Heloo Auto Transmission/Rewire Guru.
I bought a Naija used Sienna 2000 recently and I found out the gear does not pick well in gear shift two!
The gear is sharp but when it shifts to 2, no matter how I rev the accelerator it will not speed up as expected.
My Mecho said that there is no need for gear service yet.
The following repairs have been done:
1) Fuel Filter & Pump changed.
2) Nossle serviced.
The seller confirmed that he has once changed the ECU - Brian Box but he can not remember the reason for the exchange.
A rewire suggested that the issue might be the wire connection on the changed Brian Box is not properly done in respect of the Gear.
This issue has troubled my mind so much thereby coming up on this platform to seek help.
Over to you the Egnrs.
