Tremec TKX 5 Speed Transmission Installation

I replaced the Race Tuning mid-shifter with one that Tremec recently started selling. It is a big improvement.

1) It has a much shorter throw

2) The centering springs are much stiffer which makes it way easier to shift from 2nd to 3rd

3) It incorporates a 5th-reverse shift inhibitor

4) It is half the price

Hey PJ, thanks for the excellent write-up! Taking notes, specifically on your shifter stick and the new Tremec mid-shifter.

How are you liking the TKX? My TKO has to come out because 1) it’s whiny and I’m tired of hearing it complain, and 2) I beat on it until it broke something inside the bellhousing this morning. Im thinking about upgrading to a TKX or maybe Magnum while it’s out, curious what your experience has been like with your transmission, especially shift quality and noisy-ness (not my TKO’s strong suit).

Thanks -Chris

Hey, Chris. I don't have any experience with the TKO, but I'd say the TKX is pretty quiet. It does make a very slight high-pitch whine that I can hear when coasting. It's not distracting though. Shifting is reasonably smooth. The 1-2 shift can be slightly rough when the transmission is cold, but it smooths out after a couple of miles. I have found that the TKX doesn't really like to be shifted fast and aggressively. It likes a slight pause before shoving it into the next gear.

Out of curiosity, what fluid are you using?

I found this on the ShiftSST site:
"TREMEC approves the following fluids for all of their 5 and 6-speed transmissions: TREMEC HP-MTF, Pennzoil Synchromesh, Dexron III/Mercon ATF (non-synthetic), and Mobil 1 ATF. We recommend the ATF fluid for break-in and the TREMEC or Pennzoil fluid thereafter."

I bought Mobil 1 ATF for mine to start with and was planning on Synchromesh for later, but haven't filled it up yet.

I am running ACDelco Synchromesh which is one of the fluids listed in the installation instructions from SST.
