4l60-e questions

[sleepa]

Kind of have an auto gearbox issue in my LS1 VX. I know it's the 4l60-e, but just wondering if all the auto's from VR were the same, coz if I can get one from a VS or VT then that would be a bit cheaper and easier for me.

Also are the V8 gearboxes different from the V6's? And will a 5L V8 auto fit behind the 5.7?

Cheers

The aut behind your ls1 is a 4l65e which is basicly a beefed up version of the 4l60e.
and no a vr auto is th700. Not the same

the th700 and the 4l60-e are the same box, its just they used to be called the th700 but changed the name, from what ive read the 4l60-e started from vr and they still use it in the ve

to the op, you need to get a 4l65e as said above

hmmm, I thought it had the 4l60-e, I didn't think they brought the 4l65 in till a few years after. But a 4l65-e would be better anyway if I can get one.

yeh sorry buddy you would be right, this write up is from another forum. i wonder if you can bolt a 4l65-e straight up to an ls1?

VX came out with a 4L60E. You will need a V8 version and preferably from a VT series 2 (5L and 5.7L have a different bell housing bolt pattern).

Also a T700 and a 4L60E are not directly interchangable so don't even bother wasting your time on that one lol

So you can't fit a 5L gearbox to a 5.7L. Are the V6's actually weaker or have different specs or gear ratios, or will the bolt holes just not line up?
Will a 4l65-e bolt straight up to the VX LS1, and if so what exactly did they come in and where do I get one?

V6 4L60E has different input shaft and different bell-housing.

Thanks guys, so my only choice is a 4L60-e from a 5.7L V8, or (perhaps) a 4L65-e, Anyone know if they bolt straight up in a VX?

An auto from the vt ls1 will fit into vx vy etc and vise versa.

4L65E needs its own trans settings to be grafted into the tune. It's set up for different base pressures and apply times.

If your car is tuned or is going to be as soon as the 4L65E goes in it shouldn't be an issue as long as the tuner has the software.

4L60E or a T56 would be my tip

Cheers, what would be involved in putting a manual in the vx?
Is it just a matter of swapping over the torque converter for a clutch, manual box, shifter, and pedal assembly? Or would I need to change the computer over or get it tuned for the manual?
I suspect only the LS1 versions would fit again.

And finally I have never driven a manual commodore, so what is the gearbox like? Is it smooth? notchy? firm shifts? Can you cruise around easily? Is the clutch soft as butter or over the top stiff?

I had a manual 180sx previously, fun to drive, but the gearbox needed warming up for a good 10 mins otherwise it would be notchy, and would be hard to engage first. On full throttle runs it wouldn't go into gear sometimes. And the clutch was a major bitch in traffic. Just want to know if these type of issues are common coz I want a car that is easy to drive, but can go hard when needed.
