I live in Qatar and my Sequoia has 248,548 miles (+400000 km.) on it. There is a jolt that occurs when I press the accelerator. This jolt continues when the car shifts from first to second gear and from second to third. It appears that it stays in third gear even if I pass the speed at which it should transition to fourth gear. I think the transmission is "slipping", as we used to say. But, I don't know.

Need procedure for troubleshooting 4wd switching, electrical actuator status and position as well as dash indicators. Everything seems out of sync after a “professional” worked on it. Thank You in advance.

After 2006 Sequoia engine replacing old 2005 original... I used a key fob replacement company to generate new key fob. They're equipment repeatedly showed error code something about something wasn't recognizing something maybe motherboard? They couldn't get it done and returned my money... Does the replacement engine have something to do with this? I vaguely remember the mechanic which I trust saying that something was a little off but it would affect The trucks operation...

The ECU/IG fuse blows almost every time I crank it. If I disconnect the battery and leave it disconnected for long enough, I’ll be able to drive it for about a day and then it will start blowing again. I have replaced the main ECU behind the glove box didn’t fix it. I’ve disconnected the radio, power outlets, stability tilt sensor, heated seats, four-wheel-drive ECU, immobilizer ECU and electronic mirrors looking for a short. Can’t find it. Please help
