I did a gearbox overhaul from them in my previous presea... after the overhaul it felt good, like the gearbox was smooth, better pickup and gear change and they give a 6 month warranty too.. costed me only 28k for the overhaul and 6k for the gear oil, so its worth it.. after all its your own gearbox you repair, and you never know the condition of a reconditioned gearbox you buy.. I drove for 7 months after the overhaul and sold the car, i didnt have a problem with it.. im sure the new owner doesnt have any problem with it yet so far, cuz if there is a problem she would let me know... no complaints that means the car is still running good after a year.
