GM Chevy Ford T5 5 Speed Non World Class Transmission Rebuild Kit 1983-1994 This is a GM or Ford T5 Non-World Class 81-On 5-speed Transmission Rebuild Kit The T5 Transmission will be cast 13-52. Please idenitfy what you have! The Non-World Class transmissions have all brass synchro rings. That is what we are selling here! World Class transmissions have fiber lined rings for all the synchro rings except 5th. No synchro rings are included with this rebuild kit but you need to know if it is World Class or Non-World because they use different bearings. This fits various Ford cars usually 83-84. On GM cars they are usually in a 81-86 Camaro or Firebird. In GM trucks this would usually be the 83-93 S10. This kit comes with all the main roller bearings, seals and a small parts kit. (Small parts kit includes: snap rings, thrust washers, needle bearings, etc.) There are no springs and keys in this kit! I do sell them if you think you need them, let me know. I will add them in the kit for just the cost of the springs and keys if purchased and sent along with the kit.
