I Just Got A Tremec TKX Transmission: Here's What You Need To Know

[@davidtuck2205]

Thank you Nick for the Shout-out, we're all excited to see the videos of your install on that sweet Impala. MDL is all about 3-pedal life here and helping customers just like you at Classic Nation. The TKX is the hot new next-gen 5-speed for sure! Looking forward to seeing rip through some gears.

[@camtwo1466]

First thing everybody who buys a TKO of a TKX transmission should do is remove the shifter plate and take some molybdenum based grease and grease the shifter end and the double springs that controls left and right motion of the shifter. Just thinking that the internals will spray lube the upper half of the transmission is wishful thinking as the parts were bone dry and the trans is filled to proper capacity and properly angled too.. Doing this will make your transmission shift so unbelievably smooth and not so stiff feeling.Youll still feel where neutral is but NOT as much!!! I put 5000 miles on my TKO600 and the spring tension on the shifter felt stiffer when engaging into first gear than 5th or reverse so I took off the shifter and found that lack of lube was causing my pressure washers to grind into the aluminum body of the shifter housing and causing the springs that control left and right motion to bind up inside each other due to being bone dry.. Whats not noticed with the eye is that the lug that attaches to the shifter has a slight angle to it when its seated correctly the angle is angled down towards the drivers side of the transmission so if you have to pull to the left a il more abnormally than you feel like you should be needing to do so this is what I was experiencing until I turned the cube thats attached to my shifter 180 degrees , greased the shifter rod that makes contact with the dogs, greased the springs and viola I now have a sweet shifting transmission...

I have an 81 GMC C3500 manual 4 speed and have been thinking about a T56 or TKX. Subbed. Thanks for documenting your work.

[@Silencer84]

Did you choose yet?

[@miguelsouderado3459]

@Silencer84 Not yet. I think I am leaning towards the Chevy connect and cruise with a 572 and a T56. Probably am a year out from that. Too many other projects.

looks good. I am wanting to do that same trans in my 1970 F100. Currently installing an Old T-5 into my 65 F100 with Modern Drive Lines Conversion Cable kit for 61-66's. I will post a video soon. rock on.

[@Coolride1000]

Wish they would have had this available when I put my tko in my 71 Chevelle so I would not have had to enlarge the transmission tunnel. Should be fun in your Impala.

[@aDumtreeF85]

I bought a TKO a month before the tkx came out. Now I’m trying to get the TKO in a 69 cutlass with a 455. Converting auto to manual.

[@browardbackpain]

Very good transmission. Have the 5 sp in my '69.

[@RussianbillionputtingWorth]

Your shifter Spot can be turned 170° TK5 TKO lots very good for Mustang

[@72fasterthanyou]

I have a TKO 600 with 4.10 rear gears. 1st gear seems a bit too low for me. I think I should go to 3.73 gears... I hope they solved the 2-3rd upshift issue... the synchros lock me out above 5k rpm. You have an awesome looking ride!

Size is definitely a huge benefit over the T-56, that thing is nice and compact!

[@davidspencer2333]

Nice video! My TKX arrived earlier this week and I pulled the Muncie out this morning from my '68 Camaro. I purchased mine from Silver Sport Transmissions and they too are great! I'm looking forward to your install. Are you going with a mechanical clutch and traditional throw out bearing, or a hydraulic? I have a QP rear axle with a Ford 9" center section and am going to go with a 3.70 ring and pinion to work with the close ratio TKX...

[@Scorpio_Slayer]

Does this transmission handle 4wd 3/4 ton big block power upgrades? if not what's recommended for big block manual 3/4 ton, my build will be based off the 454 80s Chevy truck platform. I just want to make sure it handles the weight of those old trucks an still lets me put power down, Thanks for any info.

[@mikemaguire5507]

Does look like it would fit in my 66 Chevy 2. The big AutoGear case I got now barely fits . And that shifter no way without cutting up my transmission tunnel and that ain’t happening

[@jagco2594]

What parts needed to make this with work chevy 350. Clutch, pressure plate - they make fingers that don't stick out some much, flywheel. 2 peace main, What's the specs on the bearing fully close. I need to lose 0.44 spacing. To use a hydraulic bearing. 1.710 bearing closed press in on the clutch fingers.

[@kennethmcleroy221]

I’m doing a 1972 Buick GS. From 700r4 to a Tremec TKX with hydraulic throw out set up. My question is mostly about the pedal assembly and all the different ways to set the shifter so I can cut the hole out in the right place. I’d appreciate your input. Thanks

[@cfrank925]

Excited to see the install.

[@or-ian6973]

Keep in my mind 600tq is at the flywheel. Overall it can handle good power but nothing crazy. I’d like to hear real world testing though.

[@randydarcey2947]

Thanks for splanning the ratios

[@dougm2617]

Hey Nick! Did you make some more vids? I’m curious what size driveshaft you used

[@misterwalrus4139]

quick question. I don't know much about manual transmissions. does the TKX have reverse lockout and how does it function? I have a '66 Mustang with a factory 3 speed auto that is about to give out and wanted to swap to a 5 speed manual. the manual trans Mustangs back then had a reverse lockout mechanism that worked by pulling up with your fingers on a metal fork attached to the shift lever. I was wondering if I bought a restomod 5 speed lever, would the reverse lockout fork end up just being a dummy fork that doesn't do anything.

[@faisaltalal9027]

I am in the process of purchasing the Tremec TKX Manual Transmission for my Ford Mustang 1992 LX with an LS swap Engine . there are two types of TKX Transmissions available GM and Ford. I want to make sure I choose the right that fit the LS Engine . Additionally, I have seen that there is an LS bellhousing option as well as Clutch LS kit .Could you please advise me on which specific type I should purchase for my vehicle? Ford or GM ?

These look like the way to go for allot of people; strong possibility I’ll pick one up for a project. However, I see several videos where people do some comparisons to the magnum, like you did when you mentioned you just don’t need two overdrives. Is that it, is there anything ells? Is a magnum better in 80mph freeway cruising, or are we only talking about a benefit over 150 or something? Thanks for the video!

[@MrYz250fman]

I havnt been able to find prices on them. What did modern driveline charge you for the trans and shifter?

Never heard of anyone putting a trans cooler on manual trans. Its not designed for one, you would have to port it for hoses and install a small pump/

[@time_on_target]

@@cuzz63 The TR6060 that came in my GT350 has an internal pump and a trans cooler. Same thing with the Camaro SS 1LE's, ZLI's, and I've got friends with Boss 302's running trans coolers. HPDE's often run 30 minute sessions and having the cooler would prolong the life of the fluid and the transmission.

It looks very similar to the TKO tail housing so I would bet they are using the same slip yoke. If not it’s kinda sorta sounding like… why not upgrade what ya got. Unless what ya got is the useless for the street TKO
