5 speed trans applications


Recommended Posts

is the beretta gt 5 speed the same one as the cutlass and the grand prix had, minus the axles?

I just wonder where everyone gets there 5 speeds from, since the cuttlas only had one for a very short time? thanks!

different bellhousing, if i remember right, and different gear ratios. Get a w-body tranny if ya can

Posted

Plus I think it'd be the Isuzu trans, which is much weaker than the Getrag.

i seem to remember the beretta could be had with a 282. the differences were the gear ratios and input shaft if i remember correctly. bellhousing should be the same :shrug:

Posted

The bellhousings are the same from every 60* V6. The axles, input shafts, tranny mounts, and gearing are different.

input shaft is different? i thought the ONLY difference was the FDR and gearing?

 

and yes the V6/5-speed Berettas got the Getrag HM-282. the Isuzu 282 was mated to 4-cylinder engines, besides the Turbo 2.0 and HO Quad-4 which also got the Getrag 282 (different bellhousing of course).

i've seen a beretta 3.1/5 speed. the input shaft LOOKS way different from the w-body. might just be the housing, but i believe the lengths are different, too

just did a search on dialaclutch.com

 

'89 Beretta with 2.8/5-speed and an '89 Grand Prix with 2.8/5-speed share the same clutch (same part #) and both have 14 spline input shaft.

damn it, i don't mean the input shaft. i mean the one that comes from near the bellhousing to the pass side and mounts to the engine

oh that's the intermediate shaft - basically a solid axle. yeah i'm betting that is different. i have actually seen L-bodies in the j/y with different types of intermediate shafts when i was looking for my intermediate shaft bracket. one 2.8/5-speed Beretta had an intermediate shaft with an integrated bracket, but then i found another 2.8/5-speed Beretta that had an intermediate shaft and bracket just like a W-body (still probably different length...but it did "look" about the same). i am using the intermediate shaft bracket from that Beretta on my Cutlass right now.

Posted

that's what i meant. for some reason input kept popping into my head.

 

but yeah, ask over on beretta.net or something. i'm 99% sure the intermediate shaft is shorter for rettas and cavis

Posted

i figured the drive axles would be different, but the main body of it would work. The w body 5 speed is getting hard to find.

so the FDR is the same as W 282. i would actually prefer the J/L 282 over my W 282. 1st and 2nd gear isn't so freaking steep, and more overdrive in 5th.

Posted

really? i can get you one from a beretta gt 3.1 for 250.

 

at least that what i was quoted when i asked about it last year

Funny part about that, I've often messed with the idea of using a W 282 in my 3400 Beretta.......but you make a bit more power than me. ;)

yeah, even 2nd gear is spinning the tires under full boost. 3rd gear is fine. a 282 with less steep 1st and 2nd gear would be really nice, but then again maybe i should just think of getting a bigger turbo with more lag ie. traction control :lol:
