I went with the new valve body and shift kit from CKPerformance.com at the advice of many people...Also went with the 3200 PTC race converter, non lock up, with the converter conversion valve....Had it all installed this past week and picked it up today...Man what a difference, well worth the money!!! I highly reccomend CKPerformance.Com for shift kits and PTC for converters , ptcrace.com for converters!!! I can't wait to get her to the track for some numbers after the improvements 8)
