4WD/Transmission failure 2008 Tundra 5.7 6 sp? by mcsmadison

My 2008 Tundra's tranmission went out last week when attempting to shift from 4 WD high, into 4wd lo, then back into high.
 
I was stuck in the snow in 4wd high, then tried low, to no avail, tried the tranmission in lo (which didn't engage--just 'lo' light blinking and alarm buzzer, then tried 4wd HI and there was NO transmission response, a grinding in "P' and no low, high, or anything--from Park to D, Reverse, all the gears were gone, and I was getting ready to call for a tow truck, and after grinding the P gear for a while and back into N, it went into 4wd high.
 
Toyota replicated the problem, after some doing, and they're trying to fix it as the 4wd acuator is a problem--it's backordered to Japan which means the truck is out of action for a month.
 
There are similar reports of damage and problems listed on the NHTSA website.

I have the exact same problem on my 2007 5.7 LT w/only 12k miles. I just shifted into 4 low to try to get up from my driveway onto my hill to get some firewood replenished and got the same blinking light on my 4 low indicator, the same grinding into park, etc... Unfortunately I can't get it to come back like you did, so no lower to the wheels. I called a tow truck and the flatbed was too short in the end to load from the bed side... so after reading your post I'm going to go back out and try to jolt it back into gear! Thanks for the hope. Glad this didn't happen in the snow somewhere remote! Sounds like a real toyota problem...

Sorry to hear you've had the same problem with the transmission/xfer case--when I read of the problems on NHTSA website that other people had similar to ours, I was really disappointed that this was happening on a Toyota for more than just myself... I guess as frustrated as I was, I was glad to know that when the transmission fails, (no gears after the 4wd problem) that the truck wasn't left in park just to accidently roll down a hill and into someone, or over them....that would be bad....the one complaint on the NHTSA had a truck with the same problem roll down into a garage and cause 5K in damage but no one was hurt...
 
Like you, I was ready to call the tow truck (stuck in the middle of the street) and as you say fortunately not out somewhere really far away from anywhere but I was on enough of a hill I let the truck roll backwards about 20 ft in N or P and in 2wd and eventually a clunk sound and was acting ready to drive again...but this did not make me feel anybetter--in fact I was feeling less settled and more ticked off than ever--wondering what kind of 30,000 dollar junk was this?
 
The truck's been down for almost 40 days now, one problem after the other, the dealership has done what they can, Toyota HQ is now aware that I am not pleased in any way...but they aren't doing much...funny how as I type this there is an add for a new tundra! All I can say is whatever remedy they propose ought to be really good and swift--probably the last toyota I ever buy--which I say after having Toyotas in the family for 28 years.
 
Good luck with yours--I hope your situation pans out better than mine.

Wow that doesn't sound good... Your post is the first one I found after doing a Google search so I haven't seen any of the NHTSA compliants.
 
I couldn't get the truck going again. The battery was dead when I went back out - I think the 4 wd actuator was continuing to run in a loop trying to get the truck out of 4 low even with the key out. I could hear it switching. I think that ran the battery down. I'm charging that now but don't expect anything good.
 
To make matters worse, a flat bed came out, I struggled but got my huge dead truck loaded on it only to find out that the truck was too long for the flat bed. The tow guy told me that he could only fit it on front forward and there was no way to do that with the way the truck is situated... so I'm stuck calling the dealership in the morning for help.........
 
Anyway I'm writing this to help any others that might find this info useful.
 
Toyota - oh what a feeling.............

An update for posterity:
 
I don't know what did it, but when I went out this morning, took the charging cables off the battery, and started the truck it was in 4 high and the wheels were engaged (I left the switch in the 4 high position overnight). The 4 low light was no longer blinking like it was last night when I left it to charge.
 
I don't know if it was moving the truck back and forth off/on the flat bed, or the battery going dead... or what, but it managed to get itself back in driving shape. I didn't turn it off or shift out of 4 high - just drove it straight to the dealer in 4 high.
 
I'll make one more update with the dealer's findings. I hope this helps someone... and I hope Toyota fixes this thing properly!

MCSMadison,
 
Don't know if you're still monitoring this feed... but I'd appreciate any more info on your specific dealer findings if you have them (e.g. what specifically was wrong (4wd actuator?) and how they reproduced if you know). My dealer is having trouble reproducing this and is starting to push for me to take the vehicle home. No way am I doing that without a big ole' fight!
 
Thanks again for the trouble.
 
Matt
