after checking things out, i found that i was a quart low on tranny fliud. had oil all over the bottom of car. at first i thought the oil pan was leaking. i never would have thought that the NEW tranny was leaking. but it is! can't realy see where its coming from , but acording to other tremec owners, they say its the speed cable. so now all i have to do is figure out how to stop the leak? i'd lost nearly a quart of oil. no wonder it wouldn't shift right!!!

Yep, the rear yoke or seal in the TKO 600 is a problem. They do leak a little. I have gone through two yokes and 3 or 4 seals. Nothing fixes the problem. But it's a small leak and only when I have been driving the car and park it. When it is just sitting in the garage, it doesn't leak at all.
Interesting. My TKO 600 has never leaked a drop in almost 4 years. That's the transmission most of the Cobra boys are running and I've never heard of this being a problem with them either.

i'll confirm the rear seal IS a problem.. i have one leaking on my car as well.. it has leaked from day 1 and after 1500 miles, it seems to be slowly getting worse. it does not leak onto the garage floor while parked, but it slings oil while driving for sure.

I must have missed those posts. I've been an active member at CC for almost 10 years. I've only had two Tremec's but they never leaked a drop. I run ATF in them (same viscosity as Synchromesh). They seem to be less notchy and shift smoother plus it's a lot cheaper. There is no reason a properly assembled tranny should leak.

64Tux,
Here is a step-by step process to assure that the clutch is not dragging or the pilot bearing is not grabbing the input shaft. Do it in this order, and you can assure that it is not the clutch or pilot bearing.
1. Put the car in gear, any gear.
2. Start the car.
3. Depress the clutch.
4. Move the shifter to neutral.
5. While still holding the clutch depressed, try to shift to reverse.
If the gears grind, you can bet the farm that either the clutch is dragging or the pilot bearing is bad. Any other gear but reverse will not grind because they are synchronized and the gears will not engage if the syncro ring ring can't brake the gears to a stop to allow them to engage. Reverse is the only gear that will really tell you if the input shaft is spinning because it is not synchronized and it will grind if the input shaft is still turning. All other gears will act just like your symptoms, the gear simply will not engage because the synchro can not brake the input shaft to a full stop. If the gears engage while stopped, I can not think of any other reason that the trans will not go into gear when running except for a input shaft that is not disconnecting from the engine.

thanks for your input John! now that have noticed that i was a quart low on tranny lube, i'm hoping that will solve my problem. i'n not sure where its leaking. some of the posts on the forum say theirs were leaking at the speed cable, but it almost looks like its coming out where the drive shaft go in the tranny. if thats the case how do you fix that???? if anyones had this problem, what was your fix????
thanks, RAY

You will need to remove the rear yoke, fill it full of water and see if it leaks. If it does, you can use some silicone to fix it. If it's the seal, you can replace it. Like I said, I have gone through 2 yokes and 3 or 4 seals and it still leaks a little. I'm thinking there were either some bad yokes or design issues at some time that may now be fixed with the newer ones. It upset me at first since I have a new motor and no leaks other than the TKO. But I'm not willing to put any more time into fixing it as I don't think there is a good fix. Keisler said send the transmission back so they can fix it but I don't want to remove it, pay shipping, and then re-install it. Too much time, money, aggravation, and no guarantee it won't leak again. I just use a drip pan, check the fluid level every once in awhile, and forget about it.
