#313 of 601 Toyota Tacoma transmission problems
Nov 19, 2009 (2:09 pm)
Well, hopefully good news folks. T-SB-0373-09 was just flashed (meaning downloaded) onto my Tacoma this morning by the dealer. It is titled as ECM Calibration:Enhancement to Shifting Performance & Smoothness. It says applicability is for 2009 engine 1GR Transmission 5AT which I presume is automatic 5-speed. It says " To enhance shifting performance and smoothness below 20 MPH during the 2-1 downshift on vehicles equipped with an A750 transmission, the Engine Control Module/ECM (SAE term: Powertrain Control Module/PCM) calibration has been revised. Use the following repair procedure to address the condition." Previous Calibration ID: 30449000/30449100 and the new Calibration ID: 30449200. There are 4 pages to the TSB and it seems to be directed to the 2009 model only. Don't know if it affects other years or not. I can tell you that the drive home I didn't notice the problem at all. Don't know what if anything else might be negatively affected by this at this point. To soon to tell. Why it has taken so long couldn't say other than possibly Toyota needed time to try it out. The dealer was not I repeat not aware of this new TSB (11-3-2009). You will have to tell them about it as apparently Toyota's communication system leaves a bit to be desired. Once again the TSB # is T-SB--0373-09. I still fault Toyota for not coming out and not saying they were working on the fix and would advise the dealers/customers when completed. What I can say is what a success this forum can be. It took over 300 postings of this problem to get Toyota to react. Frustrating I know but each and every one of you is responsible for this problem being addressed. Though this fix may only help a few of us (I hope not) it is because of this forum and others like it that it happened at all. Thanks. I really have my fingers crossed that this fix fixes the problem on all years of the Tacoma and other makes with this issue. Do have a good one.

Has anyone with a 2010 got this "fix" yet? post #313 stated they didn't know if it was only for 2009 or not.
#316 of 601 Can someone post a copy of TSB 0373-09

Good job on reporting there befuddled2! Does anyone have the 4 page copy of the TSB? Might be helpful for some of us who have dealers that are claiming ignorance.

I made them make a copy of it for me when I took the vehicle in. I just don't know how to copy it and post it as an attachment in this format. We're not supposed to put our email addresses on here otherwise I'd copy it and send it to whomever wanted it. For me to type it in here verbatim would take several hours and even then I wouldn't be able to put the illustrations in with it. The dealer can pull it up as it is there. Any ideas on how I get it to you?
#320 of 601 Finally, transmission fix
Nov 22, 2009 (9:39 pm)
I bought my 09 tacoma 4x4 access cab in July. Got the run around from dealer and Toyota. After reading the posts on this forum I made appointment at the dealer. Got the truck back Fri. Nov 19 after ECU re-programming, major improvement in shifting. Before, it would wait to shift (from 1st to 2nd gear) at 2400 to 2500 rpm, now it shifts at 1400 rpm without that annoying delay. As a result the truck performs better.
The work order quotes a different TSB.
"Condition : Complaint of erratic transmission shift. Seems to take awhile to shift into proper gear.
Cause: Comfirmed complaint. TSB 3111 applies, ECU requires re-flash.
Correction: Re-flashed ECU and re-checked. Okay now "

Great. Hopefully, many others will call the dealers and get this accomplished. At this point (a few days after) my truck seems and feels much better. I am optimistically hoping it continues and produces no ill side effects over time. Go forth all and lets put this problem on the back shelves. Kudo's to Toyota for stepping up to the plate. Do have a good one.

I too have the update on my 09 Tacoma and the shifting is significantly smoother. (for now). But you are correct, the dealer will not tell you of this update, I had to once again, tell them of the transmission glitch. It is unfortunate that it took so long for this issue to be addressed with all of the hassle that Toyota customers had to endure just to get their vehicle to operate as they should.
It is interesting that everyone I spoke to claimed they have never heard about the issue, but yet an update to the transmission came out? They knew about it.
These forums are important and I hope everyone continues to post issues they encounter with any company they deal with. Whether its auto related or other.
Now I just have to wait till Toyota figures out my radio issue. As it has shorted out since I bought it back in January. This is the vehicles 2nd radio to do this..
