What 5 spd for AMX

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   The torque ratings are:
T5Z: 330 ft-lb
TKO-500: 500 ft-lb
TKO-600: 600 ft-lb

The difference in the 500 and 600 is the low gear ratio. The 500 has 3.27:1 and the 600 has 2.87:1.

The T5Z has 2.95:1 as scott mentioned which is part of the reason it's stronger than the standard Ford version WC T5 with 3.35:1 first.

	great info guys, much appreciated. Thanks for the component / price breakdown Scott. That’s helpful. As much as i want / need a lower first gear I’m thinking anything over a 3:1 might be a bit too low (I have a 3.73 rear). It does sound like the T5 variation would be the best route to go from a cost perspective. Scott you used $2k for a new transmission-where would you get one? I assume the other components were sourced used? I have a fairly new Centerforce clutch in the car now so could probably just replace the disc. This is something to be considering for this winter - if I keep the car. Been thinking of moving it along to get something a little easier to drive.

	I got my new T5 Z from Summit. At the time they matched the best price I could find, & shipped it for free. Summit currently lists two T5 Z, one thru Ford Motorsports, the other American Drivetrain. From what I see, they are the same transmission, but the American Drivetrain is $100 less. Summit currently has a $100 off deal if you buy online & spend $1200 or more. I sourced a used bellhousing. The trans mount & yoke I got new.

	LGT 700 looks like 700 ft/lbs torque. Wide ratio version has a 2.97 first gear, so it should be workable. https://www.5speeds.com/legend/LGT-Brochure.pdf The only site I found mentioning a price said "$3500-5000". That's a big range! I suspect the $5K is for a full kit with clutch and bell housing, $3500 trans only. Here's a good break-down of available five speeds, and where I got the pricing on the LGT 700. It's dated April 2016 though... https://www.powerperformancenews.com/tech/the-world-in-5/

	TKO 600 from silver sport. Expensive but turnkey. Hydraulic clutch and throw out bearing. I changed out the master that they sent (3/4" bore) with a 5/8" bore to lighten the clutch feel as well as give it a little more feathering. Everything lined up and no modification to the shifter location to speak of or the cross member or driveshaft.

	This is one of those how high is high questions: Steel flywheel? Scattersheild? Matching blockplate? What clutch? What clutch linkage? High rpm shifting upgrade? What input shaft? What yolk? Upgraded driveshaft? What shift lever? Just cruising most of this stuff can be basic or use stock. I went with a proper scattershield and matching blockplate, steel flywheel, Liberty shifting upgrade, Mcleod "Street Extreme" 10.95" clutch, short Ford input, 1330 yolk, then went to a complete new 3" driveshaft with a 1350 billet rear axle yoke, and a short shift lever. But this car has decent power on goes to the track on occasion. No wonder there can be a range in price.

	Fanatical Performance in Wausau Wi. Sells t5's. That's all he does and can build one that handles more torque.

	I have the T5 with the G-Force case and other upgrades. I have had it for several years and I autocross a few times each year in addition to driving like a hooligan way too often. There may be other options available now that were not out there when I purchased this, but I'm happy with it and it's not failed. It's sits between my mild 401 and the Moser 9, so truth be told this is the weak link in my drive-line, and it's working so far If this does fail, I'll probably go with the legend gear LGT-700. had that been available when I upgraded I may have gone that direction. If I recall the LGT-700 is a bit pricey, but my G-Force stuff wasn't cheap either. The T5 transmissions are compact and fit easily into these old cars which is a major positive. The G-Force Case and internals are stout pieces. Edited by 343sharpstick - Jul/19/2019 at 12:23pm
