Lexus GX 2004-09 :: GX470 Transmission Intermittently Does Not Engage Into Drive For 6 Seconds
Mar 21, 2012
I have had an issue with my GX470 almost since I bought it in 2008. It will sometimes not engage in drive after backing out of a parking space.
It usually happens when it is warm and the car has been driving for awhile then I park for lunch or an errand. I come back start up the car put it into reverse backout of the car space and nothing for a good 5-6 seconds. Seems a lot longer when cars are waiting to take your space and honking.
Anyway I have been reporting it to Lexus at every service and getting a no trouble found. Over time it is occurring more regularly and it even happened at the dealership but of course I was the only one in my car at the time.

Still having issues with the transmission on my 05 F350. I posted before that it would take a few seconds to go into drive or reverse. The fixes were to change filters and do hot flush. I had the dealer do a hot flush, and then I put about 1000 miles on it. That didn't seem to fix anything, so I went back in and asked for more info. They did not change the filters. I thought they did, but found out they did not after the fact, so I decided to change the filters myself.
The interior filter was easy to change. The fluid was clean, and the magnet had shavings on it but nothing that seemed extraordinary. The exterior filter is impossible to get off. I reviewed posts on here before trying, so first was the impact wrench, then the pipe wrench, then the pipe wrench with a block wedged in to keep the thing from bending, still no luck. The cast nut broke off well before the pipe wrench came out of the drawer. How to get that thing off. I read on here somewhere that no fluid goes through that until 180 degrees, is that correct?
Scanguage says it rarely goes over 160, except for last evening when I was stuck in traffic. It went to 187, with ECT at 208. During this period, traveling under 40 most of the time, the transmission was shifting erratically, to the point I wanted to pull over and allow it to cool down. But traffic broke free, speed went up, and temps went down. Shifting returned to normal, except when trying to engage drive or reverse. The 3-4 second delay persists at any temp, and there doesn't seem to be any slippage. Just delayed and sometimes hard engagements. I'm at a loss for whats wrong.

I have a 2006 F250 Lariat super Duty / 6.0 L engine / 143000+ miles / once started and transmission shifted into drive it takes 5 seconds or more for it to engage hard or if I build up the RMS then it jumps into gear hard, after it gets going it feels like I am driving on a washboard until it get warmed up good 10 mile or so. Is it the transmission filter and if so which one, I understand there is a small one on the outside of the transmission if so where? I can't find it.

on a 93' 4 runner that will not engage 4 wheel drive. The 4 wheel manual shifter works fine, and the linkage underneath looks fine; however, the indicator does not light up - and it definately only has rear wheel drive.

We recently had an issue with our 2011 GX460. My wife first experienced the transmission not wanting to engage after being put in drive. Once it did engage there was a loud bang/pop noise, then no issues afterwards. The same thing happened to me this weekend. It was weird, like the brakes had frozen up then suddenly released and the transmission slammed into gear. We bought the vehicle used a couple months ago with 39k miles. With factory warranty remaining it will be heading to the dealer shortly.

I have an interesting automatic transmission problem. Hot or cold makes NO difference. When the car is started, put in reverse it will work perfectly 100% of the time. When the car is started, put in Drive the transmission will slip for about 5-10 seconds before working perfectly. When the car is started, if you wait 3-5 minutes, then put it in Drive it will work perfectly.

New to my 2008 GX470. 100k miles. Love it so far. However I think I am hearing a intermittent rumbling as I drive down the road. It is like the rumble from a radio base sound. It could be normal road noise but I bet it is not.
I have replaced the left front axle (grease boot broken), replaced the rotors and pads, replaced all differential and transfer case fluids (not transmission yet) and inspected all the suspension parts.

I would like to post this performance issue on my 2003 GX470_79Kmiles which happened on the freeway yesterday. The sequence:
1) During start and at idle/stationary, the rpm shoot to 1100rpm and stayed there for a while, i would think that it was normal since the engine was still cold.
2) Drove to the freeway, I noticed that speed is very slow to pick up. My normal driving experience was that at close/equal to 2000rpm, the speed usually at around 70-75mph. But there was a considerable reduction of speed at around 60mph at almost more than 2000rpm, plus a buzzing engine noise. I tried to really rev-up the engine but very sluggish to pick up the speed not even close to 70mph.
3) Drove the car to lexus shop this morning, top speed of 60 to 65mph and tried to rev it up to plus 2000rpm to pick up speed, but the engine noise is very abnormal.

After I push the switch for the 4 wheel drive, the light on the dash blinks but the front differential won't lock in even after driving around the block.

2006 GX470, ~65k mi. When shifting from P to R, P to D, or R to D, the transmission often (but not always) seems to have to think about it a while. When it shifts fine it takes about 1sec for the transmission to change gears. When it's being cranky it takes ~4secs. There are no other symptoms.

I just purchased a used a Lexus GX470. The transmission seems to do something fairly consistently that seemed unusual to us, but we are new to this car so I'm not sure if it is normal, abnormal, or a sign of something big to come.
When starting from a complete stop, upon removing your foot from the brake, there is a noticeable mini-surge in the engine as the transmission engages, and the sensation seems to repeat when the transmission is disengaging as you brake to stop.
Does this sound normal? From searching on google, I have read that there are issues with "hard shifting" but this does not seem to happen with shifting...just when the transmission engages or disengages, and it isn't a big 'bump' as much as a mini-surge. I have also read where it could be related to something electrical such as the air conditioner.
The car is under warranty, but the service department notes no error codes when they scanned the engine.

I have had my 2007 GX for 5 months now. I have discovered the "clunk" issue and had the dealership replace the driveshaft. I want to start a new thread because I have a different clunk. The new driveshaft has fixed my clunk issue at a stop but I have one more. While driving in the city or leaving the highway on the exit ramp (transmission is in overdrive) and I press the accelerator I get a clunk.
This only happens when the transmission is shifting out of overdrive. I can repeat this clunk while driving around 30-40 mph. I will coast a bit then accelerate enough that it wants to shift out of overdrive and then "clunk". It sounds loud but not much of a jerk. I have 85K on it and did not perform any fluid changes in the drive train yet. Transmission is sealed so not sure if it is worth changing or just leave it and drive nice so it don't clunk.

I have a 2006 Gx 470, which is the wife's car.
Yesterday I couldn't drive the car when 4WD shifter was in neutral.
The transmission would not engage in R or D.
Same thing when the car was put in low for the 4WD shifter.
However, it seems to drive normally when the shifter is in H.
When I went to put the shifter in Park from either the low or Neutral position it would have a high grinding noise.
Car is in the shop as we speak.

Overhaul trans, new old pump, but doesn't engage in drive. Reverse and all three low work fine. Drive will only work when rpm's are applied. But without any power.

1991 4x4 f250 idi w e4od w 3:55 ratio... The truck is slow to engage in reverse, about 5-10 sec. It also has a very hard shift 1-2. All other shift points are good. Drop down is good, and TC lock up happens at all the right points (feels like anyway).
I've had the truck for about 2 years now, replaced several sensors an harnesses and a full fluid change to solve other problems but this still remains.
Sometimes when I start it in the morning if I let it sit and idle for a few min it will engage reverse much quicker AND shifts way smoother and constant. Shifts smoothly thro all gears, holding a constant 1800-2000 rpms with no drop or lug. Or do I need a rebuild?

Lately, I've been having an issue with my 03 GX. It seems when the engine is cold and I back out of my driveway, when I put the truck into D, I feel the usual bump into drive, then it falls off and then a harder bump before I'm able to roll forward. If I don't pay attention and accelerate at the time the transmission seems to drop out of gear momentarily, the truck slams into gear and feels like I granny dropped it.
The truck is coming up on 120K. I've checked the transmission fluid and it is at the correct level.

Its a automatic transmission with a v6 4.3 vortec. The front axle will not engage, it is not the acuator (I replaced it and the cable) you can pull the cable and the axle will engage. There is a low buzzing noise(coming from the drivers side) until you give it gas. This noise stops when the front axle is engaged. The transfer case will go from hi to low without any problems.

Just a little background, my Ex is a 2000 V10 4x4 with 217,000 miles. I've owned it for a little under a year. Very clean truck, and well maintained by previous owner. Now the issue. Starting about a month after I bought it, it would occasionally hesitate to engage drive from park. I checked fluid and it was full and clean. I had a buddy recommended that I check for chafed wires in the steering column which I did and found nothing. It seemed to get better for a while but now it's back. It's doing it more than half the time I put it in drive and sometimes takes 10-15 seconds to engage. So am I probably looking at a new trans? Or, is there anything that can be done to save the old trans?

This transmission shifted smooth and strong through all gears until today when it stopped all of a sudden to engage either Drive or Reverse. No previous signs of slippage, hesitation, stalling or lack of power whatsoever.
We checked the linkage to the transmission and it works as intended, nothing loose or broken, everything is in place. If there was something slightly different with it from other similar vans we have then it had a slightly delayed engagement in Drive (it took a second to engage it after you moved the lever) - on all other vans we have the transmission go into Drive almost instantly.
Van is a '92 Pontiac Trans Sport/Chevrolet Lumina APV with the 3.1L V6 Chevy TBI engine with the 3T40 automatic transaxle. Where we should start tackling this issue?

I have a 1999 F250 super duty that blew a front seal on the transmission two weeks ago. I sent it to a shop and they replaced the seal, and torque converter. However when they put it back in it will not engage in drive or reverse. After working on it several days we replaced the transmission with another one from a service company. This replacement came with a 90 day warranty. However once it was installed it does the same thing and will not engage in drive, or reverse. I am not sure what is going on but with two doing the same thing it makes me thing maybe electrical or something else.
