now the gear change isn't clean
Discussion
Changed the gear box oil on 350i put ATF in.Was fine then 100miles or so on went to go from 5th to 3rd couldn't get it out of 5th at first, made a balls of the corner I wanted 3rd for, then got it out of 5th. All gears are now selectable but not cleanly, have to really coax them in and still get embarassing noises. cluch seems ok from stationary, but have bled the black fluid out, thought it might be a bit of air.
The car has been an oily mess underneath since I got it both engine and gearbox. Was to be a winter project to pull the engine out and do all the seals. I am thinking sticking clutch due to all the mis-placed oil and I don,t have time to pull the engine out just now and its summer!
Any ideas for a quicker fix guys or do you think its even worse and Ive shagged the gear box???

Had a similar problem myself last year, started off with slight snagging 5th to 4th then soon developed into bad snagging 5th, 4th and 3rd whichever way I changed. I suspected the worse and got some prices for getting the box overhauled, decided I would take it out myself to save some pennies. After I had removed the interior trim and gator I noticed that the 4 little rubber bushes on the remote linkage were shot. I bought a set for nine pounds, spent about an hour fitting them, went for a drive and the gear change was perfect in every gear! No problems since!! Could well be worth a check on yours. If you get hold of the lever try pulling it up and down verticaly to check for movement, the stiffness of the gator was masking the problem on mine.
I changed the oil and the gear change was also crap I got out and checked the clutch fluid just in case!. I have to let the car warm up a bit before the change comes back to normal.
I used TVR recommended stuff in the change. The gears and the actual change is fine once the car has gone a few miles.

Thanks for all the help. I am back home now so I can start trying to sort Trevor out.
Oil level is where it should be 2-3mm below the level plug.
I forgot to mention that the oil change was prompted because I was getting snicks when engaging 5th and the oil was 750ml short of where it should have been when I filled it back up again!
Checked the vertical play in the gear lever its about 1-2cms, oh joy it could be easy to fix. Please where do I get the bushes from and part nos?
I am off to bleed the clutch again, hope I am wrong but the last time I had this sort of problem (not on a TVR)there was a couple of tynes broken where the thrust bearing hits the clutch diaphragm, can,t get it out of my head, please, please guyes prove me wrong.
Bushes first then any more straws to clutch at please, no pun intended!!!

Bloomin marvelous.. Having followed the story so far I went and checked the lift in my gear stick. Yep about three foot. Stripped the boot and centre console down and found there is more movement in the gearbox housing than in the gear stick itself...The bushes are totaly sh***d. There will be a phone call to Rimmer Bros in the morning. I will let you know how I get on...
I think some-one else said they used some bits of old 19mm copper piping instead of the bushes, which worked fine. Presumably it compresses a bit as you tighten the bolts.
On a related note I now think the noises in the 400SX are coming from the gearbox, not the diff. I checked the g'b oil over the weekend and there appears to be ATF in there, not too murky, just a few bits of shrapnel.
I just bought some Castrol 75/90W to replace it with in case the ATF is a little thin to cope with 340-ish lbf of torque! Hopefully it'll last a little longer, though I might go down the rebuild route suggested by Steve H in another thread to get a bulletproof box.

You may find that the shift is a bit stiff and clunky while it warms up using 75/90.
As I said in my earlier post, a good multigrade seems to be a nice compromise between ATF and trad gearbox oil.
It actually turned out to be Unipart 75/90W, yes the gearchange is a little clunky at first, but I always have a mile to drive out of the village at 30mph so that's fine.
The zinging noise seems to be less apparent, at least it hasn't got any worse. It's in 3rd (a little) and 4th and 5th mainly. Now I know the oil is fresh and clean the only other gotcha might be the oil pump in the box. However, if that goes, it's a box out job anyway, so I may as well just keep driving it.
I replaced all with Castrol SMX-S a while back and I've just realised that the zinging has abated somewhat, and the gearchange is also better with this oil.

Bloomin great. What a differance new poly bushes make. Cleared up three problems 1.Getting reverse,now I think Im in first in goes in that easily. 2.Got reverse lights to work as the extra movement was trashing the end of the switch 3.And this is a maybe? stopped a rumble when you start the engine (presume housing rattling).
At what cost though - fibre glass rash,large bruise on back of arm and the religious neighbours not talking to me due to the bad language!!!
What a pig job I shake the guys hand who did it in an hour. The poly bushes do not have any give so when attempting the side mounts you have to use some leverage to get the last one in (long screw driver).
A job worth doing so check yours N O W !!!
Poly bushes just under £20.00 from Rimmer Bros on next day.

Done mine and only got a slight improvement but at least its drivable now. got to change the oil again then its back to the clutch if the oil change doesn't cure it. i had to use the original plain rubber washers on the front /top/most inaccessible whatever you want to call them bushes as the poly bushes were too thin on thier own, took a while to twig that the originals were two bushes stuck together a plain rubber washer and a stepped bush like the rimmer bros replacements.
have to agree that the language wasn't to pleasant, cries of where's the little yellow bastard gone now, which soddin ledge has it landed on this time.
