Who has the best trans???

[redevil01]

hey TYF,

so to start this is my 2nd stock replacement 4l60e in a little over a year which sucks and i dont wanna replace it with another crap trans. so my question is who makes the best drop in performance 4l60e im planning on swapping a 6.0 over into it within the year so i dont want one rated to like 400hp and liuke 450tq

Finish Line Transmissions. Performabuilt.

Prepare to drop about $3k

When I was still a mechanic, my shop used to swear by Jasper Engines and Transmissions. We used them for the 10+ years I was there and I think they still use them now.

I build my own with good quality parts and the good sonnax sun shell and bearing. My last trans was built using a monster in a box kit. 400hp is nothing when you build it right. Or spend the money and convert to a 4l80E. Find a good core and you will still have 2k into the trans.

6l80e.
Why bother with inferior parts?

what does it take to put a 6l80e in? Anyone done it yet?

I've heard that it is extremely difficult. Things might have changed since I was into the swaps, but I do remember you needing a standalone computer just to control the transmission. Partly being older trucks have just a BCM, whereas the 6L80 needs a BCM and TCM. Something like that... I want to say the costs were extremely high, around $6-8k.

4L80 is not exactly inferior. The 6 speed was designed to save on gas, not because the 4L80 was poor in performance.

No thank you then! lol.

I've read people swap the 4l80e for the 6l80e apparently the 4l80e holds more hp
