4L60E, 4L80E, or 4L65E

I paid 750-850US for my 4l80e with 20k on it. Stock form it'll be fine taking 800 flywheel ponies.



Its all in where you shop really. My friend just picked up a 11k 4l60e that was rebuilt with a shift kit for 950US

The 4L80E will fit the 67-69 Camaros without floor mods, but the cooling line area is very tight. I found one from BTE from Steve at Oldani Motorsports for $1865. There is no core charge and it will hold 850-900 HP. That does not include a converter and you'll also need a controller to control the trans.

Guys first post. I have been running a 700r4 in a 67 chevy ll for a couple of years with a mild 383 and nitrous. They just won't last with any power over 500 or so.

I am switching power adders to a turbo and going to a 4L80E trans. From what I have read they come from the factory rated at 800ftlb.. I like the odds of it lasting. I have an empty case test fitting. I just got my engine back so in a month or so I should have it in. I will be using a TCI controller.... which is a F.A.S.T. system like the fuel injection.

There are a couple ways to control it. One with a stand alone aftermarket controller. The other is to make it a manual valvebody. I also think that you can get a certain yr. camaro ecu to control it also..... but I am not positive.

The converters are more expensive which is a downer but so is rebuilding 700r4's or 4L60E's.

Welcome to the forum Lethal. Did the 4L80 fit in your 67 Chevy II without floorpan mods? I have the TCI controller on my 4L60. Once you've had a computer controlled automatic you will never go back to a "dumb" transmission.

I have a empty case I am using now. I just got my engine back from the builder and will put the case on and know for sure. I will do some work on the tunnel. I just have not decided if I will cut the tunnel out and make a new one or just try to modify some areas.

The tunnel in the chevyll is small around the tail housing and will surely get work. I will curt off the extra leg of the trans and work on the "rib" on top if I just modify my tunnel instead of replace.

I am using the F.A.S.T. controller for my injection so I was happy to see the tci unit.

I'm using the Big Stuff 3 EFI for mine and it has a built-in trans controller, which eliminates one extra box. Can't wait to try it.

Myclone...Excellent post! I think I'll just stick with my old TH400!
