#542 of 601 Sold my 2009 Tacoma
Jun 06, 2010 (8:22 pm)
I am a Toyota fan, always have been, but I only owned my 2009 Tacoma Pre-Runner Double-Cab for 1 1/2 years. I was tired of the surging at low speeds from the Transmission. The dealer said that is the way a truck is....well I don't believe that. This was the 3rd Toyota truck I have owned and the older ones did not make me afriad to own. My truck was made in Tijuanna Mexico...which is not the best city in the world and I am not sure what Toyota has become.
I have friends that work for Toyota and I know Toyota is involved in the community in Torrance, CA....where the US headquarters is located. That is all great but the Tacoma is outdated, too expensive and the TRANNY is horrible.
I finally found a link from this Forum for a Service Bulletin to get the problem fixed since the dealer could not find it or figure it out. It was fixed, but still not perfect, so I gave up and bought a Kia. Yes I did.
I only hope Toyota gets better and stops making short cuts. Redo the Tacoma and completely re-engineer the Tranny.

I have also had that problem twice.... I have an 05 extended V6 6-speed 4WD. I had it happen to me once when I first bought the truck and just recently this week. I was wondering when this happened to anyone how where you driving your truck and maybe an explanation because the stealership keeps doing the run around like the always do! I was towing two honda sport atvs up one of our colorado passes and it just dropped a whole bunch of oil from on top of the transmission/transfer case. Also I have a CDL and have been driving this pass for years ... so I know that is wasn't the way I drive and the two place trailer wasn't too much weight.... so if anybody has anything please let me know ... my warranty expires the 28th .... and I HAVE TO PAY 90$ just to let the mechanic look at it and see if its under warranty (its a "bumper to bumper" warranty) ... after this probably never buy another toy again thanks

I have an 08 Tacoma Double cab TRD and It does the darnest things. If I am at a red light I swore that someone bumped into me because the transmission shifts while sitting still. Sometimes I will go to take off and it will be sluggish and then take off like a bat out of hell. It shifts weird and unpredictable. I have 17,000 miles on it and will not let my son or wife drive this thing. Until the competition can build a 5 passenger truck that can tow 6500 pounds and get 21mpg I guess I am stuck with it. Are you listening Ford??????
#546 of 601 99 Tacoma redlines before shifting
Jun 10, 2010 (3:35 pm)
Greetings, was wondering if anyone has any thoughts on why my 99 Tacoma's automatic tranny suddenly started redlining be fore finally shifting up (HARD). Fluid is fresh and clean and no lights have lit on the dash... 160k miles and have never had ANY tranny issues before (believe it or not). Hoping for some insight, thanks in advance.

Man, I wish I could explain it. The more stories I read and hear about autos anymore the more convinced I become that electronics on automobiles is not necessarily a good idea. The reliability factor of computers and sensors is not there and therefore dangerous. I wish you well.

Not sure if this will help on your Taco, but it's almost a sure-fire fix on older domestic transmissions. The symptoms indicate either a vacuum leak between the intake manifold and the transmission's shift modulator valve or a faulty shift modulator valve in the transmission (diaphragm or o-ring, possibly). Check for vacuum leaks first at the manifold and transmission then along the vacuum hose between the two. Usually, just replacing the old vacuum line will do the trick.
Hope this helps,

Sorry, SOP, YOU'RE the one at fault.
These days with fuel prices as high as they are, and along with the emissions issue, it would be UTTERLY STUPID for an automotive engine and transmission, drive train, manufacturer to continue to maintain ATF line pressure at a high level when the transmission is placed in neutral or park. Shift the tranny into a drive position with the engine idling and of course it might take 1-2 seconds to build, re-build, enough ATF line pressure to satisfy the valve body operational requirements and then enough additional pressure to actually engage, fully and firmly engage, the necessary drum clutches, 1st gear, HIGH torque, drum clutches.
And all the while, of course, the engine remains at idle regardless of gas pedal position.
Either buy a stick shift, stop complaining, or learn to live with the issue. Your vehicle was not designed to be shifted into neutral in those circumstances. The new torque converters equipped with lockup clutches have such weak torque coupling charactoristics with the engine at idle that the FE gain using your shifting procedure is probably negligible.

"..What's wrong with a throttle cable.."
Ask that of an owner of a 99 or '00 RX300 that has had the transaxle replaced prior to 80,000 miles, maybe even 2 or 3 times and the latter ones often at least partially, if not altogether, on the owners nickel.
With the abolition of the old style ATF pump, pressure relief spring valve and pressure holding accumulator in these new transmissions to improve FE the engine MUST be held at bay, IGNORING the gas pedal position until such time as a newly selected gear ratio's drum clutches can be fully and firmly engaged.
The early RX300's did not have DBW so the engine RPM would rise in direct response to gas pedal position, all the while the drum clutches were in the process of being "meshed".
By '01 Toyota had somewhat alleviated the problem by reprogramming the engine/transaxle ECU firmware in order to sustain the ATF line pressure at a somewhat higher average level. The transaxle premature failure numbers declined accordingly.
What we got, owners of '01 to '03, was ATF that was so overheated that the recommended maintainance schedule for an ATF drain/flush/refill went from infinity (life of the vehicle) to ~15,000 miles or signs of ATF degradation, whichever cam first.
The RX330 came with DBW and its own set of problems as a result. 1-2 second re-acceleration delay/hesitation soon became the NORM throughout the Toyota/Lexus/Scion fleet.

"..there is definitely a fix..."
No, there is only a PARTIAL fix. Only some instances of the 1-2 second re-acceleration downshift delay might be eliminated, mostly those wherein the driver "knows' the future, immediate future.
See post # 510 for a definitive explanation.
