Manual to Auto, Can it be done???

[keza87]

Don't flame me for doing this, but it was an agreement before buying the car!

Me and a mate have gone halfs in a manual VN commodore (89 S1) and I have agreed that he can have the manual box and associated parts and I will get his auto and associated parts.

Now, from what I have read the crack is a slightly different length between the series 1 auto and manuals and I know he needs to get a different manual flywheel. But Will the auto box fit behind the manual motor with the auto drive plate and stuff?? without it being too hard to do

Thanks in advance

anything is possible, as your already aware the s1 manual has a 6bolt flywheel, not sure on the s1 auto setup, however s2 is all 8bolt. the rest will bolt up as is. why not just swap cars with your mate or do a complete engine/trans swap to make it easier

NO, the auto flexplate will not bolt up to a manual engine. The only way to convert from manual to auto is buy an auto engine.

The problem is that the wreck we bought will not be roadworthy again due to rust and a few other things. Plus we don't even know how many KM is on this car and the motor doesn't look the best but still runs once its warmed up.

I suppose another way would be to change the cranks over, and again we don't know the condition of that either.

i would be that mate:P yeah dam about that rust! was it under the boot carpet? the manual box is getting in my car one way or the other!!!

yeah man can be done quite easily if both engines are removed from the cars. Depending on how hard you rekon that is, the engine removal would be the hardest part...
Taking the motor out is easy...pull everything connecting the car to the motor off. Its finding where it all goes back on that is the hard part. Photos are really helpful.
Just do a complete engine n transmission swap with your mate. Cause im not sure of the 6 and 8 bolts cranks. I do know however that getting the torque converter off an auto is a bitch when its still in the car because the only way to get to the bolts on the TC is to undo the plate under it, n there is f'all room the get the bolts off.

VPioneer, i think you need to read the 1st post again.......

He wants to know if the auto will bolt to a manual engine, which it wont! He knows he can swap the engine & transmission but he doesnt want to do that. Although, it may be his only hope.

[mischa]

well the engine is not going to swap, so the auto-manual will happen, but not auto-manual. but would u be able to do it if we swaped the cranks?

[Blown V6 Hatch]

You could change the cranks, but its a lot of work when another auto engine is only worth $250 odd from the wreckers. Its also a real gamble changing a crank from one engine to another without measuring the rod journals, main journals and rod ends to make sure its all good!

[keza87]

Yeh, I wouldn't be buying another engine for a car that can't even be registered again. Maybe just go to pick and payless and take a crank out of an auto there. All I want is the car to be movable without having to tow or push the thing

He wants to know if the auto will bolt to a manual engine, which it wont!

is this the same for a VP bcos i asked the same question on here not too long ago.
i was going to buy a manual car to use the motor in my auto VP and ppl were trying to tell me it would be a simple swap as long is you bring over the flywheel...

well today i finally bought a 91VN so i can put the motor into my 93VP (both autos as i didnt believe the manual-auto would be a straight swap)...and seeing as you sound like quite a knowledgable person, blown V6 hatch, do you know if this would not work at all?

okay
I'm MASSIVELY confused as to which motor is going to which car or whatever

but basically:

1. a VN series 1 motor has a different crank for auto and manual.
- You cannot convert a manual VN series 1 MANUAL motor to an AUTO (easily)
- You CAN get a flywheel from CRS that will suit a MANUAL box on an AUTO Series 1 motor.

2. a VN series 2 motor (and vp, and vr motor) are the same crank for both manual and auto. - as far as i know, this crank is DIFFERENT to the vn series 1 crank - and is not interchangable.
- VN series 2 manual gearbox and flywheel can bolt onto a vn series 2 auto motor no problem, and vise versa.

As far as i know, the actual t5 gearbox is the same throughout the range... though the bellhousing did change at some stage, not sure when. (I'm GUESSING s1/s2 change)
