TKX transmission installation

[Cleve]

Having a problem installing my transmission. The transmission slides in easily but stops a half inch short of mating to the bellhousing. Is it possible that the tip end of the transmission drive shaft is bottoming out in the pilot Berring. I remember seeing a similar problem a mechanic was having, on you tube, where he had to install a half inch spacer between the transmission and the bellhousing. So if any of this is possible it would mean the bellhousing didn't have the depth to accommodate this particular transmission. I asked a friend about this and he said he never heard of this. Any insight to this problem would surely be appreciated.
Thanks


Figured out the problem. The hole in the bellhousing was to tight and after a little grinding the transmission went in a the way.

Measure the depth of the bellhousing.

Can you tell us what engine, clutch and bellhousing you are using?

Did you use the plastic alignment tool when installing the clutch? Always found those unreliable. If you engage the clutch maybe it will fall right in by allowing the disc to adjust slightly and ease up the binding on the shaft. I wouldn't be using any spacers.

As quizzed, what bell housing, ect are you using?

I had to grind a bit of clearance in two spots for the flywheel in my aluminum bell housing.

Try taking a pry bar and moving the clutch fork to mesh the stub with the pilot and crank.

Cleve, you need to verify you have the correct input shaft on the transmission you are using. Tremec makes several. The information is all on their website. Best bet for you is to get a hold of Mike Forte, have all of the info ready he is a busy guy, tell him what you have and he will get you figured out. Don't assume or try to force anything.

this sometimes happens, assuming you have the correct setup, bellhousing,clutch aligned with the tool. sometimes these transmissions do stop a half inch short. but as others suggested using a prybar towards the front of the motor on the fork (as if the cable was engaging the clutch) will get it to slide in that half inch. then slowly tighted each bolt in a criss cross pattern and youre in!

I had same issue. Engaged the clutch manually with a clamp and it popped right in easily.

I unable to move the pressure plate at this time because I am using a tilton hydraulic piston which is not connected yet.

The first thing I would do is measure the depth, meaning from the bell housing mating surface to the "bottom" of the pilot bushing hole. Use something small diameter, even a straight piece of coat hanger wire will work. Then, measure the lengt of the trans input shaft from the end of the shaft to the mating suface of the trans. That will tell you if your shaft is too long.
Next, determine the diameter of the hole in the pilot bushing. Start by finding a long bolt the same diameter as the end of the trans input shaft. See if it goes as far in as the coat hanger wire did. This will confirm or eliminate the possibility that the pilot bushing is too small for the input shaft. There are, of course, other ways to measure this. You want to make sure that A) the shaft is not too long (for the particular bell housing) and B) the pilot bushing is not too small in diameter for that particular input shaft. But I do agree with the others...it is MOST PROBABLY a slightly mis-aligned clutch disc.
Most of the quality "universal" clutch alignment tools (made of metal) have screw-on pilot bushing inserts in a range of diameters, and the tool is longer than the depth of the bell housing. You can check all the measurements with that tool, if you have one

Thanks for your question. I have a 302 ford blue printed engine. I have BHF-6392 bellhousing 6 bolt, I have at Termec TKX- long input shaft ADD BNF-00400. TRF-MS17765.

My engine and transmission is still in the car, unmated. Pretty sure I am going to have to pull the engine and then I can take the measurements that you suggested. .

Cleve.... re-read my previous post. Buy the steel clutch installation tool with the multiple pilot bushing inserts. You can check the measurements WITHOUT disassembly. The only two things you need to know is: #1) The diameter of the inside of pilot bushing and #2) the "depth" from the end of the crank (which is the "bottom" of the inside of the pilot busking) to the mating surface of the bell housing. Then just compare that to your trans input shaft.
