Ill be needing/wanting to get my MTX75 rebuilt as my rings are not what they should be.

I have a family member that can do rebuilds but want to know if there is a different/better transmission that would go in my 05 ZX3 or if there are any improvements that can be made.

Not exactly trans but I did just put a basic clutch kit in. I know there are performance parts in this area.

Seen on here in another thread the possibility of a 6 speed.

The MTX-75 is a really good transmission. Especially with a 4.06 gear and an LSD in it.

So I googled it and cannot find any vendor selling the 4.06 because I would love to buy it for myself!
I will probably be getting a chevy Colorado here soon as a my main vehicle as I fix on my focus. Ill be pulling my transmission and take it to my family member with the shop n be asking them to put the 4.06 in it.

Did some more googling and found some references for the parts needed to have 4.06 on the fordparts and fordracing websites. also seen talk about 4.06 being final drive gear or what ever. Can change the other gears as well. Guess ill have to talk to the shop n have them do what they know is best when they rebuild it for me. Didnt know that the lsd would be inside the trans so I best have it before hand when I take it to them.

I don't know shit about transmissions. Box of gears is about all I know, besides the Focus having shitty ratios.

Terry Haines is the guy to talk with.

Hopefully mr Haines sees this post.

This mod/upgrade will be a while down the road.

Have to get a new main vehicle first. :-/

He won't. He's not much of an internet guy, especially during race season.

You'll have to contact him --> [email protected]

You changing engines as well?

AFAIK that'll only bolt up to the zetec, haven't seen anyone try to adapt it otherwise.

Throw away trannies, no replacement parts avail. for the Getrags out of the SVT's.

Differential change isn't difficult on the MTX-75 when it's out BTW, that covers the major weak point prevention on them when you go to an LSD.

Umm. So the MTX75 in a Contour has a diff final drive gear then the MTX75 in a Focus?
Idk what that means in relation to the 5/6-speed.

Only relate to the first part of the thread title, "improvements to MtX-75" - IF that gear would be preferred for the purpose.
