"takata recall" transmission slips in reverse surge in reverse after slip.
I have a 2003 awd v6 limited Highlander (hl) with 115,000 miles. About 200 miles ago, the transmission started slipping during the third to fourth gear shift. Hl goes into neutral, the revs go way up, then it shifts with a clunk. I can minimize the clunk from a stop by accelerating to 25 mph, taking my foot off the gas, letting the revs drop down to 1200 rpm (at which point the trans will shift to fourth gear), and then stepping on the gas. There are no problems in first, second, third or fourth gear. The car runs fine in fourth gear. It is only a problem with the third gear to fourth gear shift. Tried not using overdrive, but problem persists. This is my first problem with the hl. I always get my hl serviced at Toyota dealer at 5000 miles intervals. Dealer says the trans needs to be replaced. In California, the price is over $4500 for the "new" trans. Dealer will give me a 10% discount on parts and labor. I asked the service manager if there was a way to reprogram the transmission computer module on my 2003 Highlander. He checked and said that there was no way to re-program the module and there were no technical service bulletins on this problem. I replaced the transmission. The transmission was replaced with a "rebuilt trans" from Toyota. The transmission case is a used case, but all of the internal parts are new. I sent an e-mail to the local Toyota dealer to thank the service manager for customer service. I also asked them to forward the note about the transmission problem to the regional Toyota service representative. Other Highlander owners have similar automatic transmission problems. . Read more...
