Manual Reverse too weak

binoy29

my reverse too weak going uphill or slight uphill. it barely makes it, it feels like im going to burn my clutch if i force it to reverse on uphill. but 1-6 gears are fine. its just when i parallel park on uphill, my Z is having a hard time reversing upward, so weak. feels like the clutch grab is weak or gears are not grabbing. its bogging, it feels like engine is going to shut off. hard time reversing uphill.

anyone else experiencing this? driver error? coz iknow Z manuals are complicated. narrow clutch window? my first Z manual. im a manual driver since i was born, not new to manual.

Help whats wrong?

Same here. I have to really give it a lot of gas and can't let the clutch out very far otherwise I'll stall driving to reverse uphill if someone coming out of my underground garage is stupidly taking up the whole lane (happens a lot).

Reverse gear ratio's are usually pretty low. Not meant to pull weight. Not sure what our reverse ratio is.

Low end torque is nerfed up to 3.2k @14.7:1 A/F ratio. To fix that u need to adjust ur A/F ratio table.

I always thought reverse would be the strongest gear? Am I wrong here? I don't have any trouble but I don't exactly have monster hills here in Florida.

sorry i mean its juddery. then after i reverse then put it in idle/neutral i hear my tranny rattle i little louder. have u all experiencing this? is it charactestic of Z? or something i need to be concerned about? wanna know if we all experience this.

Ok now i understand, it turns out that the reverse gear ratio is small lets say comparing to other cars, after all this ratio was designed for a 350z DE engine where it had MORE low end torque(lots more out of the box), the situation here with VQ engine is that the low end torque is kinda nurfed i believe in order to get higher mpg ratings and low CO/CO2. Where its CPU is shooting for complete combustion @14.7:1 till 3.2k rpm. Which is good for nature, but bad if ur trying to move up hill, this is where that boost of power comes in when u pass the 3.2k rpm. Unfortunately 3.2k rpm is alot of speed at any gear even the largest ratio 1st gear.

Because of this you need to learn how to hold ur clutch and gas in an equilibrium to the torque applied and yeah slip ur clutch to move the car up hill. This means alot of clutch riding, so ur csc is going to go pretty quick. My advice to u is this learn how to apply enough gas to move the car in the place u want stop, release clutch, turn steering wheel, then clutch in and repeat rather just riding the clutch. It takes skill.

As for the shaking, its absolutely normal nissan garbage bushings. Rattle is cuz of the springs on clutch plate i believe in order to damp engine vibrations.
