Hi Guys,
I'm looking at buying a vortec motor and 4l60e system complete from a 98 Suburban, and it comes with the transfer case as well.

I was wondering if I can put the 4l60e from this straight into the car, or will it require changing the input shaft, crossmember alteration, or even drifeshaft modificatio, or is it simply not possible?

The 4L60E is electronically shifted. 3rd Gens don't have the electrical hook ups to make shifts happen.

There are aftermarket controllers that can be added to vehicles that don't have electronic shift controls. But this is a far cry from a drop in swap.

And the output shaft and tailhousing need swapped to parts for 2wd.

evilstuie

Yeah sorry, I forgot to mention it will go in the same time I switch the motor to OBDII with a 4 tooth reluctor etc

The output shaft replacement, would that require taking the whole transmission apart? or just unbolt the back end?

New question...

1995 Corvette 4l60E
Will that bolt up direct with obd2 setup?
Will I need a different cross-member and output shaft/housing?

Formula 305

The Corvette trans is not OBD2 so the shift controller may differ, and the corvette trans will not have provisions for a torque arm mount. You'd save yourself a lot of headaches if you just bought a F-body trans

evilstuie

So a 0411 PCM won't be able to control the 4L60E?

Unfortunately I'm in Australia, and f-bodys are extremely rare as is without thinking about parts.

Is the torque arm mandatory, or can I get away without it?

evilstuie

The transmission is a 614BWDY13087683 Toledo 08681348 if that helps?

Yes , the torque arm is mandatory , unless your planning on re engineering the entire rear suspension .

However , what is NOT mandatory is for it to be attached to the transmission's tailshaft housing . There are kits available to re locate torque arm mount from the transmission to the transmission's crossmember , thus negating the need for a 'third gen specific" transmission , at least as far as the torque arm goes . These kits are usually used by racing folks who put the "turbo 350" 3 speed automatic into third gens , as the Turbo 350 or 400 don't have the special mount cast into their tailshaft housings .

So , if it bolts to the engine , is good driveshaft wise , and the only mechanical difference is the torque arm mount , that CAN be worked around . Now , as far as controlling an electronically shifted transmission in our car , that's where things could get real expen$ive real quick if you gotta end up buying some aftermarket "stand alone" controller to be wired in .....

evilstuie

Thanks for that. I had a look at the aftermarket ones, I've got a mate who's pretty good with a welder so should be able to get him to fabricate the current one to bolt / attach to the crossmember.

The electronic shift will be controlled by the 0411 PCM that's going in along with the vortec bits to run an L31 Express Van tune to allow sequential injection and control the transmission.

The 0411 PCM will control any 95-07ish 4L60E

Avoid 4WD 4L60Es. The corvette unit will work

Dont holdens use 2WD chevy transmissions? The monaro/ute?
I know they use LSx engines, but older ones maybe SBCs with 4L60E's?

If you use the corvette trans, I believe it has the common 4 bolt tailshaft housing and the 700 f body one should bolt right on.

evilstuie

That's good news, so the torque arm mount is on the tailshaft housing?

evilstuie

Hey Pocket,

Yeah they do. SBCs were only used in some 70s cars here, very few and i'm not even sure of the models, but commodores here used 4l60e trannys, its just the corvette one was only $300 so I went for it.

fireburdluvr85

The mount does bolt to the tail shaft housing. You can buy them on eBay for $25-50 all day long but I'm not sure how expensive to get to you.

evilstuie

Awesome. Will a T700r4 tailshaft housing fit a 4l60e?
If so I can just use my old transmission one to fit.

fireburdluvr85

I believe it has to be specific. Has to have the speed sensor housing similar to the ones for the 411 swap. Its been some time since I looked up the pieces. I believe it has to be a 94-95 f body housing. Its still a common 4 bolt housing.

Simple, look at the 4L60E main case. Does the bellhousing come off or is it cast on like the 700R4. If its one piece, then all the externals and most of the internals from your 700R4 will swap over. If its two piece, then you'll have to find a newer trans to pull parts from

The 4L60E changed around 97-99, there wasnt a cutoff year

evilstuie

Yeah the new one is all one piece, no bell housing separation.
