Re: HELP! OD prob tracked down, but I need advice
It's not, not flipping the switch in 3rd that's the problem as much as remembering to flip back before leaving 4th. But I guess the jump from OD4 to 3 would be nearly as annoying as OD3 to 2nd. Though perhaps not nearly so much as OD2 to 1st. That must be a bit of a shock.

The 16v Slant 4 engine is more fun than the 3.5 V8, because you mostly drive it on the upslope of the torque curve.

Re: HELP! OD prob tracked down, but I need advice
This is just my laziness speaking up here....
I see where Robsport sell a small wiring loom for Stags gearbox and overdrive.
https://robsport.co.uk/index.php/online ... on-gearbox
And the gear lever switch downwards is easily available too.
https://www.ebay.co.uk/itm/Triumph-STAG ... SwYHxWKh74
But, do any of the vendors make or sell a wiring loom for the Sprints gearbox and overdrive?
I emailed Simon at Robsport and got a NO from them.

Re: HELP! OD prob tracked down, but I need advice
I really like it on 3rd. On an incline I like to hold 3rd then o/d it and if I start slowing just flick out and Im good to keep pulling. Its a bit odd when you forget its in o/d and shift from the 3rd to 4th and you get the slight delay though

The plastic multi pin connector is different to my car, but is easily modified.
I'll order one ASAP.
Thanks & Cheers,

Re: HELP! OD prob tracked down, but I need advice
It doesn’t appear to include the bit that goes up the stick to the switch; the terminals there have to be very small in order to fit within the knob...Sundowner wrote: ↑Wed Jun 19, 2019 4:20 amYes its is Bish.Bish wrote: ↑Wed Jun 19, 2019 2:54 am Is this any good?

For those who need reminding when overdrive is on!!
I had to resort to the large warning light - 18W amber on the right side of the dash. The red was 18W oil pressure warning. Worked but I'm sure a smaller version would be fine in a road car.

Those terminals on the overdrive switch are small - i used 2.8mm spade terminals + some 1mm cable to renew mine.xvivalve wrote: ↑Wed Jun 19, 2019 7:59 amIt doesn’t appear to include the bit that goes up the stick to the switch; the terminals there have to be very small in order to fit within the knob...Sundowner wrote: ↑Wed Jun 19, 2019 4:20 amYes its is Bish.Bish wrote: ↑Wed Jun 19, 2019 2:54 am Is this any good?

Re: HELP! OD prob tracked down, but I need advice
I don't get that, it seems to stay in OD on the change.
I specifically checked this recently on the Herald, and that spitfire IV box (I think - reverse is up and left) stays in OD while in neutral, as long as the stick is over to the right hand side - I can hear the solonid operating with OD selected and moving the gear stick left-right in neutral. That used to have OD in all gears, including reverse. But it's better now.
I have yet to do that test with the Doly cos the mechanic who fitted the speedo cable disabled the OD - I assume he broke a wire. I intend to take the tunnel up and look at that asap.

Re: HELP! OD prob tracked down, but I need advice
Its like the inhibitor switch momentarily disconnects then re-connects when the selector moves to 4th on mine.
