I think my gearbox is dying, so..

[StockoVRWagz]

Did bit of a search, with the info I found, I decided it might be easier to rebuild a box while using my old one still, its been like it for ages now and still pretty much works.

Just a few Q's
1/ Which 5.0 Box was the tuffest?
2/ I relise VN's were different to VP? and above so I wont use that
3/ The VT I 5.0L had a different shifter on it? Would that go in my VR, and is that box better than VR/VS (strength and ratios or anything like that)?
4/ Also want to have the bt1 feature of shifting without button pressed. Is this easy to do? I saw somewhere that you just grind out a bit for it to slide freely.
5/ Will also be chucking in my stage 2 kit & corvette servo, is this going to fit on a newer box?

Cheeers.

Dont know too much about auto boxes sorry but I can answer No.1 and 4.
No.1 - VN autos are mechanical cable kick down whereas your VR will be electronic kickdown
No.4 - By this I assume you want to go straight into 2nd without using the button? If so then your method is correct. There is a physical metal stop that the shifter hits on to prevent it going into 2nd and this just needs to be removed with a file. Just remove your plastic shifter surround and inspect the shifter stops (a series of steps in the metal plate). It will become pretty obvious which one has to be removed.
Should'nt you already have this feature being a BT1?

ok, in short, the VN/VP used the 4l60 hydraumatic trans. from VR onwards they used the 4l60e which is a electronically controlled version of the older hydraumatic 4l60 trans. to use the older style VN/VP trans would require you to fit a manual ECU so it doesn't effect the trans. maybe not worth the effort

there are sublte differences with the trans as you go from VR - VS - VT etc and i'm not sure that they are all interchangable. your best bet is to get another trans that has the same numbers on it i.e. 4HDD (1994 model), the 5HDD would represent the trans for the 1995 model etc

all the 4speed 4l60(e) trans have the same ratios.

as for question 3, the shifter isn't attached to the box permanently, just a rod, so if thats in the same place for VR VS VT VX then you will be able to retain your existing shifter assy.

-Yep thats what I thought
-I want to rebuild a new box, while I still use the one in the car now, and yes I have that now and like it.

-Does anyone know what these differences are? I was thinking newer trans would be better If I could get it in. Also, is it even worth getting a 5HDD for it?

-niiice. I much prefer the VT/VX Shifter anyway


Thanks for the help so far

are you going to rebuild the box yourself ?
there's lots of good gear on ebay to go in these , clutch kits, kevlar bands etc.
I need to do the same thing cos my auto's been slipping since trackday dammit.

No.1 - VN autos are mechanical cable kick down whereas your VR will be electronic kickdown


um wrong....

VN- VR use mechanical kick down. ecotec is where the electronic kick down joined the family from memory


vp - vr are basically the same box far as i know.. internally ratios are the same too

Its a 304, still changed when ecotec came in?

[TUF UTE]

vs has electronic kick down. i have a vs 304 aswell. im pretty sure all / most vr's were cable adjusted.

Where does the cable run to? All I can see is the acceleraor cable, and would a loose kickdown cable cause the car to free-rev when its given a slight kick in the guts?

iv got a 94 vr calais 6 v6 and it has electronic kick down. Im sure all vr's are electronic cos when i looked for new one i was told could not use vn or vp trans as vr is electronic

Didnt see this post before..
Yah I want to give it a go myself. Save a few $$ and learn a bit in the process. I might give ebay a look, once I find a box to rebuild.
Cheers

I though this was the case as well.

[CALAIS 6]

also a mate bought a trans from a vn 304 for his vr stato and it didnt fit cos the vr stato was electronic was also 304

[StockoVRWagz]

Yeah If I got one Id be going newer, like VT 304 box, but need to find out what was different *back to searching. yay*

[Commydoor]

i think the VN-VP has the T700 and different computer/memcal than the VR-VS which has the 4L60E Electronic box.....youd prolly have to do a box harness and a computer swap to retrofit the T700 into your VR....dont quote me on it...might only need the memcal redone...

[ephect]

VN boxes are 700R4 - cable
VP-VQ boxes are 4L60 - cable
VR-VS boxes are 4L60-E all electronic
VT i believe are also 4L60-E but the super6's got the 4L65-E

your shiftkit goodies will fit the newer box. Trans joints recommend you only go up in models and not backward. if you have a 95 (5HDD), its recommended you replace it with the same or higher ie 6HDD, but dont go back ie 4HDD. Why you ask, minor improvements on every model.

what you have to remember is with the VT+ V6 they changed the bellmouth, as long as the box looks the same at the engine side of the box, not 100% on V8 boxes thou.

always best to chat to an auto specialist, then call another joint to confirm what their saying is true. i ended up calling 3-4 joints coz i couldnt get a straight answer out of a couple

[StockoVRWagz]

hmm will ask a trans specialist on thursday & will get back and let everyone know what the verdict was incase someone else asks this in the future.

[immortality]

i believe that the changes are one the electrical side of the box. have read somewhere before when someone fitted a later model box that the trans didn't work properly.
