Well the temps in Phoenix have finally subsided and I am now going through the boxes of parts I ordered over the summer and I'm beginning installation onto my Chassis. I have a '69 SB coupe (original 350/350hp 4spd) car and am in the middle of a frame-off. I had the original 4 spd all bolted back in place to the rebuilt engine this spring but decided to opt for a Keisler 5spd instead. Unfortunately, by the time it all arrived at my house it was too hot to work in the garage.
I started back into it today, but have hit a snag already. The instructions ask that you test shift the trans and that the shaft should spin (like the original does). Mine isn't shifting properly, and I can only get it into a couple of the 6 positions. Additionally the shaft will not spin freely in neutral.
As luck would have it, the contact at Keisler listed on the instructions was out today and by the time I tried to get in to speak with anyone else they were closed. I really wanted to work on this over the weekend, but missed by 10 minutes.
Has anyone experienced this "lockup", and what did they tell you to do to free the gears up?
The trans is pretty stiff when new. It takes about 500 miles for the shifting to free up and become smooth. Did the tailshaft spin freely when thetrans was on the ground or is it only when installed in the chassis. It will be a little tight anyhow just due to the tolerances. The old Muncy I'm sure has some miles and things are probably pretty loose compared to the new box.
The trans is still on the ground, I haven't installed it yet. I'm just trying to make sure I have it properly moving before I install it as the big print is telling me in the instructions. Thanks for the response.
Another issue is that I damaged the oil seal at the output shaft when I was removoving the rubber output shaft plug (it's torn). Any idea if that part can be ordered through NAPA? Is it a Mustang part? What year, etc...
It's the rubber "seal" on the outside that protrudes beyond the end of the tailshaft. I thought it was part of ther plug and tore a piece of the rubber. I guess it's OK?

Don't feel bad, I did the same thing I called Keisler to get a new one, they sent a replacement free of charge. It just slides and seats into the output shaft housing. Now that's what I call customer support.

Now I don't feel so bad - I guess I'll call them next monday - I felt silly after I did it :o

I had the same problem with mine when I first tried shifting it. I put it in nuetral but the input shaft would not spin very easily. In fact, although the shifter was in nuetral, the tranny appeared to be in gear.
I then ran it through the pattern a few more times (while it was still in the box) and tried it again. Same problem. I repeated the procedure one more time and it spun freely after that. I don't know what freed up, but it's fine now (although it's not yet installed).

I had the same problem.
There is a black plug around your output shaft to keep any residual oil in during shipping.
Remove that black plug and you will be ready to go. Be careful not to damage the rear seal. I used a pair of needle nose to pull mine out. We put the dexron in before installation and installed the black plug back into to keep the oil in. Dont forget to remove again before installing the drive shaft slip yoke.
... We really advise that you do not use Dexron in your TKO. It will shifter better and run quieter with the GM Synchromesh fluid indicatd in your instruction manual.
The rubber plug on the end of the tail shaft is designed to be pushed back on to the shaft when you install the yoke. That is the other option rather than trying to remove it. That method also allows you to add your lubricant before installing the transmission.
Hi Robert - Yes, I kept at it and it is now spinning freely. Additionally it will now go into all of the gears. Thanks for checking in. Is there any way I can talk you out of a new dust boot to fix the one I damaged while removing the tailshaft plug?
JohnFromVentura - it appears that I may already have the anti-rattle assembly as mine is anodized blue.
Most of the time when your tremec feels as if it is locked in gear it was done in shipping. The 3rd gear cone slides up and gets stuck the easiest way to fix this is to take a clutch disc slide it up on the input shaft and turn back and forth.
