just installed tranny

[torch93]

hey guys quick question, i just installed a t 5, and when i push in clutch and try to put into 1st it grinds a lil, i haven't drove it due to h pipe not installed but i added the 3 quarts of tranny fluid and tried to go to gears and notice it.. could it mean that i need to drive it to get the oil mixed around or tranny bout to go?

Is this transmission new?

And is the clutch completely disengaging?

id be willing to bet you need to adjust the clutch

Clutch adjustment
Do the clutch adjustment first before considering any other problems. With the stock plastic quadrant and cable, pull up on the clutch pedal until it comes upward toward you. It will make a ratcheting sound as the self adjuster works.

Clutch pedal adjustment with aftermarket quadrant and cable: I like to have the clutch completely disengaged and still have about 1.5” travel left before the pedal hits the floor. This means that I have only about 1” of free play at the top before the pedal starts to disengage the clutch. Keep in mind that these figures are all approximate. When properly adjusted, there will not be any slack in the clutch cable. You will have 4-15 lbs preload on the clutch cable.

It's a used tranny wait a " rebuilt tranny" I only switched the tranny and left my old bell housing on so I didn't take off my clutch, with my other tranny it didn't do it.. I was seeing if it could be low on tranny fluid or bad tranny?

ok check this, i just got back from a cruise with new tranny and gotta say it holds really good. now that 1st gear grind i was talking about is only when i quickly throw into first from neutral .. but if i go into 2nd and then throw it into 1st pretty quick (at a stop of course) or if i just slowly put it into first then it will not grind at all

Check the clutch pedal adjustment, even if it didn't seen to need it before you replaced the transmission. It will take you 1 minute with the stock adjuster and maybe 30 minutes if you have to jack the car up to adjust an aftermarket adjustable clutch cable. A setup with a firewall cable adjuster will take less than 5 minutes.

The other alternative is that the transmission syncros are worn out and need replacing.

Cable adjustment, bad syncro or pilot bearing.
Pilot bearing is the most forgotten thing to check when getting grinding gears.
When you push the clutch in, the desired effect is for the flywheel to keep spinning, but the tranny input shaft to come to a rest. If the pilot bearing is bad, it will keep the input shaft of the tranny spinning and make the syncros work harder to stop it from spinning.

He's absolutely correct.

I had a cheap Chinese (Advance Auto Parts) wear out and damage the pilot bearing surface. The transmission was hard to shift and ground in almost every gear. It took a new input shaft, pilot bearing and a lot of sweat and effort to remove the trans, replace the input shaft put it all back together. There was $175 worth of parts and $25 to get the bearing pressed off the old input shaft and on to the new input shaft. I learned never to go cheap on pilot bearings...
