T5 vs AX 5 or AX15

[Zax40]

It's a little surprising to me that S-10 4WD T5s are easier to find than Jeep CJ T5s. Maybe 4WD S-10s are more common in other parts of the country than where I live. Jeep CJ owners view the T5 as weak and will often swap them out.

I have the Ford 150 type 4 speed transmission in my '31 CCPU. Of course, that is the one that is preferable to me, because I already have it. I did consider the alternatives before I bit the bullet, but I have been very pleased with it, going on 15 years now (30k miles).

The T5 has its' limitations, especially in a rock crawler Jeep or high horse power S10, but behind a 4 cylinder banger, you will never hurt it. The main reason for putting a T5 in is for the O/D and the ability to cruise. Installing a 3 or 4 speed gives you no better cruising speed although you get synchronizers.

The fourth gear in an F150 trans is an OD

I have found that the S10 T-5's and the Ford T-170's are becoming rare. Is there another option that has popped up in the mean-time? Or does anyone have a good source for these? If you say the local junkyard, you haven't tried looking.

I wouldn't build it without the lightened flywheel and the short throw shifter. These are current prices and are somewhat higher then the last build, but still considerably less expensive. You have to shorten the drive shaft and radius rods, but if you can weld or have a buddy that can, this part is a small investment.

Not everyone installs or needs both the Mitchell O/D and the Mitchell transmission. I'm not sure what "assorted extras" you are referring to?

I installed a T-5 23 years ago and when I installed a new motor, there were some issues with the original kit. I was able to find seals and an adapter to go back to using the Model A clutch disc and throw out bearing. The original kit was from Auto Restoration. Rather than screw around, I bought a brand new S-10 T-5 from the dealer for $1100. Same thing from Tremic is around $3K. We also made a bolt on reinforcement piece BEFORE we cut the cross member and reinforced the rear wish bones. Thousands of miles with no issues in 23 years and would do it again in a heartbeat.

I see a kit advertised that looks interesting in The Restorer using a "Spine Adaptor" to use a stock type Model A Disk with a T-5 input shaft.

S10 T5 Upgrade in your Model A 4 Banger

This is best done with the body off.
It assumes mechanical brakes are being retained.
A S10 4WD less the transfer case is being used.


Remove axles. A good puller needed. Mitchell sells one.

Curious, why do you have to remove the axles?

[wuga]

So am I. If you have the Mitchell puller for the drive shaft, you don't need to remove the axles and I never did. Must have been a brain fart. I will review and revise.
Thanks
