I just rebuilt my tranny and it ran just fine for about 1000 miles. Then it happened again, no 3rd or 4th gear. Originally the 3-4 clutch friction plates were worn out. Now I don't know what the problem is. I took it apart again and the friction plates are good. Any help sure would be appreciated. The tranny is in a 2001 GMC Yukon XL 4X4 with a 5.3L engine Thank you in advance.
