Manual Transmission options
« on: November 24, 2019, 12:32:45 PM »
I have an lt1 style t56. If I was to eventually go ls then would it be more cost effective to pick up a ls t56 or swap out parts on the lt1 t56?

 I've also been reading up on the RS5R30A out of the z32 300zx. They seem to be fairly stout and cheap unlike t56's, r154's, and recently cd009's. Can anyone weigh in?

A quick google yielded this article, which references a conversion kit for $398:
http://www.superchevy.com/how-to/ghtp-1203-lt1-t56-adaption-new-version-conversion

There's no option that's gonna be cheaper than that if you have the tools/skill to install it. It would probably still be cheaper to take it to a transmission shop and ask them to install it than sourcing another transmission.

Other than that, my estimation is that if you have the skill to make one-off mounts and source a driveshaft, the CD009 is going to be the future budget option but since I haven't seen anyone do it in a swapped RX-7 yet, there might be something stopping it from happening.

Given what T56 prices are doing, I think I'd just buy a magnum at this point if I was really starting from scratch.

The benefit of the CD009 is that its fairly common/available and its pretty stout. Shifts WAY better than a T56 as well. However, its a 1 piece design, so there's no bell housing adapters or anything like that which are easy. Sometimes you see people literally cutting off the bell housing to make adapters but that does not make it a very repeatable deal.

CD009 is a waste of time and money behind a V8. You will NEED to do an 8.8 conversion and run a 2.73 final drive to make it a viable option. You’ll end up paying more to run a CD009 in the end, unless you come up on some very good deals for the 8.8 conversion and the install kit.

I don't like options that require special conversion clutches, throw out bearings, pilot bearings, etc.   Those are a pain in the ass if the company goes under.   And you typically don't save that much money.

I bought a TR6060 for my Mustang, with 13k miles, and a twin disc clutch worth 1400 dollars for 2200 shipped.   I bought a T56 that needed a new shift fork for 1100 and fixed it (and upgraded it internally) for another 230 dollars.    It's not that hard to do one for a reasonable price.

Z32 trans is not ideal because you have to put the starter on the bell housing, really terrible for packaging.

Is this just because the CD009 gear ratios are wrong/suboptimal?

The CD009 ratios are considerably shorter than the 13B 5 speed. It's 5th gear is 1:1. With 4.1:1 rear gears, a 25" tire, and 6500rpm redline, you'd be shifting into 6th  at 118mph.

To have similar gearing to a "close ratio" Magnum and stock 4.1 rear gears, the CD009 would need 3.08 gears.

CD009 is a major pain in the arse to make work properly..... '93-02 T56 is not the smoothest shifting transmission... and is also 20+ YEARS OLD.  look in the vendors section for NorCal motorsport under the T56 magnum for more data.

Do some research and don't buy a truly conversion nightmare... The driveline is one of the most important parts .... and definitely not cheap if you want it to last.

And keep in mind the 4.10 stock rear gear with an LS is borderline too short as is. You’d need an 8.8 conversion with a 2.73 rear gear and it would be about identical to a t56 or Magnum F with 3.73 rear gears.

Unless you can find a deal on a Fbody t56 which are few and far between, pick up a Magnum F from Mark, you’ll be time and money ahead.

Of note.... the 1993 T56 is 2.97 ratio and cannot be converted from LT1 to LS style... only the '94-97 units can be converted (2.66 ratio).  Also being 25+ years old it is highly likely that it will need a rebuild once torn down unless you positively know it has zero issues.  A '94-02 style T56 will never shift as nice as the new T56 Magnum (which is a TR6060 in a universal case basically).  The stock internals of a T56 Magnum have also been low 7's@205mph behind a turbo Supra drag car (the synchros were machined off and dogs welded on for no lift flat up shifting as only real modification).... plenty of them running 8's in 100% stock from.

Some food for thought, with the Ronin 8.8 kit & explorer donor parts it is becoming affordable to 8.8 swap vs 10 years ago. Those with an LS swap are always one hard wheel hop from wrecking the oem diff. IMO saying you have to 8.8 swap to use X transmission should be moot. When picking a transmission since you should be gearing the car appropriately anyway for your tire, a 4.10 rear with an LS swap has always been impossible to use 1st gear on the street with any real throttle. I personally choose the cd009 in this other car I am putting together because I want it to feel like a Japanese car through the shifter. In a few years when the tr6060 f-magnums start popping up used for mid 2s i'd consider switching.
