TKO 600 Modifications - Page 4 - Lateral-g Forums

for those that find this thread with a search, i called liberty today and here is what i found out;

first, you can buy their upgraded tko600 for 2375+ shipping, or you can pay $500 to have yours upgraded plus shipping both ways. he said they obviously make money on the tko purchase, so the profit offsets the cost of the upgrades if you buy from them. you can also pull yours apart and ship the pieces back, and have everything done in their 2375 package (minus the front bearing) for $68. thats right, $68. you have to ship your case to have the front bearing done, and thats around $125 by itself.

so, now the problems and what youre paying to have fixed. first, he said that the linkage has a detent that keeps the 2nd gear in place and keeps it from moving too far with the 2-3 shift. the speed of the shift, plus the direction the gear is moving in relation to the cars movement builds up some momentum that the stock (weak) spring and the shallow detent cant overcome. the fix is $13. 10 for the rail mod and 3 for the new spring.

second, the shift forks ends are tapered too much and need to be built up. they weld to the end and profile it correctly. fix is $25 but you wont get your shift fork back. they have a box of premodded forks and you get one out of the box whether yours was new or old.

third, gear cones. there isnt enough friction to enable the syncros to do their job fast enough. they "scuff" up the surface which in turn creates more friction. fix, 10 for ea, 2,3,4. they also have another option which places cf on the friction surface and costs $50 per gear, but the benefits arent much improved over the scuff.

you can also have your gears polished. i didnt get a price, but its a $250 option on their 2375 trans. doesnt help with the shift, but will get you a free 5-10 hp, cooler running temp and a little more mpg.

i asked about doing it myself, and was told that if you feel comfortable around engines, you can diy. there are some bearings that need to be packed, but otherwise its just torque specs and a reassembly diagram.

i suggest you guys call and listen to what they have to say. my explanations may be off since im new to all this and it was a lot to absorb. but for the money i think its a no brainer.

Good info Tim. I am giving these guys a call tomorrow.

So Todd.... what are you thinking of doing with your TKO now?

I totally meant to ask you in Pahrump.. how did it shift at high rpm there?

Vegas69 · #34 12-13-2010, 09:30 AM

I'm going to have mine modified eventually. I just haven't talked my lazy ass into pulling it out. I have less problems with high rpm shifts than a do with a notchy 1-2 shift or 3-2.

flash, i sent you a pm back but i figured i would post part of it. liberty changed the price on their site to 2499 for the mods. this includes the upgraded 2-3-4 carbon fiber facing which was a 50ea upgrade over the 2375 price. i havent called them, but i dont see why they wouldnt have the old pricing for the original package.

and todd, just get it done so we have a reliable guinea pig.

I'm ready for someone else to be the guinea pig around here..

**Flash68** · #37 12-13-2010, 04:38 PM

Hang in there boys... I just might be the guinea pig on this one. I'll know for sure very soon.

Im still waiting..lol Lets just say if your going to send it to Liberty plan on having your car down for awhile...I think I sent the gears back to them the second week of October...

We did however forgot to send out second gear. That was flown out last week so hopefully I will have a fully non synchro'd noisy shifting trans in my car very soon...

Tim--

Actually, on the front page of their site they do list the following:

--------------------------------
UPGRADED-SYNCHRONIZED TREMEC TKO600 $2375.00
INCLUDES
Bronze Shift Fork Pads
Surface Enhancement* Processed Hubs & Sliders
Internal Shift Linkage Upgrade
Liberty's Exclusive Threaded Front Cluster Bearing Support **
Carbon Fiber Blocking Rings 2nd, 3rd & 4th Gear

**Liberty's Exclusive Threaded Front Cluster Bearing Support eliminates oil leakage from the front cap and more importantly it supports the front cluster bearing preventing the cluster shaft from improper movement. Since the stock cap is only held in place by the o-ring, it can allow the cluster shaft to move and alter shimming. This movement decreases the overall integrity of the transmission. Liberty's Exclusive Threaded Front Cluster Bearing Support corrects all of the problems associated with the stock cap.

------------------------------

This is what I am thinking of trying out.

Chuck -- good to know -- what upgrades did you get?
