I purchased new TKX 5 speed , I have a little over 1000 miles on it, it has a slight grind going into 2nd and 3rd. I can down shift into 2nd or 3rd no problem. I have zero issues going into any other gear or reverse. New atc clutch and dialed in the bell housing.
Any one else have similuar issue or experiences. Purchased from SST- last thing I want to do is take this back out again for obvious reasons.
Did you replace the break in ATF with the synchromesh after the 500 mile break in? My Tremec TKX the clutch pedal must go all the way to the floor or it's hard to get in gear. Even the floor mat can cause problems.
My old Tacoma was notorious for being notchy going into 2nd gear. I replaced the factory fill with Red Line synchromesh fluid and it smooth it right out.
Yes I did contact them, its under warranty, it's removing it that's the real issue PITA
Just wondering if anyone else has gone thru the return process and if the issues were repaired correctly.

Have you reached out to Silver Sport Transmission about the issue?

Shifting is frequently, but not always a clutch issue.
How is your free play off the floor?
How well does it shift into reverse, (non-synchronized)?
The trans should spin-down in 2-5 sec and at that point go in reverse without a clunk.
If it does not, the clutch is dragging.
That's usually the best test for enough free-play off the floor.
And if that is ok, but it still shifts badly, it is not the clutch, so it must be the trans.
The TKX has double-cone carbon-faced synchronizers. So they should be very smooth, but they can still get beat-up. You can see the carbon friction surface on the inside of the center cone, and brass on the other side.

I have had issue in the past with several different pressure plate manufactures where I had to push the pedal all the way to the floor, Lars ( Thank You ) has an excellent post on the amount of peddle throw needed to fully engage the pressure plate, thus why I went to the ATC pressure plate which had the least amount I found required. For those with issues double check all your clutch pedal linkage very little wear makes a big difference.
My clutch peddle is just fine, lot's new parts & no issues ever shifting into reverse or any other gear except 2nd and 3rd which share no common sync ring or slider ect.
Just thought i would reach out to see if any others had to return there TKX or had miracle cure- LOL. I was thrilled installing this new tranny, even at 65 years old, I have put many in over the last 45 years, taking this one out of my 68 is extremely depressing at best.
I had a customers car we put a new TKX into this summer. While putting test drive miles on the build, (several hundred) the shift to 4th gear starting grinding badly. Three of us driveing it first thought it was our shifting. It got worse. Pulled trans out,, shipped to SST,, got new replacement no hassle. Car is operating fine ( 496hp,, 520tork,, ) in the hands of customer now.

Several years ago I put a TKO 5 speed in my 79 and had a grinding noise in third gear. SST was delivering a car to Atlanta and stopped here in Chattanooga on the way back and took my car back to Knoxville. They couldn't determine the issue so put a brand new transmission in it at no charge. I can't say enough good things about SST.
