Knob questions...

No, this isnt a thread about the painful rash I have, but about gearknobs. I currently have a Veilside one fitted to the car (6 speed) which Im looking to get rid of, as it looks past its best. Was searching for the thread size required on here when I noticed people talking about lift-up reverse on their 6 speeds. My 6 speed doesnt have lift up reverse... WHY?

I would say its broken. The reason for the lift up is to stop you from going into reverse when aiming for first. All 6spd shifts are like this. A lot of 5 speeds have the lift too, for safety.

 

Just be careful

 

Hmmm, Im worried now. Car is still under warranty from the garage (4 hours away), wonder if its worth getting checked out? Anyone else had this issue?

Hi Dave, is the reverse position to the right and backwards of the 6th gear? Only the 5spd doesn't have the lift collar for selecting reverse (its about in the same position as the 6spd reverse in terms of feel).

 

Yeah, think it is right and backwards from 6th gear, which means Im in danger of going from 5th to reverse I guess.

You won't be able to go from 5th gear to reverse anyway, the box will give massive crunching noise (you'll feel it before you hear it), there's no way you'd be able to engage it, it's impossible even with the clutch down as there is obviously no syncro between the gears.

 

Still a bit odd that thats there's no collar on the shifter though. The 6spd NA's I've driven (Facelift SZ-R's) have all had them, same as the TT.

 

Does it have a short shifter fitted?

There is a collar, it just doesnt do anything- sits down inside the leather(ette) gaiter, and rattles a little bit at speed. How do I always manage to find cars with some crazy unique problem?! This couldnt be doing any damage to the box could it? I cant afford the £100k or however much the Getrag goes for these days!

The shifter sounds like it's knackered then (and possibly a worn out aftermarket one, been there!)

 

They are not too expensive to replace if it's faulty, just a PITA to do.

 

Just remember the pic below when going to 6th, it's not directly behind 5th (the line for 6th is not an error, it's slightly offset)

Is this something that could be replaced with an aftermarket 'quick-shift'? (Dont even know if these are available for the Getrag box?) If I need a new one, it might as well be uprated. How much of a PITA is it really? I know it easy on some cars...

Quick shift are a nightmare on the 6spd, unless it's a very low mileage car. I'd specifically warn against going for one of those, it'll only make the problem worse.

 

Get it checked out by a mechanic thats experienced with these cars and then, if required, the shifter fixed or replaced. Not sure who to recommend in your location, but tDR might be able to recommend someone as he's up your way (and knows a thing or two about these cars). Send him a PM, he'll be able to advise if he doesn't see this thread.

Hi Dave,

 

Sounds a bit odd this one. Is there perhaps a mechanism in the Veilside shift knob that permanently engages the safety lockout? Perhaps another six speed owner could try lifting the reverse collar and going into a forward gear to see if this would be a possible explanation.

 

I'm tempted to say if it ain't broke, don't fix it. Does it give you any trouble / strange noises when you do go for reverse? If not then why worry...

 

As for people to look after these cars in this neck of the woods, it's pretty scarce to be honest. For simple non Supra specific stuff like general servicing use a garage you know you can trust already and for the specific stuff the only place that springs to mind is Hypertech in Bonnybridge near Falkirk. They seem to have a decent enough reputation and have worked on Supras as well as other Japanese performance stuff.

 

Cheers,

 

Brian.

DAT Inter- glad to see you have so much faith in my mechanical knowledge! ;) Yes, its most definitely a 6-speed, as indicated on the VIN plate (and the sixth gear!).

tDR, Ive been meaning to take the car through to Hypertech for a couple of weeks anyway, as I want to get a quote for fitting afew bits and giving the car a service, so Ill get them to have a look. The gearbox is totally problem-free, noisy and agricultural as everyone always says, but otherwise perfect. It slots into reverse smoothly with no noise whatsoever, so unless Hypertech spot any further issues Ill just leave well alone.

Im guessing maybe an aftermarket short-shift is fitted, as Homer said.

Just another quick query regarding the V161- how interchangeable are the boxes on mkivs, and how much do V160/V161s go for used these days? (I know theyre a fortune from Mr. T, and Ive seen used ones on here for around £2k)
