4+3 trans questions?
Since the search for the site keeps giving me an error.
I need to know 4+3 transmission; did these come in the 86's?
Are these auto or manual?
Is 4+3 a different name for the 700r4?
I am getting difference of knowledge from some local guys about an 86 I am getting this weekend.
Thanks
Ray

1. Yes 84-88
2. Both! It is a Borg Warner Super T-10 4-speed manual with an automatic 2-speed overdrive mated to the tail shaft. The car has a clutch and everything, you drive it just like any other stick car and the overdrive can be operated by a little button on the top of the shifter or the computer can control it.
3. Yes, a 700R4 is a 4-speed automatic.
Here are 2 of mine, dirty one had just come out of the car.

4+3 is the manual trans that came in the Vette 84-88. It is a 2 speed auto OD gear box, bolted to a T10 manual gear box.
4 gear ratios in the T10. W/ 3 of these gears, the OD is avaiable.
Most of the problems were worked out in the later 86 versions. Before that, expect problems. All can be fixed w/ a rebuild. OD unit was the problem.

So the guy I am getting the car from says it is a 4+3 Automatic. It is actually a 700r4 this is a late year production with the aluminum heads.
Thanks

Ok, look inside the car. If you see a clutch pedal it is a 4+3 and you'll see the shifter has the shift pattern on it (which doubles as the overdrive button). If there is only a gas and one large brake pedal it is a 700R4 automatic.
Pop the hood and look at the valve covers. If the valve covers have 4 bolts in a line down the center of them then they are an aluminum heads.
This is my '87, but the engine will look the same. These valve covers bolts mean aluminum heads. If it were 4 bolts on the outter edges of the covers it is an iron head.
