than enough, or offer to sweep floors for a few days..
