Hi all, Firstly if anyone wants to text me or CALL me with information please do 04211802580 Im from Melbourne. Unsure if this was the right section but I want to discuss if the T5 gearbox that is in my car now ( along with its flywheel, tailshaft, pedeal box, new clutch and spigot bush and cable setup up, not the loom as they have just cut the wires needed or the speedo and reverse light ) was there one major step that could have been over looked as my car is vibrating like crazy. At 2,000rpm the gear shift knob which isnt securely on just rattled and popped off thats how bad it is. And i think the vibration kind of settles when revs go down...whatever Im so stressed here just trying to give every detail I can. I have gathered the following information to resolve this issue I have been told the flywheel (which was machined) could be 180 degrees out as one of the holes are offset The flywheel needs to be balanced to the crank which ends up costing a lot or a rebuild of the engine. Or balance it to the Getrags flywheel (I do not understand that at all same engines but yes one is dual mass so whats the deal?) It could be the harmonic balancer (thats the engine part so what no?) or a thrust bearing. But it is the gearbox engine was fine before. I initially thought it could be the mounts on the gearbox but no its not. Diagnosis Report I put the clutch pedal in and bring it up, when up (simplest way of describing this) a noise is happening. Have been told to balance the tailshaft but unsure to trust them with that if theres a noise from the clutch too. They have phoned around and a wreckers in Queensland said "you need to balance the flywheel to the crank" and even the local shop that does the balancing is like "we could try to balance it to the Getrags flywheel" and I just dont want them to take it any further as its not sounding like.....thats the guarantee fix. The car is going to Just commdores wreckers in Reservoir as the sound like they know what to look at. But didn't confirm if they ever came across this situation fully hmmmm but its my best option time wise. Any thoughts? The clutch people gave me a clutch for a vn but its the same clutch as t5 was for vn to vs s1. And I have a 96 vs which had the getrag and bad spigot bush and didnt want to have issues with it. And got a t5 gearbox from a VS 95 which its engine was misfiring and picked up a bit when I changed the plugs between the two but wasn't vibrating at the gear stick like it is now in my car. I wanted to get it roadworthy and going on the road so quick after this gearbox was in. I am starting my mechanic apprenticeship I am hungry for the knowledge and skills of the trade. Thanks for having a read. Appreciate it. Again, if anyone wants to text em or CALL me with information please do 04211802580 Im from Melbourne.
