Hi

My project V8S is missing most/all the gearbox selector bushes. Changing gear is a nightmare.

I'm booked in to Lloyds Specialist Developments to have them changed (£140 + VAT!) but its not until August and I'd like some stress free gear changes before then, so I'm considering tackling this myself.

Have any of you good souls replaced the bushes on your gearbox? Is it a can of worms? It feels like it should be doable in a single weekend, but is it? Or should I just put up with it until Lloyds can fix it in August (there are other jobs to do)???

Any sensible advice from gratefully received.

Cheers

Ian

Hi

I changed the bushes which I think you're referring to. I may have misunderstood but I replaced the bushes that fit between the gear selector plate and the vertical lugs on the gearbox housing. Is this what you are doing?

I did it by taking skin off knuckles and back of my hand using sense of feel mostly as I couldn't see easily, from the top after removing gear stick gater.

It was a while ago but I remember the hard bit for me was fitting the bush between the two lugs, lining up and threading the bolt through and then feeling to fit the nut on the other side without dropping them below.

I was made possible/easier using adjustable angle ratchet spanners

But it was doable.

It can be done. See HERE

But TBH is Lloyd's reckon they can do the job in two hours and that's a fixed price hold them to it.thumbup

That's an interesting post, v8s4me! I'm not sure I'm ready to start cutting fiberglass out of the transmission tunnel just yet. Sticking epoxy in the stone chips on the front bumper are my limit with that particular skill.

I suspect I'll take a look, skim my knuckles as per gizzardio, and still end up at Lloyds...

I'll post some photos when I attempt it rotate

Cheers

Ian

Finally got fed up with the gear shift. And my slot at Lloyds is still 3 weeks away...

Have taken the rubber gator off to expose the top of the gearbox. Here is a small video of the whole selector moving:

https://photos.app.goo.gl/aGm5c6j7VnBjwhmD6

I see four bolts that go through the selector and into the casing. Each bolt is secure, but the selector has significant movement around these four bolts - there are two bolts at the top-front, and two at the bottom on either side towards the back. Will this movement really be cured by undoing the four bolts and inserting the F0038 gear linkage bushes from
https://www.racetechdirect.co.uk/car-parts/transmi...
or
https://partsfortvrs.com/tvr-parts/part-details/tv...

Surely there should be some rubber in there as well?

I'm confused and slightly out my depth confused

Any help gratefully received,

Cheers

Ian

I can't believe that's even drivable. Has someone removed and refitted the 'box in the past? If the correct length bolts are used then the combination of the spacers and the rubber bushes will take up all the movement. The rubber bushes are also available from Rimmers.

Hi Philpott and v8s4me

Many thanks for the help - bushes ordered, new gator ordered (the old one was already shredded before I removed it)

The car is "mostly" drivable. I did have to abort an overtake this morning when I couldn't select a gear yikes so it is parked up until it is fixed. No word in the car's history about gearbox work, but the gearstick has a dogs leg in it, rather than the straight sticks you see on Racing Green etc https://partsfortvrs.com/src/uploads/parts/PTVR%20...

Cheers

That's not remotely straight, it's just photographed with the front towards the camera.

The gear lever is a rover one that's been chopped off about three inches from the bottom, a bit of flat bar welded to it to bring it forward and then the top few inches welded back onto that. Typical TVR really, entirely lacking in subtlety but reasonably effective.

Some "clever" photography on the parts websites laugh

This is how mine looks:




I'm guessing that is a standard TVR gear lever.

Well it's definitely not the work of British Leyland laugh

Maybe someone has been mucking about with that.

Work is progressing, so I thought I'd share some photos!

Here we can see one of the bolts that needs to come out. There are 4, and they have 13mm heads...




I dowsed all four bolts in WD40, then removed them. Fortunately nothing was seized, so it took sub 10mins! The selector needed a 90degree twist to lift out of the hole in the transmission tunnel. Here we can see the void where the selector sat, and you can see the drive shaft, the gearbox selector shaft, and the fuel line. At the top are the two bolt holes, and just above the drive shaft are the two remaining bolt holes:



Once out, I cleaned up the selector with some Morgan Blue degreaser. The ball and cup will be regreased once the new bushes arrive


Cheers

Ian

I think you'll notice a huge difference in the gear change one you have all that back together. Cleaning the ball linkage helps a lot.

I think someone has already done that for you. That hole in the top of the transmission tunnel is much bigger than mine. Maybe that was done to accommodate the cranked gear lever? Anyway, it has allowed you a lot of access and made the job a lot easier.

Well done! thumbup

The hole is coincidentally the exact same size as the old gaiter. The gaiter was split, so I was happy to cut it off (I'll drill out the rivets tomorrow). My only concern is the replacement gaiter might have a smaller footprint, so some fibreglassing may yet be needed...

Must be original then and just looks larger in the photos.

Not if you've bought the correct gaiter wink

Embarrassing confession time. I started up my V8S for the first time in months today and had good feel around my gearstick and yes it's the same cranked gearlever. What a plonker jester

The new bits have arrived from Race Tech. The bushes look trivial to fit, but as you can see below the E0096 replacement gaiter is fractionally smaller than the old 6-stud gaiter I removed:





I don't know if the 6-stud gaiter was original, or the result of somebody enlarging the hole for access. I could hunt down a larger gaiter, or maybe I'll screw a sheet of fiberglass over the current hole (with a hole for the gearlever!), then screw the new gaiter to the new fiberglass. For now, I'll refit the gear lever tonight with the new bushes, and decide on a solution for the gaiter this weekend. At least without a gaiter it will be easy to check everything is still tight in a few miles time, if not a bit fumy...

Hi Ian - In this photo you can see where the front edge of the fibreglass is after I repaired the hole I had to cut to get at the bushes. You can just make out the screw holes for the front of the rubber gaiter....


In this photo you can see how the original gaiter fits and where I had to inset new fibreglass to locate everything correctly...



I did this job in 2015 and remember it being a right PIA.

Good luck - Joe
