Yes Randy. I'm still running what i believe to be the original factory T'Ultra that has never been rebilt. It works just fine. AND it has well over 50K miles on it.

But there is the gas mileage issue for me that an overdrive trans would greatly improve. I drive at least 2k miles per year mostly interstate hiway.

I do NOT recommend replaceing any GOOD T'ultra as long as it is running just fine. But the person who started this thread apparently does not have a good T'Ultra and needs to take some kind of action?????

When my T'Ultra goes bad i'm not real sure what i will do. Prefer an overdrive trans but cost will be the deciding factor.


Many of the younger set like a lot of low speed torque and fast take offs from traffic lites. That is hard on any transmission. But the more modern transmissions will take hot rodding alot better than anyof the 50's or 60's automatic transmisssions.

If it wasn't for the overdrive of the modern transmissions i doubt that i would be encouraged to use them and would just continue with the T'Ultra and research rebuild parts for it.

I do very little low speed hot rodding, nearly none. So little in fact that i rarely use "D". Always use "H". Most all of my driveing is interstate hiway at 70-80 mph. So it's the overdrive and LONGEVITY that the modern OD transmissions offer..
