This is a question for my dads 2001 Tundra v8 Limited. He called me up and told me about some of the problems he was having with the 4 wheel drive on the truck. He said it would not engage when he tried to press the 4hi button? I don't know much about how the 4x4 works on these trucks but I am hoping someone on here does. The truck has 150000kms and recently had its transmission replaced (1-2months ago) and this is what was happening before the tranny went. He brought the truckin thinking there was something wrong with the electrical on the 4 wheel drive but was soon to figure out after the great toyota service techs sent him on his way that it was that his tranny blew. Well I hope someone on here can enlighten us and help us diagnose the problem before we spend more hours and money at the Dealer.

 

I don't know if he tried to speed up or slow down while it was on. My '02 4Runner takes a few minutes sometimes before it engages. Try driving and engageing it and drive a little speed up slowly and slow down. From what I read here it has something to do with things spinning at the proper speeds.

 

no its not that....he said he's tried it at different speeds. The 4Hi light just blinks when he tries to engage it? I asked him to check the fluid levels but I doubt that would it since they checked them when the tranny was replaced.

 

Try posting in "4Runners, Trucks and SUV's. More people read that. I bet they can help out.
