What is the fastest geared 4t65e? Can you explain the gearing ratio for my newphew?

The highest gear ratio combo with production 4T65E parts is a 3.69 overall ratio. The stock GTP or supercharged transmissions come with 2.93 aside the CompG 04+ cars which have 3.29s. Most GTs have a 3.29 ratio. The higher the number the faster the car will accelerate as you are multiplying more torque. The downside is slightly loss in mpg and significant traction loss, especially with the 3.69s.
