You may want to check your u joints also, that could be the banging

The gearbox mount needs to be replaced. On hoist, drop exhaust, r & r mount.

Screeching is possibly the clutch throw out bearing.

2000 Saturn Vue, manual transmission 5 spd, trouble shifting, loud knock (more like a BANG), when shifting into 1st gear... ..constant rattle while driving.....????


Try shifting into first without pressing the gas. If it is a slow decline before engine dies this is normal. If its a dramatic engine death, your clutch is to blame, if it still makes noise then its the gearbox. If you have a Mr. Clutch Autocentre near you they will test your gearbox for free as will many reputable transmission shops.

Gearbox feels like it slips.


You indicated 1st gear. Is this a manual or automatic - as you didn't state that.

What do you mean by "it feels like its going to fall out"? What are the symptoms?

Have you check the level of transmission fluid?

Can the transmission be serviced or is it one of thos "life-time fills"? If it can be serviced and its an automatic, the first thing I would do is check the level of fluid. If its a manual transmission, I would do the same thing, but it would most likely be the clutch or throw-out bearing.

90 300zx TT have to press on gas paddle to start


Sounds like you need some new spark plugs and plug wires. They don't work very well at all when Cold, or under moderate to heavy acceleration

300Zx will not shift out of 5th gear


is there any pedal pressure when you step on the clutch? I had a similiar problem with my 91 300zx tt....it was stuck in third gear, no pedal pressure on the clutch whatsoever....i had cracked the pivot ball and the clutch slave 'popped out'. i had to pull the trans to fx the problem because i could not reattach the clutch fork onto the release bearing with the trans in the vehicle....you need to bleed the system...gravity bleed the slave until there are no air bubbles. make sure you top off the clutch master cylinder in the process.....then bleed the clutch operating cylinder.....it is in the passenger front hood near the power steering resivoir....top off the clutch master cylinder again. i hope this helps.

Original rear wing 1990 300zx z32 need to know were to get one


You may have to look at Kaminari - they're an aftermarket company that makes a wing similar to the OEM TT wing. You may have luck with Courtesy Nissan in Texas though - they have a ton of stuff there (www.courtesyparts.com). Or if you don't mind one that is used, call up Z1 Motorsports in GA (www.z1motorsports.com) - they're a 300ZX salvage yard and tuning company. They'll have one for sure.
