700R4 ISSUES!!
Here it is in a nut shell. I just had my 700R4 rebuilt, and it turns out the car had a trans swap somewhere down the line and recieved a 6 cyl trans in the original 90's place. Here is my problem. After the right valve body and misc parts were replace with v8 parts. The trans shifts from 1-2 great but 2-3 and 3-4 you can't even feel the trans shift unless your wide open. It has corvette torque converter, and feels like it has a 4000 stall speed. At 70 on the highway it will kick down in to second grar. I have had many 700's built by this guy and never theese issues. Any help would be much appreciated.
Thanks Mark

Have you talked to the guy who built your transmission for his opinion?
