Could the Brainbox be responsible for this anomaly or the gear requires replacement,

My car developed gear problem. The 4LO was blinking, check engine sign permanently on. On Drive mode the vehicle behaves as if on Neutral. It moves with occasional drag when driven in the morning until temperature rises n it no longer moves. Installed a Belgium uses gear n thereafter dat while driving gear selects up to gear six but d moment l slow down the vehicle doesn't accelerate until engine is turned off n restarted. Presently if u put gear in Drive and Neutral it moves forward, if u put it in Reverse it remains still doesn't move. Could Brainbox be responsible for this anomaly or the gear still requires replacement

Hi, it could be the engine going into limp mode because you have not had the issue associated with the illuminated warning light checked out. Thiis clearly needs to have an OBD scan carried out by a qualified, experienced technician. You can obtain an OBD scanner from many suppliers if you wish to carry out the procedure. Look up the procedure for getting any fault codes and then either do the work yourself or engage the services of a decent mechanic.
The engine light warn when the computer / ECU senses something wrong. I t can send a signal to the gearbox not to allow gear enagement at all pr limit the vehicle to low speed. Have this checked first, it might not be a gearbox issue at all, if the problem is not resolved please add more detail and repost the query.

Testimonial: "Thank you. The fibre of the original gear was observed burnt hence a Belgium used was installed. Still the problem persisted. Pls refer to my earlier post."

Four wheel drive

Try engaging the 4wd H when the vehicle is rolling slowly and in gear . Sometimes if the unit is actuated the gears will not line up an get stuck on the end of each other and will not mesh. If the gears are turning this is unlikely to occur and meshing is easier.. have the actuator checked (part that actually does the changing) and check the wiring or vacuum hoses if any used as there may be a leak or wiring /connector problem ( water /moisture/ dirty pins etc)

Brainbox light comes up on the dashboard after driving few kilometres. I change it with another one but still the same problem. Toyota camry 1994 model.

Well, that's the check engine light I think. It is saying something is not normal. You can read out a trouble code to give you an idea of why it is on. Turn the ignition on, but engine stopped, and with a piece of wire bridge terminals TE1 and E1 in the service terminal box, at one rear corner of the engine compartment.

The check engine light will then blink. A steady blink 4 times per sec is "all normal".

Trouble codes are 2 digits, and these will be blinked - first digit - pause - second digit - repreat.

So the oxygen sensor fail code (a common one) is 21, and will show 2 blinks - pause - 1 blink - repeat.

There are 22 of these codes

Chevrolet truck 4wd switch blinks

If they are blinking I believe it means that there are fault codes present in the pcm. You need to get the computer scaned to see if there are an codes present. If you live near an Autozone or Checker autoparts they can scan it for free.
