I bought a T5 and besides what they guy told me (works well according to the guy he bought it from) I know nothing about it. What would you do? Replace the seal, crack it and inspect it, just toss it in and see what happens? What's your vote?

In reality, what would you do to get this thing going?

Replace the easy seals and stuff it in. If it ends up being a terd, you can have it back out in less than an hour, right? It's actually simple to pop the cover and look inside, so that being said- why not. I rolled the dice on mine- pulled it out of the '93 Cobra, brake cleaned it, and shoehorned it into my car. Running great so far...

I’d at least pull the tail shaft housing and then the main top cover, and the bearing shaft retainer.

I took my V6 T5 from a wrecked '98, replaced the input shaft, looked at the input bearings, didn't worry about the shims, installed with fresh fluid and and have abused it as much as ~200hp can dish out. After I upgrade the engine I'll start collecting upgrade parts for the inevitable but absent clutch dumps with sticky tires or hanging from the shifter I say they are pretty tough.

I think they get a bad rap- as I mentioned, mine’s the desirable ‘93 Cobra version mated to a 408 stroker, and 4:11 gears in a Currie 9. I flog the dogsh!t out of it every time I drive it, because why not, right? It’s still in 1 piece and holding up fine...

I have the 94 cobra version and beat mine too lol. Good shifter, bearing retainer and fluid. Just don’t run slicks if you drag race it.

Throw it in and run it, unless you have the knowledge to open it up and replace the seals. These trans. had the crap pounded out of them in the Fox body's and held up well back then. Usually took third gear syncro because of missed shifts.

Personally, I would take a peek inside, at the very least through the fill plug with a bore scope ($25 connects to your phone). I would also likely replace the seals. But if it feels good turning it, the fluid in it doesnt run out rusty, then run it.

I'd be very tempted to just try it. The hard part is getting one fitted in there. Sorting out the clutch, the shifter, crossmember, etc. Once it's all in there if you need to take it back out it's pretty straight forward. Shifter, driveshaft, speedo, crossmember, four bolts and it's out. At 75 pounds I've even swapped the one in my '67 without bothering to use a transmission jack. I can't quite bench press one back in these days but I have.

Okay, thanks for all the suggestions. I decided to crack it open to see what I’ve got inside. I spun the gears to check them all out. I found two things that may be questionable and hope you pros can guide me more.

the first one - red arrow points to what appears to be a factory defect. It doesn’t look like it was cracked or chipped in my opinion. Do you agree?

Now, the green one looks like it’s chewed compared to the similar red one.

what’s the consensus?

I'm no expert but those pictures look ugly to me. You've got a chipped tooth on a gear and the teeth on the synchronizer (I think that's what it is) are completely worn off. I'd let one of the experts here look at that before I put it in the car.

off the top of my head it looks like it would grind the 1-2 shift and really grind the 2-1 shifts. Or maybe the other way around. I'd say rebuild it. You can buy a basic kit online and the manual from Tremec is free. There are also other resources to help with a DIY rebuild too. Mainly what you are after is new blocking rings. Though the chip off a reverse gear tooth looks unfortunate I can't imagine it being a problem at all. But if it would give you more peace of mind you can replace it.

LOOKS Like you need a couple of syncro's and gear. How are the other syncro's?

If you’re looking to do a rebuild its possible. Also to note, Bob Hanlon is very well known amongst the Mustang 5.0 community for T5 knowledge, parts and customer service. His prices on rebuild parts or kits is fair too.

Check out the gear clusters and synchro images from his site compared to your internals - that T5 you have has seen better days for sure...

Time for a rebuild. The chipped reverse gear is fine, they're straight cut gears, aka noisy in perfect condition. I had one in an 83, about 20 years ago. 5th was shot and it made bad noises in 3rd. I took it apart, and carried my broken pieces in a box into Lester gear, in Tulsa OK. He glanced in the box and asked "ford or chevy" I told him ford. He went in the back and brought out everything plus some other things he said I would need. At the time it was the type of place with just a single walk way up to the counter. You were surrounded by transmissions, trans parts and axle parts of every imaginable configuration. This was before the internet became the great source of information it is. I called him a couple times for questions, but that trans worked flawlessly for years and took a POUNDING and it was the non wc, first year release version.

Thanks, do you have a suggestion on which rebuild kit? It looks like there are multiple levels (rebuild/refresh). The 2nd gear is 2.5x as expensive as other sites. I wonder why.

There are also online videos that walk you through it. Better to do it now before you install it. Plus if you get another used one it may be in the same shape. At least if you rebuild it you know what you have.
