4L60E Trans and Converters

[Dan Fahey]

Can you install a non locking racing converter in place of a locking converter without issue?

There were 4 different turbine shafts available for the 700-R4 and 4L60e . The 4L60e came with 2 of them , a 298mm style , 30 spline , with a short stub journal with a seal on it , on the engine end of the shaft , and a second style meant for the 300 mm converter , 30 spline , but with a larger o-ring seal after the spline closer to the pump . As long as you inform the converter manufacturer which style shaft you have , there should be no problem using a converter without a converter clutch in it .

Been a few years since I delt with this, while my race car was still a street car. Seems like it required an input shaft without the passage through it, or the hole in the shaft plugged. Wish I could remember which. The people at TCI or ATI could tell you.

That 3.06 low gear is not likely a big issue for your car. Mine was like a tractor. Standing straight up, or spinning the tires. Front end stayed up through second gear in good air, if it hooked well. Likely not so much of an issue in a 4000 lb car with less hp. Big RPM drop at the shifts won't help anything. T350 trans was faster.

Concerning the 3.06 first gear, Sonnax offers a replacement 2.84 gear set.

That would be some help.

My car seems to love the 3.08
For K/SA minimum weight is 4057.
Going to be little more than 4100lbs.
Can definitely see benefit of a 2.84 gears for the Camaro/Firebird

I would certainly consider trying it. Although your car is hefty, a lower numerically gear set would provide closer ratios and less RPM drop on the gear changes, and may pick you up some E.T. The 3.06 may provide a quicker 60', for example, but that certainly doesn't guarantee that you will have a quicker E.T. slip. Just my .02.

Hi Jim,
You forgot to mention that deal is 700 bucks.
I can't see the wisdom of spending that money just to bring it close to a stock 200 1st gear. It's never going to as fast anyway. That is, unless there was a real good reason to keep the 700 trans. Such is not the case here.

If it were me, and I already had the o/d trans, I'd probably remove as much of the weight as I could, including the 4th stuff. Then I'd build an 8'', which would be basically, a metric 200 ,with a 30 spline turbine hub.
Then I'd probably figure out what gear ratio that would hang it's tongue out in the quarter. Then I'd back off one ratio, and see what happens.

But, I'm not Dan Fahey.

Dan , you don't seem like a real hands on guy, so here's what I'd do.
Sell the 460 E and the Yanker to one of your buds on the SS forum. Then let me set you up with a 200 / 8 ' combo what would be reasonably priced.
Not looking to get into a bidding war here. Either in or out..What say you?

^^^^^^^^
The 4L60E is not fast! Too many things wrong there.

Mark appreciate the offer.
Right now I am working a lot of hours.
Plus train daily to Ref Soccer games.
Next two weekends Reffing Elite Soccer Tournaments.

In the mean time collecting parts for Stock.
Before adding power better to build safety and reliability.
First a Roll Bar then a Beefed 8.5 rear with Ford Ends.
Those are my next two investments.

As for hands on...when I got time and can borrow a garage I do the work.
Otherwise have a couple close mechanic friends do the work.

I do appreciate your advise.
Will ping you off line.
