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

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

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

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

Some "clever" photography on the parts websites laugh

This is how mine looks:




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

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

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...

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...

Cheers

Thanks for all the advice guys - the bushes are now all done:

Front ones were fairly easy:


The two at the side-back were total PIA, not helped by the bracket on the selector being 3mm narrower than would be convenient. Lost count of how many times I dropped bushes, bolts, spanners etc into the void. Generally they ended up on my drive, but some I had to fish out...


Drives significantly better now biggrin

Only two issues remain from my limited test drive. Shifting into 3rd gear crunched like I'd forgotten the clutch. Possible synchromesh, or dodgy clutch hydraulics (it was full of air when I picked it up). Only 3rd has ever crunched, and only once or twice. Second issue, not sure if it was the car or me, but I got stuck in reverse! Did a 3 point turn, went to pull away and couldn't...

Cheers

HI Steve

I fitted these, and they are poly bushes:
