Triumph TR6 - T5 gearbox
|I am just about to embark on a gearbox swap to a T5 mustang unit, Does anyone have prior knowledge of such a swap? If so let me know before I put my foot in the water! I cant find an original overdrive for sensible money so the biggest job is making (or finding) an adaptor plate, I am sure that someone must have done this one before.|
|Try the following link for a turn-key 5 speed conversion for the TR6. I purchased this kit two years ago and can vouch for an excellent kit and a good guy named Herman who designed and sells the kit.|
|Thanks for commenting John, I was in the middle of asking for your input when I had to go on to another item of work and I never finished my thought.|
|John . I like the look of It and all the hard work is done, Thanks for your input, I will let you know what I decide to, Many thanks Clive|
|One of the Toyota engineers must (have) own(ed) a TR6.|
Brakes and transmission...what next?
Looks like a nice easy swap. Cost would be interesting to know. OE ODs are scarce and expensive!
There plenty of conversion out there for TR6 and many relies on Jap car like Toyota or DATSUN...
BUT PRICE is usually high.

|I can shed some light on the costs. The cost of the Toyota 5-speed conversion is about the same as converting a non-OD TR6 4-Speed to a JType.|
Toyota Conversion Costs USD as of Feb. 2003
HVDA Transmission Kit $900
clutch Kit $220
Shipping UPS $29.72
Junkyard W58 5-speed gearbox $60
Total about $1,200 USD.
In my case I ran into a little bad luck and blew up the gear box - so add $1200 Canadian for a complete rebuilt 5-speed. Not the norm.
Note the Clutch kit is a slick hydraulic throwout bearing. No more cross shaft and fork troubles.
The Kit includes a clutch friction disk with the correct dimensions to fit the TR6 clutch and an inside spline that fits a Toyota gearbox.
This kit transforms the TR6 clutch into a smooth operating "modern" car feel - not a pussy clutch like found in a Beetle or Audi A4 but something like a mustang or camaro - smooth with medium effort required.
I had trouble deciding on the JType vs the 5-Speed and the future maintenance pushed me toward the modern gearbox as I think 10 years down the road it's going to be dammed difficult to rebuild a JType.
|I have just boaught a Toyota W58 Box from my local yard, The car that it had come from had done 130K miles. I spent $125 on it.|
Just about to place the order with Herman as soon as my tax refund arrives.
|John- Will the Supra box work?|
|Mine was from a supra and herman said that it was the same box just maybee the ratios were different.|
|Any chance the V160 trans will work?|
|You are looking for a "W58" from a Supra. The W58 has the best 5th gear ratio and closest match to the TR6 for the first 4 gears.|
Look for a Serial Number ending with "W58". These are a dime-a-dozen.
Don't use the Toyota 5 speed out of a Truck - the ratios are not what you want.
|I really like the V160|
You won't find a V160 in the boneyard; you'll have to pay big bucks to get it!
|Good summary of the Toyota Boxes|
|John- I figured that. But,Boy Can I Dream. 6 speeds,Rick would be envious. That and those Miata seats!|
Don If your rice burner seats (OUCH:) do not come with the speakers in the head rest, talk to Chris Trace re a much less expensive alternative to OE speakers.
With that many gears you are going to need to add "paddles" to the steering wheel!
|I have an A type OD tranny up for sale. If anyone is wondering why? well I was out to Chris Trace's place for the chili and beer day. Im going to the dark side (V8) ;)|
|Thanks for all your comments and help, Now back to my original question, Has any one done this with a T5 trans? As I have one sat in my garage. The Toyota sounds a great swap ,but my budget does not extend that far! maybe a longer final drive may be a better bet! I have been told that the earlier without the overdrive had a longer final drive 3.55/1 so I am told, can anyone shed any light on this. Clive|
|As Jean stated at the top of this thread. Check out that Dellow Auto. Converse w/them,they might have the stuff you need.|
|Conversion to a J-type OD is not really all that expensive (expensive, but not prohibitive). Keep a watch on Ebay, there is a man from New Zealand that offers a the OD, mainshaft, adapter, solenoid and switches pre-paid shipping for $800-850 US. I bought one from him 2 years ago (it was $650 then, he even included a hollow shifter as used in Stags with the knob switch). He rebuilds them, new gaskets, etc. Installed it, sweet, smooth operation. All you need is to engineer the lock out switch on the shifter rail cover.|
