Default 4L80E

Can a 4L80E be swapped into a 98+ f-body? And what would be involved? I'd really like the strength of a 400, but would miss my overdrive too much...

I'm planning to put one in my Tahoe.It takes a transmission computer,a different flex plate,a converter and a different drive shaft yoke.I think it would fit an f-body with minor dempling of the tunnel.I've been told that they can be built to withstand up to 1200hp and do full throttle shifts into 4th gear.

It'll fit, it's rather expensive to put in though (core is much more expensive than a 400). The nice thing is that your computer can control it.

On a side note, you can get a 400 with overdrive.

You guys ever seen one? They are FREAKING HUGE! They're power sucking monster trannies. Way too much weight, IMO. I have one in my Suburban. FWIW, it's the second one in the 'burb. They're not indestructable. First one lasted about 130k miles.

Hrmm... Looks like I might just be going with a 400. I saw one the other day, didn't know they were as big as they are.

Yes, I hear that they will suck up a lot of power compared to the 4L60.
