v160 gearbox reverse issue

Hi All,

 

Have a problem with my supra going into reverse.

The problem starts when the car has had a chance to warm up 15+ minutes, first time after warm up it is a normally ok but then after stopping and trying reverse again it becomes a bit difficult to put into reverse a tad notchy, them maybe after 3-4 more times of stopping the car and putting into reverse again it just will not go into reverse!

I've tried pumping the clutch that doesn't seem to help at all, clutch has been bled to make sure there is no air in there and also a change of the gearbox fluid to royal purple synchomax, still hasn't helped!

 

Wonder if someone has any suggestions on what could resolve this issue?

I have a feeling this will need to go for a rebuild, if so where can this be done?

 

Thanks,

J

Hi Chris,

 

When the engine is not running it will go in a little, then hesitate then go in fully but with a slight clonk.

1st gear i think is ok? I'll have to check next weekend.

I would suspect the clutch. I see loads of this. You *COULD* and just *TEMPORARILY* take all the play out of the clutch pedal pushrod, even preload it a tiny bit, and see if it then goes in to gear OK. If it does it's definitely a clutch related issue. But do not leave it like that, it will knacker the bearing and possibly the crank thrust bearings, just use it as BRIEF test!

Thanks for your suggestions Chris.

Because this clutch had only been fitted recently, do you think it could've been fitted incorrectly?

Hi mate, I had a problem with reverse on my car recently, then it would not engae at all and was clunking into other gears as well, when you waggle the gear lever does it feel very loose? It may not be related to my issue at all but if it is mine was a simple fix, link to thread below:

Hope this helps and its a simple fix for you like it was for me.
