Default TH400 or 4L80E

I have a perfectly functioning TH400, car runs great with it. But the winter has got me thinking. I'm about to buy a 4L80E that lost reverse for $100. I took apart the TH400 and had an engineer buddy help me set all the tolerances and I assembled it so I'm not intimidated by taking it apart, I'm just indecisive.

I believe I could sell my whole TH400 setup (converter, pan, dip stick) for $1100-$1500. I got an 80E for $100. Converter for that would be $600-$900. Mod the crossmember, driveshaft, figure out how to make it a FMVB.

Anyone done the swap? And liked it? Hate it? How much weight did you add?

Do the 80. You can run a lower gear, and still cruise the highway with OD.

I'm gonna keep the same rear gear. I won't be buying a wot lockup converter. I mainly just want better than 13mpg cruising and to be able I drive it further than bowling green and back with 22gallons of E85. Lol

Don't forget about a shift controller unless you plan to manually shift the 80.

I still say 4L80 and never look back. Was the best thing I did to my car - right up until the point I swapped the 80 out for a 6 speed!

Just get a manual controller for the 80e from Jakes.

A buddy of mine has a 69 chevelle with a 724hp 507 big block and he switched from a 400 to an 80e with a Jakes manual controller and he said its the best thing he could have done, he loves it.

Did the swap wired FMVB. Ratcheting it gets old after a while, but the trans was a beast after it was set-up. I used the transgo HD2, a edge 9 1/2" 3800 stall with a toggled lock-up.

I wonder what coulda caused reverse to go out? Could it be just a band? Or a solenoid?

I made a thread in the trans section about how to make it a FMVB. Jake posted and said he would give me a few tips (pretty freaking cool) so we'll see! I'm gonna buy it as soon as I get back in town. Can't wait to pull it apart!

im rebuilding a 80 right now , no reverse , the direct clutches where toast ....... everyone says the bands breaks , but the direct clutch in mine there is no fiber anymore all steels .


this is my 1st 80 build also and if you done a 400 there pretty easy , i bought the tools for the overdrive clutch assembly , have yet to put that part together , but everything else is normal stuff for a auto .


if i was you i would buy it .

I'd get with Chris at Circle D, spend a couple more bucks and get a BADASS lockup converter. Make use of a key feature for $200 more than the proposed $900... In the long run you'll never notice that $200 is missing from your wallet and it's there if you want to lock her up and see how it goes...

i was thinking about their $850 it $900 one. I can assure you I'll never want to lock it WOT, so I would save the $200. I'm also considering a revmax or yank. I know people with all three of those and all have great results.
