Isn't this thread about the 6spd re-jiggered 4L80E tci is selling, not a 6L80E like in the gm cars?

i was using it to compare the bowler 4L65E-55097 transmission .... i only asked cause my transmission has not been bought yet but still in the "planning stage" that being said ... i do now know what powerplant torque figures are and i have more options than i thought i would have

But then you said CTS-V and I got all confused!

How did they manage to get the 4 speed 4L80E to be a sixspeed?

A brief discussion here on it: http://www.nastyz28.com/forum/showthread.php?t=171317

It is my understanding that it is a re-enginered L80 trans case. It has 5 forward gears and a lock up converter. If I understood right. I like the tci paddle system because its all internal. no external cylinder or mechanical linkage like all other paddle systems Iv looked into.

This is the 4L80E case, the 6L80E has a much bigger case and many cars will require some tunnel mods to fit it. I believe they used the 4 series case to fit most cars easier. Easier to market that way? With a rating of 850hp it should live behind most 550-600hp street motors for a long time.

I had a 6l90 the beefier version of 6l80 i my 79 c10 i drove it really hard it shift so fast it was really nice transmission it worked fine with 450rwhp.

In the corvette world they seem to handle from 550 to 600 whp anything fine but there was vette's here and there that had problems in that range to.

They don't have any upgrades that solves the issues that people have with them yet.
