borg warner t5 tranny

I'm Pretty sure I'm gonna go this route. I already have a lakewood bellhousing to go from SBC to t5. I'm going to need to figure out the clutch setup with the adapter plate.

Not that it's a huge selling point, but the T5 has so many configurations, it's hard to know which one you have in case you need to rebuild it. On a side note, the factory T5 is only rated at around 300ft/lbs. Not that most of us will be pushing that, but just take it into consideration.

My step brother also blew out 3rd gear on a mild Chevy 350 just driving down the road. It also bent the counter shaft. I don't trust them, but it doesn't mean it's not a good transmission. Thousands of people swear by them.

the T5 looks like a nice cheap swap if your seriuos

what is the difference in the T5 offered in the datsun 300z?
I know the input shaft changed for the 94 95 mustang, but did it go back to a shorter input after that production run?

after 94&95 im pretty sure they used a t45. only issue about this tranny is that a stock form t5 doesnt shift well at high rpms other than that they are a dime a dozen and have a good amount of aftermarket support. bill if you wanted to make a housing for this unit i have a junk one i can send you for mockup purpose's

a good friend of mine had an '85 IROC budget road racer- he raced it with a 12.5:1 406 smallblock(550-600hp) pushing the BONE STOCK T5 for a whole season before he finally blew it up on the last race trying to max it out on the straight at road america. i think the T5 would be a great alternative to the R154, W58 or T56 for price and quantity. also, they seem to be a lot more compact than the other trannys as well.

what about size in the tunnel? is the Ford thinner than the GM? is there a difference in the world class size?

A WC T-5 would be financially more appealing and realistic to more of us than a W58 or T-56. I have an inside line to WC T-5 Land. One of my best buds works at Mustang Country in SoCal.

I still need an input shaft and a main body for the T 5 trans

Bill if you use Lakewood bell housing part number 15032 its a chevy pattern to ford T-5 it will bolt everything together using your chevy adapter plate, and the pilot bearing will press right into your flywheel adapter (I checked with the measurements you gave me).. Also a little insight on the T-5. It won't shift over 6500-7000 very easily, They are rated to NWC 265 flbs, WC is rated to 300 flbs, the 93 cobra trans is rated to 310 flbs due to the tapered front roller bearings, and the 95 cobra or also referred to "Z" trans due to part Number being 7003-Z is rated to 330 flbs. There is no production T-5 that will handle 500 flbs. The G-Force Dog box is only rated to about that and that is with a beefier T5 case. A lot of problems with these are case flex. The 94-95 trans have a longer input shaft but the v6 or 3.8 trans are the same as the fox T-5. All you have to due is change the input shaft. Hope this helps. I have done all the research into these trans and the swap and talked to bill about probably 2 years ago. This is what I came up with and the combo I found to make it work cheaply. Bills SBC adapter, run a 153 tooth flywheel for a 10.5" clutch, run a 10 spline chevy clutch disc, chevy pressure plate, the Lake wood bell housing 15032 to go from chevy pattern to ford T-5. Press the adapter pilot bearing into bills flywheel adapter and bolt your T-5 up.. Good to go. I even modded my setup and bell housing to use the mustang stock clutch setup.. LMK if you guys have anymore questions. Thanks

would the Chevy flywheel be balanced for the 4G63?
I would have to remake the coupler to hold the manual trans flywheel

Djchunter · Post by **Djchunter** » Sun Feb 08, 2009 2:14 pm

Chevy flywheel is a neutral internal balance so it should be fine.. And your current coupler should be fine. Why would you have to remake the coupler?? The Flywheel bolts up the same and is interchangable chevy to chevy, should all be the same. Also the pilot bearing should sit inside your step for the tq converter snout.

there is no stress on the torque convertor locaters in the auto trans set up, once the convertor is located in place the outer convertor bolts connect the convertor directly to the flywheel, the input shaft on the manual trans needs a strong enough pilot bearing to be held in place when the clutch is depressed.

I'm sticking with my story. The T5 just isn't up to the abuse most people put it through. The reason there is so much aftermarket support is people trash them and both Chevy and Ford put them in everything.

As Djchunter explained, the transmissions are not rated well from the factory. Maybe they are stronger than their ratings, but a trans listed at 300ft/lbs won't hold up to an EVO3 16G power shifting at 7500rpm.

If you were using aftermarket transmissions like the TKO or Richmond versions, then I would go for it. I think it might be a viable option if you can bolt it to Bill's GM plate. Especially over using the MM KM132. I don't want to discourage anyone, but look at all the angles before you decide to put down your hard earned money.

If you have to buy all the aftermarket parts to allow the T-5 to stand up to what the other transmissions are standing up to-- then why bother???

HP is not the issue how many 302's do you know of that spin to 9K bottom line is this trans will not like to shift.

WC was only rated to 300hp the "Z" trans came in the cobra's. All T-5's were WC's after 85.

Agreed. Bill keep doing what you are doing. I think the 3 options you offer for manual transmissions are plenty.
