Manual Transmission Selection.

[trevor572]

Hi. I am fitting a gm performance 572 crate engine rated at 650 ft lbs of torque into a 1st gen camaro , I would prefer a 4 or 5 speed manual trans, I am probably too old fashioned, a 6 speed just seems too modern or hi tech for me, any suggestions or recommendations guys? Cheers trevor.

I would into a Jerico or a Legend tranny with that amount of Torque if you only want a 4 or 5 Speed.

Thanks, i found a dealer for Jerico out here today and have contacted them, also have been looking at legend online. Thanks for your advice. Cheers.

I am a Legend distributor and I can answer your questions.

[trevor572]

Hi Josh, yeah I saw you listed on legends website, I will do a little research, make a decision and probably give you a call, so sharpen your pencil mate. cheers, trevor

I would drive a Jerico on the street for a few days before buying one. Dog boxes have their place but I in my world the street is one of them. Lots of TKO600s survive behind 600+'/#s but it's at the upper end of the transmissions design space.

We have our direct fit 5 speed Tremec 1st gen Camaro TKO kit for your car. Feel free to give me call and I'll be happy to help you.

Hi Wendell. I was speaking to a dealer for Jerico and a number of other transmission manufacturers and he echoed what you said exactly, as much I didn't like the idea of a 6 speed in the old girl, in his opinion a T56 magnum was by far the best option. Thanks for your advice. Cheers trevor

I run a t56 and it's great. It's a quiet, but you'll forget about that when your shifting at 7000 RPM without issue. And if you want the old school noise different gear cuts are available.

[trevor572]

Hi Bovey. Lack of gear noise won't worry me in the slightest, as you mentioned it's all about the engine. I have been looking at the hole in the dash for years thinking I should put a radio in that, nah!!! just bought a block off plate instead. ☺ love your ute btw. Cheers.

I think your choice of a Tremec is the winner a 5 speed in these cars are the way to go.....this year my own car will be changed to a 5 or 6 speed....I will say its tough when you have the right rear-end ratio for autocross with a 4 speed the RPMs on the freeway at 70 mph are buzzing at 3000 and it really sucks driving at 75 mph like in Texas for hours at a time

Not to mention that leisurely drive through Texas would be punctuated with stops at the gas station mate.

Sadly, I have seen a few broken TKO's when fitted behind a 572 and 3rd gear was the failure.

[JodysTransmissions]

Here is some food for thought when setting up an OD driveline with a 572/620 or any BBC with square port heads. The 572 likes to breath at 3200-3300 RPM around here, it is not fun downshifting constantly if you try to gear them at 70MPH at 2000RPM.

Whatever transmission you buy, make sure it will compliment the engine and differential gearing or you will be very unhappy.

[trevor572]

Hi Jody. I will be going to a T56 magnum, you raise a valid point about rear end ratio, I will be certain to research everything carefully. Cheers

Just catching up. Noticed your going t-56. You will not regret it. As others have said, put some thought into the street or road race version. I originally did the street version with a .50 6th. It's tricky to use behind my 427 LSX. It's great above 75 mph, awesome at 80-90 mph. The road race version is still a double overdrive with a .63 6th. I'm currently researching if I want a stock one or a modified on for my use as my rpm drop on track days is starting to annoy me. If you really want to go crazy, a company out of Texas does Sequential t-56 conversions... wait for it.... for $21000....

[trevor572]

Hi Bovey, Yeah nice 21, 000 dollars, have to lose a zero to interest me mate, I am by my own admission, CHEAP !!!.�� Cheers mate.
