Will the TKO fit in replacement for the T45 on a 98 Mustang GT? If not do you carry a trans that will?

AaronP

So if this transmission is a direct fit for the 5.0 windsor engine, right? I'm considering swapping a manual transmission into a 6th gen mercury cougar, which has the windsor.

LMR

  • While this transmission is a direct fit for the 5.0 Windsor engine, we are unable to confirm fitment of this transmission into a 6th generation Mercury Cougar as we have only installed these transmissions into Ford Mustangs.

Which transmission would be a better choice the .68 or the . 82? I'm running a 3.73's in the rear end.

LouisJ

  • When choosing the best Ford Performance Tremec TKO 600 Extra HD 5-Speed Transmission for your vehicle, the difference will be in the 5th gear or overdrive gear. the .82 will offer better acceleration in 5th, the .68 will offer decreased RPM's and fuel consumption in fifth gear.

Will this transmission hold 600 flywheel hp or 600 rwhp

Foxtrotbravo

  • Hello! Ford Performance does not list an exact horsepower rating for the Tremec TKO 600 Extra HD 5-Speed Transmission. It is, however, capable of handling 600 ft/lbs of Torque

For a 1990 LX, will the driveshaft length have to be changed when using the TKO600 in place of the stock T5? I understand the cross member, tailshaft yoke and clutch will be changed, but will the stock length driveshaft still fit?

Anonymous

  • You should be able to use your stock length driveshaft when installing the Ford Performance Tremec TKO 600 Extra HD 5-Speed Transmission. However, you would need to swap out the yoke for proper fitment.

Is there any clearance issues with the tunnel? And does the shifter end up in the stock location?

WBNotch

  • Depending on which year this is being installed Ford Performance Tremec TKO 600 Extra HD 5-Speed Transmission there should not be many clearance issues if any. The shifter does indeed end up in the stock location.

    Well what can I say there's nothing like a brand-new transmission Out the box .. If you're running a car with a lot of HP and torque especially a Mustang with a T5 .. You know chances are your T-5 not going to last long . I must say this transmission has a totally different feel it drives a lot smoother than a T5 in my opinion .. Overall it's very much worth it It does not pay the purchase another T5 spend the extra get the bell housing and new clutch crossmember and transmission .. Also remember to use GM synchromesh transmission fluid ..

    Purchased for Cobra Roadster Project

    The transmission was installed on the engine before being installed into the chassis as a unit. Prior to installation, the tail shaft housing mounting lug was removed for cross-member clearance. The transmission was well packaged and palletized for protection during shipment and arrived without damage.

    Awesome transmission

    Love this transmission. Only had it installed a couple but I'm already in love. Still got awhile before she's fully broken in. I read some reviews before saying the Tremec TKO 600 was a little rough on shifts. Especially during break in. So far mine has been butter all the way up to 5th. I don't know enough words to describe how great it is. Point is, I love the transmission and recommend it for anyone wanting a great street transmission. If you have the money for all of the required upgrades. Then it's definitely worth it.
