65E max RPM
What's the maximum RPM that the 4t65E is capable of in stock form? Reason I ask is because the redline on my engine is nearly 7,000 RPM but it shifts at 6,400 RPM everytime, and the redline on the tach is set for 6,500 RPM as well. I'm thinking that the 65E isn't "supposed" to shift over 6,400 RPM maybe? Torque management is insane though.. It cuts back power severely just before, during, and a second after it shifts. It's annoying.

It's not really a max RPM...
I'd highly doubt you'd ever get that engine to spin up to the point of cavitating that trans pump. |

Those 65s are much better at high rpm shifting than the 60s. They have more vanes in the pump. I've read about people reving them up to 7k in turbo cars before.

I also notice some of the torque management quirks he was talking about, I just never really knew what to attribute them too...so im guessing a high performance PCM would really wake these cars up eh? |
I think a chip with 6500rpm shift points would help wake up that engine quite well.

Sounds like the motor is held back... Shame on GM __________________ Best Car Insurance | Auto Protection Today | FREE Trade-In Quote |
