Hi,good people.My nissan B15 cant move up a steep hill even when i put 1st gear.its automatic gearbox seems not to transfer power to the wheels.does any one know of a good mechanic who can sort me.thanks.

@Man,
Have you checked the ATF level?

@Mantosha,
Check oil level.......happens if your jinga fundi replenished your gearbox with oil while it was on neutral gear,thus isolating some compartments......The other thing is,you may have lost your gearbox and i doubt there are many mechanics who know how to repair or service planetary gearboxes.You may have to replace it,which would be cheaper in the long run.....just some opinion.

I strongly agree with impunity; our mechanics are seldom well equiped with modern technology to detect such problems nor do they have the requisite skills. Majority of them have not kept pace with the rapidly changing technology. As a result, they end up damaging rather than repairing.
Nevertheless, i recommend that you find a good mechanic who can diagnose the problem before incurring huge expenses.These good mechanics dont come cheap, but their service is reliable and can reduce the overall cost of maintenance.

the atf is fine.my local mechanic suspects the auto clutch is kaput.recommends that i save myself mental stress by simply buying a new gearbox.i just wanted more opinions .

@mantosha. Is it that your B15 cant go uphill or does it go("crawl") up hill very slowly without engaging the right gear?. I experienced uphill "crawling" with my B15 and it turned out that it was a problem with the airflow sensor. If it totally cant move uphill then it could be the gear box

@digitali, good point. Incidentally, my problem was fixed by replacing both the air flow sensor and the Engine control Unit. A proper diagnosis is in order.

@mantosha,
the school of hard knocks offers nothing but the truth. why do u you continue refusing to listen to them that sit under the iroko tree ?

My take

<<Problem- intermitent gearing problem. Switching off, pressing the accel with gear in, may engage the gears. Embarassing in parking lots and unpredictable. >>> ANSWER- THE CLUTCH IN THE PLANETARY GEARBOX IS ON ITS LAST DAYS- READ DEAD. Do not Bother opening the Gearbox to Repair.>

Your Choices:-

0- U change the ATF = The problem worsens, remains.
1. You take digitali advice- the sensors will report a code... u part with 3k or more. Time for Scarface, the Kanunga mechanic.

2. You buy useless sensors blah blah. Nothing doing.

3. You take ua car somewhere near Kobil Langata to a fellow claiming he is relatives to Obama and he's educated in USA. He fries u 12k, shares a few sensors from u limo.

4. He refers u to his cousin near Karen Roundabout - 3k towing fee, who has a working computer.. blah blah.. Still nothing...tears, time wasted. money gone

5. Finally u go to Used part Importers [with own Repair shops], pay a deposit for good Gearbox, ATF, Diagnostics and labour .one sum.

6 After one day , Kila kitu bei moja, u drive off happy.

7. Being Happy for Wazua, you donate all u can to Sk Charity for a good cause.

Now which one shall it be? Come back and lets know how it works out. In the mean time, tongue in cheek, avoid carrying your mother in law or stocks in dat limo. The aibu can be .... unwelcome.

thanks for your responses.very helpful.so next week am off to 'inda' to get my self a fresh gearbox.
