Howdy, new here and this is my 1st topic, so my apologies if this is the wrong board to post this type of question on.
Anyways, I recently purchased a 1968 Pontiac LeMans, 400 ci V8 in it, and a THM400 automatic transmission, or so I'm lead to believe. The car drives, but the transmission slips in what I believe is '3', and while in '2', it doesn't slip, but it doesn't have any pull to it and takes a long time to accelerate to approximately 50mph, where it then ceases to increase acceleration.
I wish I knew how to explain that a bit better, or actually knew what I was talking about, but that's the best I can do with my limited knowledge on the matter, haha. Currently a 21 year-old AST student.
I'm faced with 2 options, I think.
Keep the automatic transmission, and get a rebuild kit. Or get a manual transmission conversion kit.
I've always been a fan of manual cars, automatic makes me feel bored. Also I don't intend to race or take this car to the track or anything, so I'm not awfully concerned about performance or lap times, etc.
I'm leaning towards the manual conversion, however I know next to nothing, nor do I have experience with doing any of the work involved with either option. So my question is, what all do I need to get in order to successfully do this conversion?
I see that there are kits available, such as this Keisler ClassicFit? RS® and TKO Kits | 1968-1972 | Chevelle - GTO | GM | Keisler Engineering, Inc | Keisler Engineering - KeislerAuto.com
, but I'm not sure if that covers everything that I'll need. Or if that link is even showing the right things I need for my transmission altogether, rofl.
I asked a teacher what all I'd need to purchase to do something like this, and he listed:
The transmission itself
Flywheel - Pontiac 400 ci specific
Bellhousing - Pontiac 400 ci specific
Clutch Petal w/ related linkage
He said that most of those components do not need to be/ don't come Pontiac 400 ci V8 specific and can be/are generic.
If anyone can verify that, and could point me in the right direction I'd be truely greatfull. I'm actually trying to learn the whats, hows and whys of this and will be doing all the labor myself with the help of other students, so I really need to understand whats going on so I don't &%^* anything up.
Sorry for the lengthy post, figured it was worth being thorough so people can give me accurate information and don't have to ask me questions later on. Hopefully I've listed everything correctly and given the right parts I have, haha.
Thanks for any and all help regarding this.
