Already posted this on LS1Tech but figured some of you guys right know. I may have an opportunity to buy these and I’m wondering what they’re out of, and what they’re worth. I have no clue what these are from, but they look to be from Corvettes. I don’t know if they’re C5/C6 application, or maybe something else. Total of 3 transmissions. #1. ![http://farm9.staticflickr.com/8065/8205944017_9057a565b6_b.jpg](http://farm9.staticflickr.com/8065/8205944017_9057a565b6_b.jpg) ![http://farm9.staticflickr.com/8485/8207034540_89b28bf599_b.jpg](http://farm9.staticflickr.com/8485/8207034540_89b28bf599_b.jpg) ![http://farm9.staticflickr.com/8204/8207032646_0bf1ef6c2e_b.jpg](http://farm9.staticflickr.com/8204/8207032646_0bf1ef6c2e_b.jpg) ![http://farm9.staticflickr.com/8349/8205940983_e5df7ba2b9_b.jpg](http://farm9.staticflickr.com/8349/8205940983_e5df7ba2b9_b.jpg) Looks to be a Tremec TR6060, according to the TUET6613. #2 ![http://farm9.staticflickr.com/8059/8205943515_5bea891981_b.jpg](http://farm9.staticflickr.com/8059/8205943515_5bea891981_b.jpg) ![http://farm9.staticflickr.com/8341/8207032106_51dc4a233f_b.jpg](http://farm9.staticflickr.com/8341/8207032106_51dc4a233f_b.jpg) #3 ![http://farm9.staticflickr.com/8200/8205943131_28f8175b96_b.jpg](http://farm9.staticflickr.com/8200/8205943131_28f8175b96_b.jpg) Case Casting Number off of one of them, don’t remember which What vehicles/applications are these out of? ---

You can probably use the design of the tailshaft to figure out what they go to. ---

Like I said they look to be from Corvettes, but I’m not sure if C5/C6, or what. I have literally no information on them. ---

> [@96V6Bird](#): > > Like I said they look to be from Corvettes, but I’m not sure if C5/C6, or what. I have literally no information on them. They are all from Corvettes. Why are you looking at a C5 or C6 transmission for a RWD car? If you are looking for a transmission to use that still has the triple cone synchros you would be better off with a GTO transmission or Chevy SSR (but there wasn’t many made) ---

i do not want to convert this for my car. I just have the opportunity to buy them cheap and use them as credit towards rebuilding a RWD style T56 through a rebuilder. ---

because i don’t feel like spending thousands and thousands to “skip all the trouble”… so, here’s the trans i’m looking at. before i drive all the way down there i’d like to make sure it’s LS1 application. i don’t think the case casting number can tell me the origin (1386-065-902). i have the seller working on getting me pictures of the sticker and the metal tag under the bolt on the rear extension housing. in the meantime, can anyone here with a trained eye tell me if this is LS1 application T56, and how can they tell? maybe the bellhousing? i’m not a GM guy but the trans crossmember looks LS1 application. ![http://farm9.staticflickr.com/8504/8274121901_a7f82631d9_c.jpg](http://farm9.staticflickr.com/8504/8274121901_a7f82631d9_c.jpg) ![http://farm9.staticflickr.com/8203/8274121825_48547e787e_c.jpg](http://farm9.staticflickr.com/8203/8274121825_48547e787e_c.jpg) ![http://farm9.staticflickr.com/8342/8275184190_3ff078162b_c.jpg](http://farm9.staticflickr.com/8342/8275184190_3ff078162b_c.jpg) ![http://farm9.staticflickr.com/8353/8274122087_a00d1c0d9d_c.jpg](http://farm9.staticflickr.com/8353/8274122087_a00d1c0d9d_c.jpg) ![http://farm9.staticflickr.com/8501/8274122209_43734681db_c.jpg](http://farm9.staticflickr.com/8501/8274122209_43734681db_c.jpg)
