Switching from a 60E to new 6 speed auto I'm toying with this idea. Whats the pros and cons beside costs. I can sell my 60E for some good cash. I'm wanting to stay with the 4.11's , but want more top end. Would this switch help. On motor the 4.11's are ideal, not so on the jug. Would the 6 speed just act like a close ratio manual and would I still run out of gear? My son thinks that we would just be in each gear for a shorter time and thus shifting 5 times instead of 3 or sometimes 4. The 6 speed should keep us in the power band better then the big spread of the 60 e.
It 's this or a new carrier and gear set, maybe a spool.

That is assuming you already running a Gen IV motor.
If used for racing you could have 20 gears but the final gear in racing should be a 1-1 ratio. You don't need a OD gear for racing. If you are on the limiter thru the traps then you may need a taller tire or a higher gear.

Here's a question. How do so many people run 3.73's with their 4L60e? I'm only running to 6300-6400 with stock height tire and I am just hitting the limiter in 3rd and my best trap to date is only 110 in 3000 DA. I'll be in the low 120's with spray and I'll be well into OD at that point. Is shifting to 4th going to hurt me a lot or will I be ok?

I miss my stock 3.42's for N20 passes.

I understand that you should cross the traps in your 1-1 gear, be it 2nd , 3rd 4th or even 5th. What I'm looking at is with 4 gears before the 1-1 how much further down the track will I be. With a higher 1st gear it will be easier to launch, allow the car to stay in the power band on the 1-2 shift etc.
We would also like to go back to the TX mile. The set up now runs out of gear to soon.
The 80E does look like the best option. The TCI 6x is based off it.

i think the TCI 6 sp is a 4L80E modded-not sure if it changes 4th or not-it also has to be paddle shifted i think-i was curious if it would stay in the selected gear
i know on my new truck with the GM 6 sp, in manuel mod you can shift it man., but its not a full man like your used to (if you got loose and peddaled it, it would change gears downard and back up to the highest gear selected)

Yes it is based off of the 80E. They have an out law shifter that has buttons for the OD, it looks like a nice piece. The trans is fully programable with a stand alone controller. Its just $$$$.
yea, i just saw that shifter today-i wanted to keep my col shift, and use some kind of steering wheel mounted paddle(4l80e), and saw this-if i went to a floor shift, i would just use the B & M pro rachet and switch it to 4 sp-but the TCI one would work for their 6 sp, as theres no shifter with 6 speed detent(yet, lol)

If you have traction, you'll LOVE first gear of a 6L80/90 with 4.1 gears. I have AWD with my TBSS and I love launching with it. Both transmissions have essentially the same final O/D ratio and with 4.1 gears...the only way to bring RPM's down at the top end is by playing with tire diameter. If you can afford the swap and have a good tuner, you can't beat a 6L80/90.
