- Hello, and welcome back to the channel.
I have finally decided to pull the trigger on a new transmission my for 03 cobra.
I have stated many times, that my personally my biggest gripe with the Cobra has been the shifting smoothness. From everything I have read and heard, this IS THE FIX. The T56 Magnum is essentially a TR-6060 which is the go-to transmission for the Viper, Corvette, Camaro, GT500, and many more high horsepower RWD applications.
I also talk a little about the internals, drivedshafsts, and crossmembers.
Also, hit upon my home security camera setup. They are 4MP Hikvision ColorVu
I would love to go Magnum someday. Soley for the shifting effort as mentioned. I had a 2008 GT500 before my 2004 Cobra and that TR6060 was the cats ass, even with the stock shifter. Buttery smooth. You’re gonna love it man, happy to see that car get such a nice upgrade to compliment everything else!
It is the final piece
I like the stiffness of the stock trans 🤷🏼♂️ it’s part of the terminators character. You start changing the big stuff then you losing that terminator feel. That’s just my opinion tho, I like more of a stock car! Keep the killer vids coming!
And here I am 9months later with a magnum transmission 😆.
Hope the comments help the algorithms 👊🏼
I love my T56 Mag...really a TR6060..great box...some mods were needed..1) driveshaft shortened 1/12”..new yoke..and high strength u-joints$ 375.00..2) trans cross member slotted..did it at work..didn’t know about Stifflers...!..3) electrical plug is on opposite side..so wire harness had to be lengthened...that trans goes through gears like a hot knife through butter..awesome shifter..no missed gears...cool vid...
What did you swap it into?
2003 Cobra…
No more missed second gear in burnouts! :D
Great point!
Cant miss second if you start in second ; )
@intervention302 I really appreciate your videos man. Being a cobra guy I have learned a lot from your reviews. When buying the T56 Magnum swap kit from Lethal other than the Stifflers cross member is there any other custom add ons that you would suggest buying?
Thank you
I'm currently running a 6R80 in my 03 and looking into the T56 magnum. I bought the car last year with the auto in it. Got a lokar select shifter and using the US Shift Quick 6 controller for it. Works great! barks 4th gear at 100mph. tuning it is easy with the controller. But it still isnt a manual. They suck when traffic is backed up but the overall feeling of driving with a manual is what I miss.
That is kinda my feelings. I know it would be faster with a 6r80, but the T56 magnum seemed to be the better choice for me
The other guy take a leak around the corner?😅
Very informative video ty. What’s max power the magnum can handle though? 7-800? I’m building an ‘03 with 78mm turbo. Can I run this trans or am I going to have to go auto 😢
The only drawback IMHO to the Magnum 6 speed is that MGW does not make a shifter for it and the Magnum shifter is so-so. You also need a shorter driveshaft but I bought the complete D&D Performance kit for mine which included the shaft & bellhousing. Stifflers crossmember is an excellent idea too because it not only fits but it comes with various adjustment grommets which you may need for proper alignment. It is critical that when the magnum is installed to get your pinion angle checked and if necessary adjusted(especially if your cobra has been lowered). I skipped this step with mine and had severe driveline vibration issues.
Where did you purchase yours from? And how did you fix the pinion issue? Is there some sort of tool required to make sure everything is aligned?
@@racequad9 You need an experienced mechanic to make sure the kit is installed correctly and pinion angle is right. I bought my complete Magnum kit from D&D performance.
@@tomkjr1 thanks man. Mind if I ask what paid?
@@racequad9 I bought my kit almost 5 years ago at around $4K. Prices are higher now.
@@tomkjr1 Nice man. What were you able to sell your stock t56 for?
so your stock t-56 handled all that power?
Yes the 2.97 is trash in my opinion cause 1st is shorter 3rd and 4th are taller and fall on there face. The 266 178 130 100 80 63 gears are essentially perfect . look up a stock c5 zo6 speedo vid you will see what im talking about. The early 5th gen ss camaros had similar gearing in the manuals, its terrible. Some of the ls3 vettes had the shorter first gears to you have to be careful when buying them. The z51 option c5's had it too. I despise the 2.97 t56
I had my magnum shipped through fedex in a pallet way unprofessional of ups handling that trans
Does yours have the “box of rocks” gear rollover noise at idle with clutch pedal disengaged? Don’t lie! lol jk 😂
But really,just finished installing mine and on idle the gear rollover noise is kinda bad,pretty irritating considering the price we spent on these transmissions and from I hear and read its normal,waiting to see what D&D says about it..
It does actually.... damn
I thought my clutch fork or pivot was slightly out of order
@@Intervention302
Check out grannas racing he has a video explaining the noise
im about to put this in my foxbody
it seems like the best option out there
Did you see the smashed in box. They don't care is right
What trans fluid did you use? Doing swap as we speak.
Lube
Curious where you bought the trans from and what shifter did you go with?
Did you get a new clutch
Did you purchase this from Lethal Performance? They also have upgraded magnums from RPM that have some upgraded parts. What are your opinions on their level 4,5,6, and 7 magnums from them?
Regular magnum has been in the 8s. It's fine.
Bought from Lethal
@@Intervention302 if you could upgrade 1 thing from the magnum, what would it be?
Is it still for sale?
Too he honest man.. 3k is a STEAL for that transmission new!
Especially in today’s age
Did you use a different bell housing or stock bell housing?
Stock works
@@Intervention302 thanks for the info. Doing the upgrade now.
Can you help with how I can tell if my 03 has a tune or not
there would be a few ideas to look for I would think. If youre concerned you need to bring the car to a real tuner and have a dyno pull done to check the car's health
Does tremec require a t56 core?
no core
sell your T56 on the used market
I had my t56 rebuilt and added all the goodies but it's still notchy when shifting....wanting a smoother shift. I might be better off selling it and getting the Magnum.
What gears are you running?
stock 3.55
@@Intervention302 what’s your thoughts on gear changes? I’ve got a high hp cobra and was thinking 3.73. Am I making a mistake? Any advice on gears?
@@jbsvt9126 I too am running the 3.55 at over 900 wheel I will not be changing the gearing. infact I plan to run a 28" tire make each gear little taller if you will. If you were around 500 wheel and had no intention of going further 3.73 maybe worth it. With the hp/tq numbers in the 900s/800s taller gears win out imo.
Omg auto transmission. Thank god you didn't. Id rather hive up 50 hp then but any sports car with an auto.
At one point I wanted to be fast. An auto is the easiest way, for the driver and the car. But I decided I want to have fun as a street car
