T45 Source experiences?

[4n_eatr]

I think my trans is getting tired. Starting to make some funky noises. I have a quote from the T45 source for about $1500 to completely rebuild it to handle at least 450 lb ft of torque. Has anyone had any experience with their rebuilds? I'd like to have a t-56 but not really looking to modify anything just yet. Plus I can make payments by getting it rebuilt, lol. Somebody brought up TKO to me but I'd eventually like to have my engine revving to 6500-7000 so a TKO is out.

[cstreu1026]

I know Zak and Jim and you won't be disappointed. I also have a few friends running their transmissions and are happy. Out of curiosity why is a TKO out?

[4n_eatr]

Mike was talking about the TKOs but mentioned they didn't like to shift at high RPMs. I'm going to wait and see what my tq #s are when I get the car dyno'd. I should be pretty close to the 325 lb ft rating of the stock t45. I'd like to just save money and rebuild the one that's in it to stock specs, but not if I'm going to have to rebuild it again next year.

[cstreu1026]

Supposedly with carbon fiber syncronizers they'll shift at higher rpm but I don't know anyone with first hande experience there. I went the guaranted route with mine....faceplated gears.

[4n_eatr]

He mentioned the carbon fiber upgrade, but that just adds even more money into it. An I'd like to keep this as a daily driver and I won't be making the power levels you are so faceplated gears are out, lol.

[cstreu1026]

As long as you aren't planning on power shifting at high RPM almost any transmission will serve your needs. I can't remember but are you a member on modularmisfits.com? If so talk to madi98gt or cool hand about their t45s hey both love them.

Yeah I am but I haven't been on there in a while. Ill have to send them a message. Thank you.

T56 FTW!!!

[4n_eatr]

T56 FTW!!!

Oh trust me, that's what I want and what I will eventually get. I know I can pick up a used one for 1000-1500 but then I need a new crossmember, driveshaft, and whatever the hell else I need, and the cost just keeps rising. Then I could throw some 4.56 gears and still drive it everyday, lol.

[rtvickers]

WHOA!!! 4.56? Ask Eric about his 4.30's. Do some research on svtp and corral Im sure there's a write up somewhere and keep an eye out for the swap. Might not be as bad as it seems.

Lol u wanna bet a tko600 is out at that rpm range? Get one upgraded from liberty's w carbon fiber syncros an bang away. I spin my tko600 7700 all day smooth shiftin

[dr59l]

BTW w 4.56s an 275/60s I spin 2300@65mph

[4n_eatr]

1. We already talked about the Carbon fiber upgrade. If I can't beat $1500 for a new/rebuilt trans then I'm not doing it.
2. I'm guessing that's a 15" wheel? Even then that's what, a 28" tire? My car is lowered 3" there's no way I can fit those without tucking them, lol.

[cstreu1026]

Personally unless you are getting a viper spec T56 with the really tall over drive you might as well keep the 5 speed because 6th on the Cobra t56 is no taller and the super tall 6th is the only benefit I see to the 6 speed.

The swap is something I want to research and do right. Not just hurry up and get it done. I was looking at the t-56 magnums with the wide ratio gears if I end up going that way. Of course there's always the t-6060 if I ever win the lottery, lol.

[Timido]

I would not spend much more than a couple hundred bucks to repair a t45 to geta car back on the road.

6060 is for the 05 ups. It wouldn't work in your car, you'd need it's cousin the T56. Anyone that rebuilds T56's can do the carbon fiber upgrade to them, you don't need to overpay one of the big names to do it. A used TKO 600 or 500 with a set of carbon fiber rings put in instead of the brass ones will work fine.
The T45 place is owned by some good people, you won't be disappointed. They helped me when I broke something in my race car, we used their trailer and tools to get my car up and swap out the broken stuff. Good people.

Oh ok. I thought they were just an upgrade from the t56. I was going to call you to get a quote for a stock rebuild. When I get the car on the dyno will determine what I get. It's fine for now, I just want to be prepared for if/when it does go out

[rtvickers]

If you had all the money in the world, what trans would you want?

[cstreu1026]

Street strip car....Lenco.

[4n_eatr]

Haha! I've always wanted a Lenco. But if I had to choose I'd like a viper-spec t-56 or a t-56 magnum wide ratio.

[rtvickers]

I guess the motor would have to come into play when choosing a trans. If I went with a TT setup and a built motor and it was mostly a track car Id go glide or TH400 but it would be hard to give up my T56. Because I drive it a lot. If money wasn't an issue what motor would you go with?

[4n_eatr]

Procharged 5.4L.
Right now I'm still waiting to hear back about a job I'm up for so a t-56 might be in my future, but for now I want to get my engine dyno'd (its been almost 10 years since my car put down over 300 rwtq) and see if I'm still close to the 325 lb ft rating. If so I'll get the t45 source built trans, if not I'm just doing a stock rebuild until I can afford a t-56 and an engine rebuild with bigger cams. Theres no way I'm going auto. This car won't be that crazy. It's too rare to make it into a drag car (again). Ill just buy another Fox for that.

[dr59l]

I've got less than $2000 in mine including trans an BTW unless u spinning really hi rpm 4.56s aren't for u especially w a 26" tire. U btr get a set up like the man above my post that Mike did or u will run out of motor before the stripe. If a Guy knows wat he's doing that tko600 will easily meet ur demands an shift hi rpms. Carbon fiber kit w new rail an reshaped billet fingers $400 shipped from amp performance, threaded in front bearing $125 liberty's, shape engagement teeth an cut every other off blocker add mv fluid w friction modifier an a pro5.0 easy hi rpm shifting.

[4n_eatr]

Once I get it rebuilt I'm hoping to be right around 6500-7000. And I'm not really going to change my gears anytime soon, and if I do it might be taller. My point is, weather I'm putting in a t56, TKO 500 or 600, I would still have to change the bell housing, driveshaft/ yoke, crossmember, mess with the wiring, etc. I'm not doing it right now. Just wanted opinions on one company. As of right now, either I'm going with a stock rebuild to get me by, then LATER I will beef up the tranny to a t56, TKO, whatever, or I'm going to get a Built t45 if a stocker won't last me much more than a year.

[Timido]

Street car just repair your t45 or toss in a good used one. Save you money for a real transmission

[9cobra4]

A TKO can and has shifted at 8,000+, I've seen it with my own ears!

My friend has one in his big bore 4v and it shifts at 8000rpm and handles high rpm launches and powershifting quite well. It's been mid 6s in the 1/8 and is holding up.

Happens to the best of us. Lol

[devous1]

Man, I'm glad this thread is here. I tried selling my Kenny Brown again and it was a no go. So I plan to keep the car for a driver and crank it up to 4-500hp. I never thought the tranny would have problems with it. Since it's a 90 5.0 LX I assume it has a T-45? If this tranny can't handle that much power what do you go to? I don't wanna cut the car up or have a shifter that is out of whac with the center console. Educate me, both my cars are autos.

[dr59l]

T45s are behind mod motors. Urs would have a t5. Astro or g. Force t5s will work or just toss a tko600 in like I did an never look back

[devous1]

Damn TKO 600s must be made of gold.

[SN95N/A]

I have a t56 I'm selling not sure if your looking for anything like that.

[4n_eatr]

I am but that will be later when it finally gets boosted. I'll be looking at a Magnum wide ratio so I can have an extra overdrive. I'm just going to do the t45 source for now. A stock rebuild will cost me 800-1000, so for an extra 500 I can get one that will hold around 500 lb-ft of tq that should last me a while.

[Mista Bone]

Any pics of the Carbon Syncs?

I know on the Honda ones I install, we are one the third generation/design.

I will say this, most of the shifting/tranny issues is the drivers timing, but I busted a lot of shifter forks....like the T5/T45/T56's do, same crappy cast alum forks...just without the plastic tips.

Driver Mod :)

The CRX I flat shift. Once I launched the gas pedal stays on the floor until after the finish beams.

The tranny in the CRX has a LSD installed in it 10 years ago, so it is not one of my builds.

While I was racing at National Trails a few weeks ago, one of the other drivers was complaining about issues grinding third gear. We went on a test drive with me driving, full throttle 2-3 shift without lifting and the tranny didn't grind.

I flat explained to him, if you don't learn to shift, you will keep me very busy and well paid to fix your shifting issues.

I duuno what the RWD synchro prices are, but for normal brass replacements it is $150, the carbon lined units are $200.

Remember, a synchro is nothing more than a brake pad, that is it's only job.

How many also replace the spring rings on the RWD trannys? Not really needed on the Honda's unless you break one, but that is a result of something else breaking like a shifter fork.

Driving home from Edgewater with only second gear was NOT fun!

[4n_eatr]

This is what the quote is for:

SureShift Billet Shift Fork (3-4)
SureShift plate 1-2
SureShift plate 3-4
26 Spline Input shaft, heat treated
Billet Steel Hub Inserts (set)
Bronze Shift fork Pads (2 pair)
Bearings
1-2 carbon fiber lined synchro ring
3-4 carbon fiber lined synchro ring
5-R carbon fiber lined synchro ring
Replace seals
Replace stock synchro springs
Replace stock shift fork pad (5-R)
Replace stock synchro inserts (1-2 & 5-R)
Clutch fork pivot ball stud

Can't find pictures of the CF Synchros specifically
