Hello everyone, i have Land crusier 4.7 petrol. It has started an issue, when its cold and you shift directly to R it takes 1 sec or so then shifts with jerk. It only happens in R. When its warmed up it shifts smoothly. And whole day it behaves absolutely normal. Fluid level is okay and the guy from whom i bought says he has changed it and seems fresh. There is no issue at all in shifting during drive. Reading few forum, they say add more fluid half quarter. Or adjust rpm. Any suggestions from your sides please?
