Triumph TR6 - Gearbox
|I was thinking of having my gearbox and overdrive rebuilt during the winter and I started to remember a conversation I had with a six owner at a show. He mentioned that he had swaped his box for a modern 5 speed one, I think it was a Mazda not sure. He reconed that the drive and acceleration was much better and smoother. Has anyone done this or heard of this being done. I would like to know more both good and bad.|
What he was probably describing was a W5 Toyota transmission that's a virtual drop in to our Tr-6's (I'm told...haven't done it myself yet!). Check the archives here and and the web and you'll find several detailed articles for the swap. If you combine the Toyota 5 speed with a Missan differential, you don't have to shorten the drive shaft. Otherwise the driveshaft has to be shortened about 2 inches to make it work. There are houses that will do the conversion for you. I think Richard Good does one.
|There is a new conversion out that uses the T5 trans and it is cheaper ,I think|
|I think, on reflection, that the Toyota transmission is the W58 model found on a number of Toyota vehicles in the 80s/90s.|
|Malcolm, I put in the Herman Van Den Akker Toyota 5 speed kit 3 years ago this winter and I am very satisfied with the kit. One time when talking to Herman about something I asked him how many kits he had sold, he said it was around 300 at the time. He was also sending I think it was 5 kits to the UK that winter, so there are some over there. Don is also right in that there is now another person making kits for the Ford T5 tranny. There also is/was someone in New Zealand I think making a T5 kit. I vaguely remember a kit using the T5 from the UK as well, but I could wrong about that. The HVDA kit is by far the most popular on this side of the pond with literally hundreds of happy users. Price is comparable to rebuilding the stock trans without the complications of the OD. NFI.|
|Think The T5 is a GM|
|The T5 is a Borg-Warner unit. Ford started using them in the early mid 80's in their Mustangs. I think in the mid 90's B-W started making what they called their World Class T5, apparently it is a stronger unit, will take more power than we could possibly make. Gm and others may also have used them, I don't know. I just know Ford did. There should be a gaggle of them in wrecking yards everywhere. |
|The trans I'm thinking of is a 5 speed from a Gm I think|
