The only problem with you switching to an overdrive would be durability loss. The th400 is much stronger than any stock 200 700 or 4l60. I would personally go with gear vendors if it is in your price range. And if you had to get an overdrive a 4l80 would be the better of the 4 overdrive trannies.
4L60E swap behind BBC?
Hi Folks-
Well, my new car isn't here yet, but I'm already thinking of mods! It's a 70 Malibu with a 427/TH400/12 bolt with 3.73 combo. I am planning on cruising the car down to the beach, which is about 2 hours away, which is making me consider an OD tranny. I do believe I got a little bit spoiled by my Grand Nationals and their driveability! What trans would be the best choice for this application? 4L60E? 4L80E? Vendors? Thanks!
