Talk:Borg-Warner T-56 transmission

Need to include some ratios for Viper and Vette specific tranny's. Maybe an expansion of the differences between the tremec and the BW? Ultrapop1 07:06, Apr 19, 2005 (UTC)

T-56 vs ZF in C4 Corvette
To the unnamed user who keeps editing the first year for the T-56 in the Corvette to 1992, instead of 1997: The T-56 was not installed in the Corvette in any factory configuration until 1997, when it was set up as a transaxle in the 1997 Corvette. It continues to be used in the C6 Corvette and Corvette Z06 today, in the same configuration. Prior to 1989, the C4 Corvette did not have a proper six-speed; it had a '4+3', which was basically a four-speed with an external overdrive unit. In 1989, the C4 received the ZF six-speed transmission - the T-56 was not even available yet, and the ZF / C4 were designed around each other. It would not have made sense for GM to switch transmissions for no real reason in 1992, when the T-56 became available. This can be confirmed here and many other locations - for example, run a search on Car-Part.com for any Corvette between 1989 and 1996, for a transmission, and select the M.T. option - any case where the junkyard lists details, it will often indicate 'ZF'. Please do not edit the page again unless you can find some verifiable proof that the C4 Corvette was ever shipped with a T-56 instead of a ZF 6-speed. Ayocee 16:38, 23 December 2005 (UTC)

at first i was against what Ayocee said about the 92-96 vettes not having a T56. i did research on my own and saw beyound a dout that he is correct. the 92-96 vettes got the ZF ZF6 manual transmission while the F-bodies got the T56 when they were upgraded with the LT1s. the Vettes didn't get this until they got LS1's. i guess what the real question is why did the F-bodies with LT1s got T56s while the vettes got the ZF? Ebay is a good website to varify this. just type in 92-96 corvette manual transmission and all sorts of ZF tranny stuff will pop up. Gulielmi2002 (talk) 18:51, 8 October 2009 (UTC)

Any current applications?
I just did a quick overview of things and it looks like out of the T-56's few remaining applications (more a matter of model death than anything else), most have switched to the TR-6060. Is the T-56 still being produced for use in any new vehicles after the end of the 2007 model year? Ayocee 01:04, 11 August 2007 (UTC)
 * It does look like the the T-56 is being gradually phased out. However, there will still probably be a few vehicles using it after the end of 2007. The Holden Commodore will continue using it into 2008 as far as I'm aware. Since its Pontiac G8 cousin will debut with the TR-6060, Holden may switch over as well eventually but unlikely before late 2008. Likewise, the Ford Falcon continues to use it but there's been no confirmation what the next generation model will use. Also, low volume manufacturer Elfin uses it on the Elfin MS8 Streamliner/Clubman. Since they still persevere with the LS1 V8, the T56 might stay around until the end of time. It might be a good idea to ask your question again next year ;) VectorD 06:22, 11 August 2007 (UTC)

"No internal changes" when moved from BW to Tremec
I've got nothing hard on hand at the moment but I know I've heard that when they moved from BW to Tremec that some minor changes were made - namely synchromesh materials and a few other minor changes. Do we have any verifiable sources that can confirm or deny this? Ayocee (talk) 17:40, 10 March 2008 (UTC)

i do have good experience with this subject. i bought a T56 (BW)that was used behind an LT1. the problem was that i had an LS1 whcih use the Tremec. i was force to change the input shaft, the bell housing, and the adaptor plate. besides the input shafts being different lengths they are the same internally or everything behind the adaptor plate is the same. i have heard that the BW T56 gears were much harder and could stand more torque than the Tremec T56 from virtually everyone on the subject.
