Aussie ford 5 speed

This may not be the right place for this ... Can anybody tell me if the 5 speed BW gear box in 3.3 XF Falcons were an over-drive box. The 5 speed was only available in the 3.3 as they were such an under powered heap they struggled on a hill and had to be driven flat out every where any time you were out of town and so as a result were really thirsty.
Any one know for sure or know where to send me for an answer?
Cheers

Yes they are definatley overdrive in 5th, but incapable of handling any reasonable amount of torque, which means forget any thoughts of using it with a 4.1 litre.

Wot he said. :LOL:

Don't mess with the small BW SR 5 five speed. It needs to be steam cleaned, and a nice glass fish tank asks for a pristine specimen to act as a fish activity site...DO NOT USE!


Yes, I'm very familar with them, the XE and XF 3.3 5 speeds were perfectly geared cars, and the 3.3 went very well with them. Ratios were 3.22, 1.93, 1.26, 1.00, 0.79. With stock 3.23:1 diff, the old hump would take an XE to 155 km/h (96 miles per hour) in third at 5500 rpm, cruise at 2200 rpm at 100 Km/h, and give 27.5 miles per gallon and lay down a 17.9 second standing quarter, 179 km/h top speed. Not exactly slow...not when a 4.1 Ghia carb automatic couldn't do 18.0 second quarters.


XE 4 speed 3.3's had either 3.23 and 2.92:1 gears, and suffered a little performance wise. Gear ratios were too low at 100 km/hs with 3.23, and too high for boat ramps with 2.92:1.


Only problems with the 5speed was
1) the gearbox would break teeth if you were lucky,
2) often crack casings and spectacularly dissarange itself all over the pavement in even regular use.
3) Typical gear lever rattle set in,
4) The shift pattern was a little strange and woolly even when new.

The box is the same as the 3.3 VK Commodore one. The post 1979 to 1984 Sigma 2.0/2.6, and 200B/ Bluebird from 1980 to 1985 and Corona 'Super Responsive' ST 141 had them. The Commodore VH 1.9 and 2.85 and 5-speed had wider ratios (3.65, 2.14(1.97), 1.37, 1.00, 0.86).

:idea: If your on a budget, I'd use the stock 3.3 bell, and track down an ST-141 Corona Avant 2.4 item. Better off to get an old steel case W-50 or the much better and pricey later all alloy Supra W55 Toyota gearbox. As long as no-one tries to porn off the wide ratio SR5 Truck gearbox to you, these had the same ratios, and graft it in. They can take a 302 Ford if your gentle, and more if it has a W-50 has a full Torrington roller bearing coversion. My mate used the stock W-50 and a 1600 Celica throwout bearing with a redrilled bellhousing and a very carefully ground back input shaft spigot. Worked brilliantly.
 
I worked at a Ford dealer in the early/mid eighties and never saw a 5 speed 4.1 XF. I only remember the 5 speed looking the same externally as the 4 speed but they had 5 cast into the side of the case. I just saw a 5 speed on e-bay that is nothing like it - so it must be the box you all were talking about.

I'm about to scrap an XF S-Pac station wagon that came from factory with the following options:

4.1 EFI
World-class T5

Never seen the combo before. Drove well, even in it's dying stages.

Any links to a Borg-Warner 'SR 5'? I wouldn't want to use a box that was not up to the task. Wanna make sure what I have is what I think I have... but I'm pretty sure, even uses auto trans fluid like the world class is meant to.

P.S., I'm keeping all the good bits for my own use and throwing the body. Never seen so much structural rust.

The XF 3.3 5 speed box is called the BW 507 it's externally the same as 506 4 speed appart from the extension housing

Its not a 503 single rail with an extra gear
 
Yes, 2 types of 5 speed in XF's
3.3 had the light duty type with gears made of metal coloured plastic.
The 4.1 had T5's.
 
So the T5 is the thing that looks like a single rail but with 5 cast into the case? Yes? Maybe? Hard to shift when cold so Ford went to a different oil" Is that the one?
Cheers

Here is what a T5 looks like, and they use ATF for oil..(as apposed to gear oil)

None of the 5 speeds look like a single rail

this is the 507 found behind 3.3 holden/ford engines it has the 5 cast into the side
