transmission options
 

Im excited about the V160 swaps being done @FullBlown i really am...until i tried to source one. Holy shit thats an expensive tranny! How is there no other options yet with how fast the WHP is climbing on some people cars?

I herd a rumor there's someone on here with a tremec. Anyone know who it is? Those things are all over the junk yards near me.

Does anyone know of any companies looking into gearsets for the stock tranny? particularly 4th?

Anyone?

Anything that has the Supra name with it gets priced up, I don't get it, I never thought it was some amazing car.

With patience and creativity I'm sure there are other options out there.

We had looked into producing a gear sets but it was too spendy for what it is. Another concern is the synchro in these gear boxes aren't the best either.

A complete gear set will run about 5 to 6k. I guarantee they will still have issues. The oem trans is just physically too small.

so whats wrong with a tremec? they seem plentiful and alot cheaper than the v160. Does the shift linkage not line up?

We have no expereince with the tremec to be honest. What is the price of one? You can find used v160s for about 4 to 5k.

The v160 has been tested and proven over and over. We have use them in the s2000s with great success. There are a ton of things that goes into a transmission conversion and we chose to stick to something that we know will withstand what we are about to throw at it.

these are brand new mind you but still ALOT CHEAPER. There is many varients as well, im sure one of them fits. They come in mustangs, camaros, corvettes, vipers all sorts of high hp heavy cars.

what about the getrag 5-spd from the Toyota soarer / lexus sc300? I thought they were strong but maybe not as expensive?

I'm working on something. More to come as everything gets closer to completion.

Wasn't it the Mustangs that had issues with their TR6060s or was it the Mustang's with the Getrag trans that had issues?

Getrag. It's one of the reasons i stayed away from them.

From what I've found is the ratios in the tremecs are WAY too tall for out cars even boosted. They are cheap compared to a v160 but don't like to shift over 7000rpm without getting it faceplated which doesn't help street ability.

I wanted to say something, but didn't so I'll do it now...the TR6060 linked above has laughable ratios.

Oh they're brutal. The 6th gear is like .5:1. Top speed of 235mph anyone?!

The Frozen North

a 10.0:1 ring gear and pinion might bring give you a usable 6th gear.

But you sure as hell wont have traction in the other 5 :bellyroll:

They're for cars that have, you know, like, torque.

I ment that link for the website more than that specific transmission.

It depends on the what magnum you're looking at. 6th for the 11009 is .63. As is, my first and second are unusable when running e85 @20 psi.

I was also looking into swapping in the 6 speed from the Z's. They are cheap, durable, and still in production. The gearing however killed that pretty quick. I would need a sub 3.5FD to make that work so a swap would have to include the trans, DS, FD, Axles, and clutch.

If anyone has a better idea, I'm all ears.

Yeah I tried the cd009 Nissan trans. It won't fit without cutting the trans tunnel. That trans gets wider near the tailshaft and our tunnel narrows in the same spot. Also the starter location would be interesting to sort out

Wrx trans with the rwd spool in it?

:bellyroll: Very true.

Then you don't know enough about them ;)


The MKIV Supra is relatively rare, and then the turbo version is a bit more rare...and then the manual transmission is even a bit more rare than that. Not to mention it's not a transmission they're ripping out to stuff something else in because it's too weak (I've seen first hand over 1500HP through one of them).


R154 out of a MKIII Supra Turbo would fit as well with the V160 adapter (as I mentioned in that thread). That transmission has tons of upgrade parts available (and can handle a hell of a lot if in good shape, even stock), but it's only a 5-speed..


Double overdrive transmission isn't conductive to a high reving sports car...



Those aren't Getrag, but a W58 from Aisin. Nice shifting trans, but ultimately weak (compared to the V160 and R154)



They're a licensed Getrag made in China. It's a real shame as Getrags are usually bulletproof.



Yeah, double overdrive is a bitch... 6th isn't a power gear at all on those trannies, in fact I remember them grenading in the 3rd gen F-bodies when used as such...




EDIT: After doing a bit of digging, how about the Aisin AY transmission used in the IS250 (and numerous other cars)?


1: 4.17
2: 2.19
3: 1.49
4: 1.19
5: 1.00
6: 0.84
R: 3.67


Looks like first gear is too steep though compared to the twins. I also find it weird people are having issues with the transmission in the twins as it's basically the same as the S2000, RX-8, and Miata. Someone out there has to make upgrade parts for it. Marlin Crawler would be a good place to start in that regard as they've been dealing with Toyota/Aisin transmissions for 2 decades now...


Also of note: Pontiac Solstice/Saturn Sky/Hummer H3/GMC Canyon/Chevy Colorado 5-speed is an upgraded R154 (MKIII Supra Turbo tranny). Honestly as the stock 6 speed is a single overdrive, if you're boosted and have a nice fat torque curve, a 5 speed would work just fine.

Hell, there's a Quaife sequential 6-speed for the S2000 that might bolt in. Main issue is cost as the V160 is a bargain compared to the Quaife :eyebulge:

Once @FullBlown finalises their v160 swap kit I'm going to attempt the r154 swap. You'll need to extend the shifter though because the twins bell housing to shifter distance is quite long.

The Frozen North

You have PM

bump?

Found issues fitting the r154 due to the shift linkage being along the top of the trans necessitating the need to hack the crap out of the tunnel.

Might as well go tremec magnum or the Nissan transmission if it requires cutting up the tunnel. That sucks to hear dipstick. I'll have a faced tremec before the end of the spring.

Any new info on transmissions being swapped in? 30k miles and our 4th gear already has grinding at 31k miles.

Headers, cai, catback only. Haven't even tuned it yet, though I have the OFT to tune the car. Waiting to tune it so they don't try to weasel their way out of fixing the trans.

t56 based swaps seem to be the go-to for a lot of people lately, including myself. Trying to find a shop who is interested in the project, actually capable of doing the swap, and having time for a new project is difficult however.

t56 and v160 are the two swaps I hear about the most.

i have a faceplated tko600 going in with my new motor. should be done by spring. its a custom bellhousing though

Any price estimates on complete swaps for the T56 Magnum XL and V160?

If it's just dropping the transmission and shifter assembly out and replacing with the new transmission it's not a big deal. ECU issues or anything? Will at least need the gear ratios adjusted in the computer to correct the speedometer I'm assuming. Custom driveshaft needed or does the oem one work for either of these swaps?

Thanks.

v160 swap will run you around $5k with the custom clutch, driveshaft, shifter adapter, mount, bellhousing adapter. plus $5-8k for a v160 itself

the tremec swap depends on what you do for a custom bellhousing. Im $3k into a faceplated tko600 trans and $1200 for the clutch setup. then $500 for a now discontinued Hurst shifter relocator to put the shifter in the correct spot. the magnum XL should put the shifter in the oem location, or close to it if you went with that instead. the bellhousing and clutch components would be different than the TKO though

Oh my. Someone needs to make an affordable option for this. I'll never push over 400 wheel in this car, not worth spending anywhere near 10 grand for a transmission swap.

The tremec is a nice all around box but the v160 feels a lot smoother in my opinion. Though when you're pushing crazy power levels people tend to care less about that and more about the transmission just surviving.

100% agree. the v160 is a great trans for this platform, just price and availability sort of kill it. I wouldn't do a tremec without faceplating the gears in anything that revs higher than like 5500. you get some clunking and whatnot but its plenty streetable, but not as nice as a v160 on the street

I'm seriously curious about this, because this rumor has persisted on this forum for well more than a year.

Where did the rumor start that the t56 won't shift at high RPM?

People have been swapping the magnum into the S197 Mustang for 4 years, revving to 7500 stock, and nobody has had problems. That's every bit of the revs that our little 2.0 sh*tbox engine makes and more.

People have taken the (otherwise stock) Boss 302 to 8250 RPM's with a T56 magnum XL swapped in and they shift just f*cking fine. With no internal mods.

I'll remind everybody that this is also with a larger diameter, heavier clutch disc that is harder on the synchros, and a bone stock HP of 444 (420 for the base GT)

If they didn't have problems, nobody would faceplate them. If you search around, it's very common. Hell, even tremec told me good luck when I talked to them when I said I was revving to 8500-9000. reason why I spent half hour on the phone with Liberty discussing options because they had the best reviews on forums like yellowbullet for failed synchro tremecs

And for what it's worth, our built ls2 with stock t56 shifted like crap at the track in our Frs.

If these rumors are from people who have done the swap on an 86 then I would be more inclined to say it is fabrication fitment error. I've driven three different cars using the Magnum XL from AM, one of them being my old Roush, and this is the first I'm hearing of high rev shifting issues with this transmission.

Buddy is running 750hp on a 76mm precision with the magnum XL and he has no issues, and that is winding out the 5.0 aluminator out to 7800rpm. I've personally driven the car and did not have any issues whatsoever. Shifting at redline is butter smooth. It is definitely built better than the stock mt82 and is capable of revving just as high.

Maybe its an issue specifically going in the 8k+ range. Up to that level however, my experience with three different magnum XL's have been positive.

I'm also talking about the TKO line, which is what I have. I don't own an XL
