:?: I know I'm being a little parinoid, but, since I'm getting a new crate motor, but the tranny has over 100k on it, I'm sure at the most inoppertune time it will go to. question: If I were to replace the tranny, could and/or should I go w/ the HD version that comes in the SC'*. From Will'* tech info it seems that it should fit, but is there subtle things ie computer issues to consider. Price wise there is like a 100 bucks difference between the two. Well to be technical there are 3 choices. The NA have two trannies that look the same and have the same specs, but different tag #'*, but that'* a whole nother question. Just trying to prepare for the inevitable! :?:

Why not just get the one you have rebuilt? In Canada, it cost me $1800 for a complete rebuild. That way, you are assured that you will not have any problems involving the switching of trannies. Just my opinion.

Get an HD version, it will bolt right up to your car with no problems. And the only obvious difference would be the final drive ratio (all Series I L67'* we're 2.97 I believe). If there is necessary change in electronics, its news to me.

I know I'm planning on getting the HD if and when mine blows....which shouldn't take long with nitrous.

The gear ratio will screw with the PCM. Your shifts will all be at the wrong RPM'*.

Will, would a chip change correct that, or is it pretty much a done deal?(the rpm shifts)
If I put in a aftermarket chip.

You would have to have a custom burn. Is it worth 3-500 to you?

You can't use an SSEi chip to get that gear ratio, as the SC stuff is in the PCM. And no other cars without a SC were offered with the 2.97 ratio in 94.

So if you want to go to the HD, you'd have to custom burn a PCM, assuming you could find someone that would do it, and knew how. There'* alot of risk in this.

Not really worth the risks. The other question is, there were 2 trannies listed for the 94sse, both identical except for tag #'*. Does that mean anything, or are they essentially the same? all the specs, and prices were same, just diff tag #'*? :?:

Not sure on the tags. It might be a different gear ratio. As far as Allmachtige'* comments above, he may indeed go with the HD version, as the shift points may benefit his mods. I'm not tranny expert, but my belief is that his shifts will be at a higher rpm than the trans is normally shifted at, but that will benefit him as his torque and hp curvers are different than yours now.

Mach runs at the track regularly.

Cool thanx! I'll try to reserch the tags and see what'* up. I'm curious now!

BTW I want to trick out my Bonny some, but I will prolly never do the track thing or go for the extreme stuff. So I don't need over kill, but I just want to get the best bang for my buck. I don't want to pay big dollars for something then find out later for a little more I could have had bigger and/or better. lol Ain't that the way it is?
