Yes your auto is a 700r4 and if you get a v8 your gonna need a new bellhousing

700R4 is a fixed-bell transmission, so he'll need to replace it.

ex-x-fire

He can swap over the tailshaft housing if he gets a non f-body th700r4.

allright guys im kinda new to this now is the 700r4 tranny one of the better trannys can u slap shift them? guy from school said u can not sure

now all i will need is a new bell housing to fit with the v8

and woudlnt it be if i had a 700r4 wouldnt it be possi mine dont seem to spin possi but maybe the v6 dont have the power either thanks

The 700R4 can be manually shifted.

As I already stated the 700R4 is a fixed-bell transmission so you do not need "a new bellhousing" you need a new transmission.

The choice of transmission did not affect whether or not the car got an LSD. I have had 700R4 cars with and without that option. A V6 would almost certainly have an open 3.42 10-bolt.

allright so there is no sence of doing the swap with out getting a new tranny...so sounds like a pretty good job to do this swap

also do u know the top speed of the v6 auto or close to what it should be

and so maual shift u mean by like putting down in 1 top that gear out push it up into 2 and keep going?

Wrong... 90-92 3.1 cars got the 3.23 with the 700R4 (renamed the 4L60 in 1992), but it's still going to give the one-tire fire.

And the transmission is the least of your worries... Front springs, engine mounts, engine wiring harness also need to be replaced or reworked.

the 4L60 started in 1993...in the 4th gens

Top speed isn't gonna be much, due to the stock v6 being pretty low on power, and the stock 700r4 being incapable of 4th gear at WOT(not sure if this applies to the v8 transmissions or not). I reckon 120 mph at most. You won't break 150 or so without nitrous, boost, or aluminum heads.
Even at 6k rpm, 3rd gear will only get you up to 135 mph, with a 3.42 rear, and stock springs won't hold up past that, if they even do at that. Plus the stock engine doesn't flow much past 5500 if memory serves. But I've never actually driven a stock one, and don't have a working tach yet on my car.

Technically the 4l60 is only designated for the V8's, the V6's still had the 700R4 in 1993. Yes they are virtually identical but it depends on who you talk to.


My 700R4 came out of a '93 V6 Firebird. It was missing a few check ***** that the earlier 700R4's had but identical other than that. With the probuilt auto shift kit it will hold any gear and 3-4 shift if you want it too...

Started in 1992 with the Federal mandate that all transmissions be named based on number of speeds, engine mounting, and power capability... The electronic controls were added in 1993, which made the 700R4/4L60 into the 4L60E...

allright guys well i get differant opinions everyday somepeople say it will line up other say it needs a differant bell housing and others say it just wont work

firebird904

A 700r4 built to work with a 2.8/3.1 will not work with a v8. You can use the transmission out of a 4.3 v6 because they do have the same bell housing as a v8.

Actually, the 1991 service manual lists the transmission as a 4L60.

Top speed for any EFI thirdgen that came without V or Z rated tires is 115mph. That's when the speed limiter kicks in. Don't believe anyone that says otherwise, because it just ain't so.

u really need to look at the proms for the 2.8 cars they are not speed limited, only the 3.1 and v8 cars are

Pillsbry10

iTrader: (1)

oh snap

what now drew

Drew

iTrader: (58)

I guess I'll have to check the same way I have on L03s and LH0s... The trouble is, I don't intend to buy a LB8 any time soon. It's funny that the only combo with a speedometer I haven't tried to bury is the one that supposedly doesn't have a limiter. Odd that GM would make an exception... Oh well, carry on. LOL

Pillsbry10

iTrader: (1)

thats becuase they didnt think that car could ever get up to that speed...and without boost im not sure it can lol

Project 3.4 Camaro

^, though it wouldn't take boost, N/A could do it too no doubt, also trans won't go into 4th gear at WOT, which is in and of itself a form of limiter, Idk if the v8 autos do this or not.

they cant unless they have about 5 miles and a slight downhill run ont he road.

my 89 toped out at 117 on a perfectly flat road bone stock.lil while later i got it to 126/7 on the nj parkway going down a grade.

with the stock ecm running my first turbo motor i could easily go 130.

the 2.8 proms do have a govener but they are all set to 255

ur typical person will never get a 2.8 over 110 it takes way to long at wot and u need alot of room

Drew

Without the B4C valve they won't shift into OD at more then about 1/2 throttle... It happens around 130-140mph. It's really annoying when it downshifts at 130mph, rpm goes up but the car feels like it slows down.

The 3.1L took a lot of road to get up to 115mph. Enough I was always worried about passing a trooper.

to get out of a ticket in a v6 all you have to do is pop the hood and deny that the car goes that fast. they will fall for it.

Drew

iTrader: (58)

Pop the hood before or after the Rodney King style beat down? lol

Pillsbry10

iTrader: (1)
