Hi all,
recently encountered some problem with my reverse gear.
after a certain period of forward drive, when i switch to reverse,
my car will stall for 1 to 3 sec before it engage into reverse, and comes with quite a jerk.
when i go back to D and R again, the jerk still exist but less violent.
but when i D for some distance and R again, whole cycle repeats.

now the symptom became worse, sometimes when i R, i feel totally no engagement on my R, and i need to step hard on my brake while lightly tap the accelerator to "engage" the reverse, and of course, with the compliment of the rather hard jerk to the car.
I went to TC for a look and they told me its most likely GB issue. tell me to either overhaul it or change it. I ask them is there anything i can change to salvage the GB as my car only let 3yrs+, they say nothing. but from some online forums i read there are still a few things to try before it reaches GB stage.
so from the symptom confirm is my GB problem? and the only soultion is to either change or overhaul?
thanks in advance for the advices.
