Hello, I'm working on the same setup on my 70 Cougar, do you recall what size bell housing bolts you used?

Gear Vendors also make a direct kit that fits the Cougar with the FMX as a direct bolt in.

Hi David - There are a lot of things to consider - in this application (Ford Falcon) the Gear Vendors is far better than an E40D. With the F250 many more possibilities and some pluses depending on terrain and load where the Gear Vendors is better and the lockup not so much. But yes if you are diesel trying to get down to 1700 rpm then you need a lockup. It is why we have sold thousands of Gear Vendors for the E40d to gear split ratios and why the tuck now has a 7 speed automatic in it stock.

Hi Rick, I didn't mean to suggest an E4OD in that application since it might not even fit under the floor of a falcon. I actually know a fellow member on oilburners.net that has an E4OD, 3:55 ratio and GV overdrive. Its the only truck I know of similar to mine with an even taller final drive ratio. I have a 3.08 rear end, but no aux overdrive. Not sure if I would really need 7 forward speeds since I already have 2 top gears. At freeway speeds the old diesel is turning 2300 RPM in 3rd and 1600 RPM in 4th.

I tried the Gear Venders in my Mustang years ago and the Over drive is not enough. i switched to a T5 with a .68 over drive ! this worked better with my 4.11 gears than the .78 over that the gear venders had! The gear venders id too expensive to not have a choice of over drive ratios, It cost more than my complete T5.

@@mylanmiller9656 why are you using 4.11 rear gears? Are you drag racing?

@@musclebone7875 my car sees both Street and strip, I run short slicks on the drag strip and tall tires on the high way! I got the best Drag times with 4.86 gears and 10'x 26 x 15 slicks but it was not street able!

+Ryan Denney Hi Ryan - You would not if you ever tried a Gear Vendors. A 4R70 is a wide ratio trans that even with control of the lockup will never give you the close ratio of 6 actual ratios from 2.48 to .778. Power handling and reliability far greater with the Gear Vendors setup. If you ever get the chance to take a ride in a Gear Vendors equipped car you would then instantly feel the difference.

+Rick Johnson How does the GV know what gear the C4 is in? Without some sort of feed back from the C4 trans you'll likely never see all 6 ratios during a steady 20% throttle accel. I suppose in a fairly stockish 289/302 in a 3500 lb car you see 2 or 3 gear splits on down shifts. A late model roller 306 on 14lbs of boost doesn't have time for the trans and added over drive until to sort out who's doing the shifting and how often. Modern electronic transmissions still have there place in the performance market. The 2k price tag for a GV would buy lots of 4R70W parts. The GV unit will out last most C4s anyway.

Hi Makitta - Do not know how I missed responding to this earlier - it is a common misunderstanding about Torque Converters. When cruising steady at 55 as you point out you are only making about 50hp no matter how much engine you have or you would be accelerating. at 50hp at 55 mph or even say 100 hp at 80mph any decent converter is going to be very close to full 1:1. The stall only comes to play if you have the 400hp or so you built the converter to flash to. Call us anytime to discuss in detail. It is a great subject which we have proven for 35 yrs. We have now 5500 stall converters in cars like Jeff Lutz. Tom Bailey, Larry Larson, Bryant Goldstone - all doing 2000 rpm at 70mph in overdrive on the street with cars that make over 3,000hp ( of course at that moment of cruising they are really only probably at 65 hp during steady state cruising). The factory lockups on newer cars are to net another 5% in fuel economy because CAFE standards mean millions of dollars in penalties otherwise. So they want to run 1700 rpm at 70 and thus get every once of fuel economy possible. Our customer cares about 25% better fuel economy and Gear Vendors will get you that but our customer does not prefer the downsides of a lockup and its expense for the minor benefit it offers on the epa test cycle.

I would agree with the second option as the stock trans is a CAFE built wide ratio and lockup - not a very performance oriented package - all about EPA. Call us at 800-999-9555 and discuss you use and engine, rear ratio etc.

Hi Jay. What tire size and rear ratio do you have in it now? What’s the vehicle. Auto or stick?

@@gvrickf1 its a 79z 3.73 28' tire 4000 stall TH350 wanting to go 4.10 with a GV

Our speedo wire input is to our signal generator at the overdrive. We put the correct ratio speedo gears in the overdrive for your rear gear and tire size. You would typically use that with the included ford speedo adapter to drive your dash but it has no bearing on the overdrive function if you do not screw in your stock speedo.

Yes

I am not certain but my grand mother had an earlier sprint with automatic.

The 63 1/2 Sprint came with the 4 speed BW or the 2 speed auto hooked up to the 260 V8. Mine has a 302 with a C4. I dropped it off at the El Cajon Gear Vendors shop today for the install.

Shifter button up on the shifter is also an option. When we use a floor mounted dimmer then we move your stock headlight dimmer over about 5 inches toward the pedals and up about 5 inches higher so you can still reach it easily but not bother your dead-foot position. Sounds odd to shift on the floor but it actually works very well because you can grab the overdrive gear manually with both hands on the steering wheel even when cornering at speed like from 2 to 2nd over and back down to second - like on canyon roads that are fun to drive.

2695.00 for the complete kit in the U.S. lower 48 shipping is 55.00 optional stock Mustang t-handle with button on the dummy side is 85.00 . That is the whole deal with all options. No mods to tunnel etc. Watch the 65 mustang video on our website. Give us a call to discuss your car exactly. Nick at ext 117 or Rick at 154

Wish it was close to this price down in Australia...

+Ronnie Mata Hi Ronnie - Yes the Ford C5 and C4 are the same transmission and installation for our product. Call Nick here and he can answer any other questions.

nice thank you for that
