#1 of 26 4WD/Transmission failure 2008 Tundra 5.7 6 sp?
Jan 06, 2009 (11:51 am)
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!

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.

Help My 07 Tundra has a scrambled transmission display after fixing my trailer plug. 4 lo came on VSC came check engine came on No manual shifting was possible.Truck is drivable but had severe brake lockup of Tundras brakes with trailer in tow. My Mechanic hooked up Genisys systems analyzer we came up with a transmission range sensor problem. New safety neutral switch was crossreference fro Toyota parts now installed with some improvement. All warning lights are still on and no backup lights will come on when in reverse. Severe brake lockup has discontinued. My Mechanic recomends a tran shop that has better diagnostics equipment . Any solutions out there. Still driving. but nervous

My 2010 Tundra's tranmission went out last week when attempting to shift from 4 WD high, into 4wd lo, then back into high. Transmission was not responding in any gear and it was making grinding noise when shifted to P. I called dealer and aranged for a tow truck to be towed away next day morning since it was stuck in 4 WD low and no motion I read your thread and accepted it as it must be a dealer job now. Next day morning I started the truck let it warmed up and shifted from 4 WD low to 4 WD High. It shifted and running again. I think when I was stuck in snow previous night I kept changing gear from D to 4Wd Low to 4wd High then low again kept accerlating kept spining the wheels again and again .The Transmissin fluid or rear diffrencel oil got very hot and it stoped working when it cooled down over night it started working again.Try this before you call tow truck. Good Luck. Never Never shift in to 4WD Low Gear thats where the problem arise.
#9 of 26 Similar experience with 2008 Tundra 4WD

To: mcsmadison, nn201, mattinboston:
I have a 08 single cab Tundra with 5.7L V8, 6 spd transmission purchased used, with 41,000 mi. I always want to know the reason the last owner sold the vehicle, and I usually find out about 5 days after the used car warranty runs out. Such is the case here.
Several days after I purchased the truck, I took it out back in the pasture in deep snow to try out 4WD Hi and Lo. 4WD hi worked great, but, when I put it into 4WD lo, the 4WD lo lite came on and there was alot of beeping. I experienced the grinding and loss of any gearing described in the forum.
Shut the truck off and started it again, this time putting it in neutral, then switching to 4WD lo. It worked this time and I got to try lo ratio as well.
Fast forward 3 months later.........left the truck in 4WD Hi in the driveway and when I came out to start it , we were in the middle of a big February thaw with temperatures of ~60F. This was the first time since I have bought the truck that the temperature was this high above freezing.
At start, check engine light was on, and 4WD LO lamp as well as VSC off lamp were blinking on and off. I drove out on the highway but the truck would not up-shift beyond 4th gear.
(after I got out of my snowy driveway, I put the truck in 2wd and it appeared to shut off the 4WD Hi lamp). It was indeed in 2WD.
VSC off and 4WD lo lamps were blinking the whole time.
Later I hooked up the laptop to the OBD-2 connector and ran a scan. I got code PO328 which is a code for "knock sensor, bank 1, high input". There were no transmission type codes in the computer. I tried to clear it but it kept coming back (note: the engine is running quietly and smooth the whole time).
In my case the vehicle DOES work in 4WD hi, but it won't go into 4WD Low.
At this point, I am totally confused. I can hear a DC motor whirring when switching from 2WD to 4WD hi and back. No such whirring when selecting 4WD Lo.
At this point, I would be VERY interested in what the three of you have found in your search. I have low to no confidence that the dealer who sold me the truck will be of any help unless I am willing to shovel out big bucks. So far, I am comitted to troubleshooting this myself and identifying a problem before I go to the dealer.
Other than the experience of the 3 of you in this forum, I haven't found anything on the internet that relates to this problem. Is this a systemic problem with the Tundra 4WD Transfer case actuator? It seems like it is a little ridiculous to have a gear-motor assembly actuate the 3 modes when a lever could do it just as easily.
Thanks in advance for any info you can share...............
I will try to see if there are any obvious problems with the 4WD transfer case actuator

I got my Toyota dealer to replace my 4wd actuator under warranty as a safety issue. The problem did not reoccur.
Good luck! It's a bugger of a problem.
