I personally like standard transmissions for the way I drive. I like doing something when I drive. The thought of just sticking my foot on the accelerator makes me think of a Cadillac 
. I've seen a lot of vettes that get great times at the track ( Bandimere speedway ) with automatics. Choose what you like.
The std cars have a beefier rear end (D44) and better gearing.
I would look for what you want the most. Don't settle because there are a lot of C4's out there.
Good luck and have fun

Calderone? I thought Crockett put you away...
The autos are different, but they are a case of "you have to drive it." Test drive some of both and make your decision based on that.
If you want a stick, stray away from the 4+3 Manual box used from 1984 to 1988, get the ZF6 6-Speed used from 1989 - 1996. On the 4+3, the OD unit can have issues. Autos, not so much an issue of the year, just get a maintained car.

nothing shifts faster than a machine. Now granted you have to build the machine right.. But if you look at all the top street car guys, they are leaving off of trans brakes and automatics... The torque converter absorbs alot of the driveline stress manual cars see.. again, you have to have the right converter (see sig).
Although I enjoy rowing my own gears.. having to drive in stop and go rush hour traffic with a clutch sucks! Evaluate what you will be using it for the most and go from there!

Hi guys ! thanx for your reply
Im just new to the Vette world
and i ve been drivin a 1982 Firebird S/E since 1996
i think a Corvette is the next step from Thirdgens (which i love)
but i need a real performance street car (not modified) and i think that's the Vette,my bird is automatic and the automatic trannys
steal away the action i think,shifting up and down on a manual transmission is fun ! There are more AT c4's than std transmission ones ??? Im from Chile so,here there are not much Vettes or Thirdgens ...here is a lot of New japanese cars
thanx !

The A4 also has about 8% greater horsepower deficit to the rear wheels than the M6.
If you do go with the A4, the automatics outnumber the manuals about 5 to 1, make sure you get the performance axle. The gear ratio on the G92 is 3.07, as opposed to 2.59 on the base gear.

I think the 700R4 and 4+3 are about equal in terms of hp loss, and the ZF6 is better than both.
Drive all 3.
The auto vette is boooooring to drive. The manuals also have the stronger Dana 44 rear. This was an option on autos.

Not true at all. My automatic is not boring to drive. And the dana 44 was never offered as a option on a automatic vette.

I have had the 3:07 in both the L98 and LT1's, it makes a BIG difference over the stock gears. What makes the six speeds seem so much faster is the rear end ratio's, usually 3:4x. Drive a 4+3 with 3:07's (most of them came with them) and an at with 3:07's, and you won't notice that much difference. Unless you drive all out, I believe the at actually feels faster. JMO

The AT always felt faster to me leaving a stop light (probably was) , Stab it and go. 6 spds can be a bit more fun....Unless you are in traffic a lot. They both have pros and cons go drive both and see what works for you. Dont worry about what everyone else says, youre the one that has to live with it.
