Z34 tranny swap

[goatman]

Are there any extreme firewall mods to swap a Getrag 282 or 284 into a Lumina Z34? (By extreme I mean like intense cutting, hammering, shaping, and other shit like that there) Also, which trans would be better for my application?

[goatman]

Actually, I was reading through an older post about building up the automatic. What all can be done to that? Is the 4T65-E any better than the 60-E? What about torque converters, anything about one better than the other? Sorry for all the Q's, but nothing better to do right now.

The 5 speed swap has been done by a few people, including myself. FOr the firewall, you gotta pull a plate out of it and swap it with the 5 speed....or you can modify the hole for the clutch hydraulic mount. It wouldn't be quite right but you can make it work. Other than that, hole saw is about all you need and the clutch pedal. Its not a simple or fast swap but worth it IMO, especially if you like a manual trans. You would want the 284 for the better gearing and higher torque capacity. 282 can be built up and you can swap gears out to get close ratio with it as well so thats really up to you.

From what I've been reading, it sounds like the 284 is kind of tough to find. If I can only find a 282, where can I find the parts and info needed to make it the best that it can be for my car?

a 4t65e can't be swapped in with out major computer work.. there is a lot of aftermarket availible to build up a 4t60e though.. your lumin being a 93 might not be a 4t60e, I am pretty sure it's still just a 4t60(non electronic version)

[goatman]

No, it is the the 4T60-E, that is what it says on the pan, anyway.

'93 Luminas have a 4T60-e...your pan isn't lying to you.

I was pretty sure it was the 4T60-E, wouldn't the 4T60 have the kick down cable from the throttle?

no... the 4t60e has computer controld soliniods to control shifting.. this replaces the kick down cable..

[goatman]

Right, I meant that the 4T60, the non-electronic, would have a kick down cable

ZZP sells a built 4t60e for the same price that they sell there built 4t65eHD.

Just some info for you.

*ALL* Z-34's got the 4T60-E (440T4-E) from 91 thru 94.

Building up a 4T60-E is fairly easy tho, you don't have to be a master mechanic to make one work - but you do have to be mechanically inclined to do the job.
