Does anyone have any experience with the Gear Vendors overdrive unit for the 727 tranny?
I am really considering one, but the £2000 plus seems steep for it,
what are peoples opinions, experiences?
thanks

It is large outlay.....
Depends on what you are going to use the car for and the mileage your going to do. Plus any additional bits and pieces you have to change.

Where you been hiding then Sean









Steve aka Allkiller had a thread about a group buy

We have talked about this a lot over the last few years as well as quite recently. I think they are great and I love mine.

Hi SEAN i had an overdrive in my old transit 3000 v6 and it was great,the gear vender's one is the same basic unit made in the UK by what use to be called LAYCOCK LTD in the midlands and i think it's called a( J TYPE overdrive) they were fitted on lots of stuff in the sixty's and seventy's Even the eighty's.
On the unit there is a switch that stops it going in to overdrive in revers and 1st & 2nd gears, But you can alter that so you can use it in 2nd & 3rd gears to give you five gears. there has been some that have used it for first as well but there is no point for normal driving. The only thing that go's on the is the solenoid switch or another part of the electrical side of it the unit it's self is quite good and it does save on fuel as well as rev's.

Not if you fit decent rear gears.

Hi Sean
Have a word with 2 other black 68 owners, they've both got it fitted (surprise surprise ) and should know what parts you'd need for yours too.

Can you guess which 2 I mean?

Ive been away for a while budge, new daughter and all that new addition to the family stuff!
getting some cash together to spend on the charger, was going to throw 5k at her modifying the engine/ overdrive and stuff,and seeing as I live so far away from whats going on in the mopar scene and wont trailer it I thought an overdrive would be a good thing to have fitted.



Until I saw you hemi cuda for sale all done with no money needs spending. how much to change with the charger mate?!!!
pm me I am seriously interested

as Paulw said it is a swich that stops it working in reverse and 1st and 2nd gear, from experience please ensure this is fitted, use it in lower gears and it goes bang (been thare done that)

The GV unit can be used in any forward gear. But only over 27 mph.

It is also substantially stronger than the units fitted to British vehicles. Don't worry about damaging it unless you are making over 1500hp.

The british units really are not suitable

the only one that might be would be the LH laycock and then only in top

find a Borg warner 35 one and it will bolt up to an aussie charger gearbox (yay) (but thats no use to you)

the LH had steel clutches rather than aluminium and was used in bigger engined bigger torque vehicles

they did build a stand along unit as well...this would bolt up mid way down the tail shaft which would need to be cut and a slip yoke put on it is very rare and sometimes popped up on military spec landrovers

GKN took over and now build em for landrover/rangerover and Bananarama! (dealer fitted option for the latter i think) their units are much more like the gearvendors.

look up Laycock overdrive in google and you will find 2 UK companies that employ chunks of the old laycock workforce and tooling with all the detail on whats what. they both service the laycock versions up to LH

the later tooling qwent to GKN

P and J types by GKN got from Volvo 740 turbo

later GKN types available and i think GKN supply gearvendors

Modern landrover GKN

looks like a gear vendors

I have been in touch with GKN and they don`t do one for a 727 (although it does show it on their website).
just seen the exchange rate against the dollar and not good so will hang fire at the moment before ordering, but also considering budgies cuda!!

Put the Venders in the Cuda instead........

Brutus and Naughty Al have them
they can take 2000 HP should have you covered

I want one to

Also, why hasnt anyone tried to make a Pro tourer Cuda, Chally, whatever, using the Ferguson Four wheel drive from a Jensen FF
Saw a sad FF in Classic car news for £3000 needing total resto
