T5 Questions

NWStang · Mar 10, 2013

So found out today where my drive line goes into my transmission (believe it's the main shaft?) is wore out so my drive line is moving around. I've been hearing some weird noises and thought it was the rear end. Anyway I have a 94 GT, will 87-95 T5s bolt in? I've heard 94-95 have a bigger or longer main shaft, not sure if this is true. I've found a T5 on craigslist out of a 89 GT and was curious i it would bolt in to my car?

It will if you use the foxbody bellhousing.

However for a direct bolt in and using the 94-95 bellhousing, find one from a 94-95 V8 car. You can use one from a 96-98 V6 car as well, however they have a different 5th gear ratio and they are rated the same power level as an 89 T5.
You can also use one from a 99-04 V6 car, but you will have to swap the tailshaft and speedo gear parts from the old one to one from a 99-04 V6 T5 OR buy a speedcal for the speedo to work.

The trans doesn't do anything else wrong. It shifts fine. I only hear the noise when I'm in a parking lot turning into a parking spot or pulling into my garage. So I only hear it at speeds under 5mph. I don't get any vibration or weird noises at high speeds.

Do these kits work in stock T5 http://www.thegearbox.org/catalog/item/3819132/3531872.htm or is there a difference between the World class and a stock T5 OR is it just the internals? If it's just the internals is it worth it to buy a late model T5 and do this kit and swap my bell housing or just do it to the trans in my car?

The kit you linked doesn't show a mainshaft as included. If the mainshaft is bad too it'll really cost you more in time and parts then I would spend on a stock rebuild t5.

Describe the type of noise you are hearing?
Chrip? Clunk? Rattle?

It's more of a clunk and grinding noise. I thought it was my rear end like my track lock having problems or axle bearings as I only hear it at a slow speed like pulling into a parking spot or my garage.

have you checked out your u-joints? they may be making the clunk.

as for the grinding :-/

That's what I took it in there for originally because I thought u-joints as well. I don't trust the shop so I'm going to take it up to a local Mustang shop that I trust and have him look at it.

The input shaft is actually allowed to move around quite a bit side to side. The only problem occurs when it has play in and outwards. I made the same mistake this winter of thinking my input shaft had problematic play in it, but as long as the in/out play is non-existent you're good.

The noise to me just sounds like the normal sounds a manual transmission makes while lugging it around at low RPM's. At least, every transmission i've had from new to old has made noise at really low speeds. I'm not sure what causes this.
