Jim Bowen 1 Posted July 10, 2014 Have the original gearbox that came with my corrado and a spare that i bought with an engine from here, although it was in a golf it was a corrado engine, so i'm not sure what gearbox i'm running at the moment. Is an advert on ebay for rebuilt VR6 gearboxes at £495 on exchange. Do i need to make sure i get a certain code of gearbox? Been reading online and saw a CCM with a 3.68 gear from a G60? Its on VR6OC. Am going to check what's written on my two boxes tonight, but what would be the best option and how do i make sure somewhere that rebuilds my box does it to correct spec rather than just golf vr6 box. Am still a bit confused on all the different codes. Quote Share this post Link to post Share on other sites
Jon_vr6 1 Posted July 10, 2014 Think VR6 manual gearboxes are O2A Quote Share this post Link to post Share on other sites
dragon green 4 Posted July 10, 2014 http://wiki.the-corrado.net/02a_manual_gearbox_general_information_ratios_codes_etc.html I'm sure you've seen this before,but worth checking out again Quote Share this post Link to post Share on other sites
Jim Bowen 1 Posted July 10, 2014 Hadn't looked at that guide, not sure if its helped or not, been doing some googling and did find quite a few threads on here pop up discussing what gearboxes had what ratios and final drives, but i'm still unsure, was some people saying the corrado vr box is different to the golf one and some saying different years of corrado had different ratios. Will see what two i have and ideally just get my original rebuilt, i just know they are on exchange basis and didn't want to get a lesser box back (if it makes much difference) i won't be getting it from VW dealers just some gearbox specialist that probably won't really know about the corrado quirks and confusions.

Am still a bit confused on all the different codes. Your Corrado VR6 box will be CHN, the Golf VR6 box is CCM. Both are identical internally and have a 3.3 final drive. Gearboxes from a VR6 and a G60 are from the same "series", 02A, but a G60 will not fit the VR6 as the casing has a different bolt pattern where it meets the engine. This is mainly due to the angle of the engine as the 4 cylinder and 6 cylinder have a different alignment in the bay. The box on VR6OC has been rebuild with a 3.68 final drive from a G60 box which gives better acceleration but decreased top speed. Quote Share this post Link to post Share on other sites

All UK VR6 Corrados will be CHN and have a 3.389 final drive as standard. Corrados in the US will have a 3.647 FD to make up for the fact they only got the 2.8 engine. You could get a 3.647 crown and pinion fitted when you get yours rebuilt or even a 3.944 for better acceleration and fun. :D Edited July 10, 2014 by science Quote Share this post Link to post Share on other sites
