trans?

can anyone tell me if the merkur trans will bolt right in or do I have to change anything for it to fit. I have a 79' hatchback with 2.3 n/a and 4 speed

No it is not a bolt in. You will see that people who own Merk's usually change the trannys out to the Mustang trannys and it is alot of work. The Merk trannys are known to be very weak.

You could go with a T5 from a newer Mustang. I am not sure about your clutch cable or bell housing set up though.

Eric, you know what I mean [Image: wink.gif]

Do I still get a ride?

Blue, it depends on what year TC. The 87-88's use a hydrolic clutch so you would have to either swap the bell housing or figure out a way to convert your car.

The best way to do it would be to buy a TC motor and they buy everything you need for the tranny from a 87-93 Mustang.

Blueoval,

If you've got a '79 2.3/4-spd there are two trannys you could have. And which one makes a world of difference in swapping for a 5-speed.

The 1979 4-speed trannys are the 10-spline RAD unit and a 23-spline European one. Why there were two different 4-speeds used during the 1979 production year is one of those "Ford mysteries" which used to occur rather often.

If you can, take one afternoon to pull the tranny and check the input shaft. It will tell you everything you need to know.

A ten-spline input shaft tranny will swap straight away with a 2.3 application T-5. I've done it myself to my '79 Capri, replacing the old RAD 4-spd with an '85 Turbo-Bird T-5.

The only change needed was to get the right speedometer cable gear set. I didn't even need to drop the bellhousing.

A 23-spline input shaft tranny is the European 4-speed. I don't have experience with them, but I'm lead to believe that the input shaft is the same as the XR4Ti's 5-spd.
The input shaft length and mounting bolt pattern are questions in my mind.

No guarantee as to whether they really will swap without additional changes or not.
