advice please - I need to be very careful with change up to 3rd gear with my JDM SW20 E153 gearbox. I am considering pulling the gearbox out in a few months to fix the 3rd gear synchro and probably 2nd gear while I'm at it.
While I've got the gearbox out I'm going to replace the transaxle boots. If I've got the gearbox out, what else should I replace, gearbox seals, bearings? Clutch plate?
Where do you get gearbox overhaul parts? They seem to be rare, the only kits I could find were from Cobra Transmission in the US and I'm not sure about quality of seals etc. I do have the new Toyota 2nd & 3rd synchro rings but nothing else.
Engine compression is fine, about 150psi, so I wasn't planning on dropping the engine as it looks like a much bigger job than the transmission. Is it feasible to do any clutch work removing only the transmission? I'm not having any clutch problems, simply wondering if I should replace it if the gearbox is out. One part of me says that, if it's working don't disturb it. The other part says that the part I don't replace will fail as soon as I put the car back together.
I will also be removing the turbo as it is blowing a bit of smoke on acceleration & uses a bit of oil. Plus I need to do the engine timing belt and will do the water pump while I'm there.
Thanks
