Interview with Tommy Davis of Prestige Automotive

Me- Do you think my Tahoe could benefit from changing the gear ratio from 3:73 to 4:30?

Tommy-You would have much better acceleration and could hold a gear towing large loads but it will be expensive to regear.

me-Do you think it would be worth the money to do it?

Tommy- I would rather build up your torque converter or completely replace it with a different model, This would save you much more money and give you the same results as changing the gear ratio but your gas mileage would be a little bit better.

Me- have you ever done this before in place of a gear swap?

Tommy- There have been multiple occasions where i have done torque converter work on these late model GM trucks and cars because from the factory GM is not putting in a torque converter that is proficient.

This is not the response i expected to get at all, I thought in full that he would tell me to go on and re-gear. Right now i am running a 3:73 gear ratio which would be just about right if i was running stock tire size and did not have all the modifications that i do. With all of the extra weight and towing that i do, i thought it would make since to go with a 4:30 gear ratio or possibly 4:56 but Tommy suggested a much better idea. I had never thought about upgrading my torque converter to one that slipped more to generate more torque, imitating what a gear swap would do. I was very happy with the results that i received from my interview. When i was on my way to Interview Tommy  I thought for sure that he would agree with my re-gear idea which he did but he had a much more economical solution to my problem that i would never have known about if i did not interview him. I look forward to following up with Tommy on installing one of these high performance Torque converters in my Tahoe, it would complement my corvette engine swap quite nicely. I trust most any advice that Tommy gives me because he has had experience building race cars since he was my age. He is great at building high performance vehicles and is a mastermind with engine swaps. I drive the only 2007 Tahoe with a 2013 6.2 v8 aluminum block corvette engine in it all thanks to him.
