8.5.5. Check of the moments of gear shifting

PERFORMANCE ORDER
1) check the gear shifting moments if transfers are switched too early or too late
2) do a bit of traveling on the car on all transfers under all road conditions. Do not inspect in road conditions in the presence of obvious mechanical damages
Prevention

At check of the moments of gear shifting, do not forget that indications of a speedometer can vary in view of tolerances by production.


 
3) define, at what speed there is a switching of transfer and compare the received values to data in the table
4) transfers should be switched easily and quickly, without loss of capacity of a drive
5) listen, whether operation of the engine at gear shifting is accelerated. If it occurs, it testifies that brake tapes and couplings slip
6) after check in road conditions, check a transmission on tightness

If the moments of gear shifting are not true or lower transfers do not join, check adjustment of a rope of management by a butterfly valve and a rope of a pedal of an accelerator.
