Has anyone come across the following?

Recently installed a gearbox from a wrecker and a brand new clutch - when the car heats up this box was getting hard to go from neutral to 1st gear (it almost feels locked out until forced). Not all the time though, but the majority of the time. Second gear would give similar problems. 3rd 4th 5th all fine.

I took this back to the wrecker and got a replacement, however this replacement is doing the same, and now crunches a bit in reverse.

Has anyone experienced similar? Any suggestions?

Friends have suggested the clutch not disengaging properly, but what steps can be done to verify? Is it just another shagged gearbox?

mine does the same crap im putting up with it till it blows and then im getting a whole new gearbox

put thicker oil in it. the oil in it now must be gettin to thin when it heats up

Im not opposed to fixing the problem, as i wish to the sell the car and want it to be fine.

It has Redline in at the moment (fresh) ..so Oil isnt the issue.

I am interested in this Slave/Master cyl issue, but would like more info on it..

What am i looking for when inspecting the units?

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
