Keep in mind that you have to have the correct bolt pattern 700-R4. A Chevy trans will not bolt up to a B.O.P. engine. I believe there were some universal 700-R4 trans made. If not, there are companies that make adapter plates for this. You will also need a TH350 cross member.....unless you are dealing with an older A body that has multiple mounting locations for the cross member. One last thing to consider is the lock up torque converter of the 700-R4. There are also companies that offer the controller for this swap.
yes but the 350 turbo like the 400 turbo are vacuum run so you will need to tie into a vacuum line i put a turbo hydromatic 400 in my 1990 silverado that originally had a 700r4 it sucks not having overdrive but it will work also the output shaft is bigger so i needed a compatible transfer case in a 2wd this may not be a problem
The most common type of tranny put behide those were a turbo 350 or turbo 400, you can also put a 700r4 which works with a detent cable, if you wanted to wire up some stuff you can put a 4L60E or a 4L80E which are electronic. A lot of people around my area put a 700R4 since they are not electronic wires, and you also get that extra gear on the highway, since it has overdrive. But the turbo 350, 400 will hold more power if you not going to beef it up. So it realy depends on what you are doing.
no it will not fit at all
Yes
You didn't mention the year of the caprice so I'll try to cover a couple scenarios that will depend on whether it originally had a turbo 350, a metric 200, or a 700R4. First, understand that Turbo 400 Transmissions were made with 2 possible bell housing bolt patterns: One for Chevy engines, the other known as a BOP case which stands for "Buick/Olds/Pontiac and also bolts to older Cadillac engines. A turbo 400 is also longer and has a larger diameter drive shaft yoke with more splines. So to answer your question, a Chevy turbo 400 case will bolt to a 305 Chevy engine (a BOP case won't), but to use a turbo 400 transmission in a car that has a 305 engine and most likely had a turbo 350 or 700R4 transmission originally you would have to change or relocate the crossmember, change the driveshaft yoke and have the driveshaft shortened. The shift linkage is in the same location -- the only difference being if it had a 700R4 the shift indicator would read L2 for low gear and OD for Drive if you put a 3 speed non overdrive transmission in place of a 700R4. The vacuum modulator is on the passenger side front of a 400 instead of the back for a turbo 350 so you'd have to run a new vacuum line, or in the case of a metric 200 or 700R4 which has no vacuum modulator you'd have to run a vacuum line. Also, if it originally had a metric 200 or 700R4 with a lockup torque converter you'll lose that with a turbo 400 and the check engine light will stay on as turbo 400's don't have lockup torque converters -- at least I've never seen one and don't believe they ever made a lockup 400, if they did it's rare. Turbo 400's also use an electronic downshift solenoid with a switch mounted to either the throttle linkage or under the dash near the gas pedal (to downshift for passing gear). Technically a swap like this is possible, but it's much easier (and probably cheaper) to replace the transmission with the same kind you removed, or rebuild the one you have.
It can be done.
You can if it has the Chevy bolt pattern.
i would put a 700r4 that's a good one for the gas per mile and towing or 350 turbo for the other
A turbo 400 is an automatic transmission, so yes, it will shift itself, unless someone has put in a manual valve body or transmission brake -- both of which are mainly used by racers.
As long as it has the Chevy bolt pattern, yes.
NO. If it is a 1/2 ton then it MUST have the 4L60E put back in it. The 3/4 tons MUST have the 4L80E put in them.
That 99 tahoe MUST have the 4L60E transmission put in it.
