Convert to T5 or Tremec for 65 Mustang

[berndude]

Any advice or options, dont want to pay a fortune but I want something that will shift alot smother and easier than the T10 with the Hurst Competion Plus for my wife and daughters. I want to put in the late model T5 or Tremac and if there is a "how Too" please let me know Thanks Bernie 562-884-0788

What kinda power will it need to hold and what kind of driving? The T5 will shift better than a TKO, but the TKO's still shift pretty nicely. The TKO is WAY stronger than a T5 though, and pretty much a must for a high powered, aggressively driven manual car, or a T56.

Check the FAQ in this section there is about 4 different How to's.

I would go with a T5 unless you are going to make something putting out a hell of a lot of power.

The T5 fits almost perfectly. Some of the other 5 speed conversions required modification of the tunnel. There is no way I would do that to my car.

Links I used when doing my T5 conversion. They will answer most of your questions and explain the different options you must decide on:

All the T5 trannys look the same. They have a tag on them and the number can be referenced to this chart for its rating. You will want to look for one with a high torque rating (300 or better) .

The World Class is the correct one. It also uses automatic transmission fluid. A good check is to also open the drain plug and make sure it had ATF in it. If it is 80 weight gear lube, they are trying to sell you a NON World class T5. WALK AWAY QUICKLY


Your auto drive shaft yoke WILL fit the T5. The drive shaft will probably need to be shortened some to have .750 to 1.000 inch OF FREE PLAY. Too little and you can wreck your tranny or break the U joint and too much will cause vibration. Shorten/balance and rebuild cost $150. CHECK IT BEFORE YOU CUT IT. I decided to go with a Coleman Aluminum drive shaft from Streetortrack.com and it was 299. I have no vibration problems.

A T5 yoke has the same spline count but the part that slides into the transmission is shorter. It does nothing for the 1 inch freeplay your driveshaft needs.

Consider using a T5 bellhousing and the flywheel WITH THE CORRECT IMBALANCE so you can use a 10 1/2 inch clutch. you will also need a late model TO bearing, clutch fork, late model starter and block plate

You can use the old bellhousing but you will need to modify it. You will need a 2"x1"x1" aluminum or steel block and also the fulcrum (the piece the clutch fork pivots on) out of your early bellhousing. Mustang suppliers sell it for about 40. You can then use your old clutch

The T5 mounting bracket is needed because the the mount is about 1 inch back and the old mount wont line up. I read of 1 person modifying the old one to get it to work but he spent a lot of time doing it.

Also change out the front Bearing Retainer to a steel unit. Also change out the Tail Shaft Bushing and Seal. Both are easy to do BEFORE you put it in the car. Here is an excellent write up I used: http://www.fordmuscle.com/archives/2.../t5/index2.php

Good luck

Good info Chris66. I used alot of those link myself when I was working on my T5 conversion.

just as 67m302 says, depends on the power you're making. anything above 300HP/TQ with constant brute driving I'd stay away from a T5.
I have a T5 now and it makes me smile. The change is quite easy

[tx65coupe]

The Tremec T5 and the Ford Racing T5 can handle more than 300 hp. I think the Ford Racing one can handle 330 or so ft/lb torque. Its really the torque numbers that can tear up the transmission.
