G'day everyone,
My torana now has an injected VR V8 in it, behind this is the turbo700 automatic gearbox which is also out of the VR commodore.
I've had my wiring for the ECU completed by a mate, nothing to do with the gearbox though... all i need to know now is;
- Does the gearbox need any wiring to run properly, i've heard that if it's not wired up correctly, in time the gearbox will be destroyed.
- Also, there's a plug connected on the passenger side of the gearbox, with some kind of a sender unit, i think this may be for the speedo?
If so, that's okay because i've sourced an electronic speedo from Bernie's Auto in Wodonga for a good price.
Any help is most appreciated!
Cheers,
Rhys.

Wiring for the auto should be integrated into the harness,there will a long bit of harness that plugs into the auto.If no speedo is wired up then a speed sensor fault will come up & the engine will sometimes stall.

I've heard that if the gearbox isn't wired properly, the torque convertor clutch doesn't unlock and this is what causes the auto to fail.

Not familiar with the gearbox, but are there any vac lines to the box? If not then it relies on the ECU for information about when to shift etc, will need electrical connections.

Early vr can have cable but majority are electric,there is a loom that goes to the auto & speedo so you cant wire it wrong imo.If there is such a problem then the auto will be stuck in 1st or 2nd gear.

I have a b&M lock up converter control for sale if you are interested.
does the job well and you can change lock up speed to whatever you want.
PM me if you are interested

Sorry guys,
Popped around to autoworks where i purchased my engine and gearbox today. I was horrified to hear that the engine/gearbox combo he sold me was actually from a VP commodore.
The bastard told me it was from a VR when i purchased it, so naturally i went nuts. I suppose now finding out it's a VP th700 means i don't have to worry a lot about the wiring, except for the speedo sensor... as i've noticed as gtrboyy mentioned... it stalls after around 30 seconds of idling.
It's weird though, my mate who wired up the ECU used the VR wiring diagram, they must be similar..
the gts - do you reckon with a 185kw, 400nM torque efi V8 a converter would benifit me at all?? i don't really know much about them, how they work and what they do...
Thanks for your help anyway guys, seriously pissed off with this shop though!

It shouldn't stall after idling,it occasionally happens when you stop the car from to a standstill.
Is it a vp box with vr ecu/engine or complete vp eng/auto?

gtrboyy - From what Chris (the owner of the autoshop i bought it from) tells me it's a complete VP engine/box/ECU. Though it does have the HSV chip to give it an output of 185kW..

Hi Guys.
The 4-speed auto used in VN/VP is called a TH700 & had a cable to operate the shift points, with no vacuum modulator or kickdown solenoid. Its name was changed in 1991 to the 4L60 (4 = 4-speed, L = RWD & 60 = series). When the VR was released a similar box called the 4L60-E (it was never called a TH700). This box had all its shift controlled by a larger combined engine & gearbox computer (Holden called it a Powertrain Control Module). The connector is a large green plug on the RH side of the box. The manual transmission VRs retained the same basic wiring setup as VN/VP with a similar small computer. The small plug on the LH side of the VN/VP box is for the lock-up torque converter & this must be wired to the computer. My guess is your friend has used a VR manual trans wiring diagram, which won't have the torque converter wiring included.
On the subject of 180/185 kW chips, the VN/VP HSV chip is 180 kW, while the VR/VS is 185 kW, but these are useless unless you also fit the extra bits necessary for them to work. To get these output figures you need to fit & wire a knock sensor & fit higher flow air intake & exhaust. If you fit a 180/185 kW chip to a standard car you will end with less power & worse economy than the standard 165 kW V8.

Howdy,
Thanks Dr Terry. Do you know where i'm able to purchase plugs for the gearbox and the part where it plugs into the ECU loom? If i can get some i'll make up a new loom... i just read up on lock-up torque converters and they're quite important... Don't wanna drive the car 15km's to the exhaust shop without it!
Sorry about the 185kW i must have been misinformed.. this happens when the bloke you buy the engine off tells you it's out of a VR.
Thanks again,
Rhys.
