Replying to: camryowner1 (Aug 21, 2007 6:23 am) Sorry, you have just arrived in the future...! Both of the vehicles I rented while on vacation this year would shift so often it made me think something was wrong. The first was a 2007 Mazda minivan and I was totally convinced it had some strange transaxle behavior until I rented a 2007 Chrysler Sebring the next week and if anything found it was even worse. These days everthing possible is being done to keep the engine operating within its best FE "sweet spot", the lowest possible RPM at which the engine will just barely produce the level of HP/torque required in the instantaneous, short term, sense. Then throw in the need to have the transaxle ALWAYS upshift upon a lift-throttle event to increase the vehicles safety factor by avoid any substantial level of engine compression braking and you have TOO MANY SHIFTS Take a 6 speed automatic transaxle with a lockup clutch for the torque converter and you essentially now have a 9 "speed" transaxle. To the benefit of improving FE Lockup clutches are now being used, engaged, in gear ratios below OD. Maybe an effort is afoot to try and match the FE that can be attained with some of the new CVT equipped vehciles. |

Replying to: nathan118 (Aug 20, 2007 3:55 pm) They made me go on a road test with a service technician. He was nice, and they decided they could look at improving the transmission performance. Two hours later I get the car back, and the operation that was performed is "EG7031." That doesn't look at all like the new TSB Joel is raving about. The ride home was mixed. I'll give it a few days, and if they haven't done this newest TSB, I'll try and take it back, or find a place that will do it when I ask them to. Any thoughts on what the EG7031 is? Thanks guys. |

Again, just to be clear, I have a 2007 4cyl 5spd automatic XLE Camry. Here's the information from my TSB Number = EG036-07 Title: ECM Calibration: Enhancement to shifting performance & smoothness Note: This TSB supersedes TSB No. EG056-06 (obsolete and should be discarded) Applicable Vehicles: 2007 Model Year Camry vehicles equipped with 2AZ-FE engine Applicable Warranty: This repair is covered under the Toyota Federal Emissions Warranty. This warranty is in effect for 96 months or 80,000 miles, whichever occurs first, from the vehicle's in-service date.

Replying to: nathan118 (Aug 21, 2007 11:08 am) Hmm, I have a subscription to TundraSolutions.com which lists all the 2007 Camry TSBs. I don't see anything that matches the TSB you mentioned. Could it be brand new? Also, your TSB is missing a number. Here are all of them that start with EG: EG004-07 M.I.L. ON DTC P0011, P0012, OR P0016 EG014-07 M.I.L. ON DTC P0456 (REVISED) EG015-07 2AZ-FE ENGINE BLOCK EG018-02 2GR-FE ENGINE OIL LEAK FROM FRONT TIMING COVER EG018-06 ILSAC GF-4 ENGINE OIL RECOMMENDATION EG034-07 ENGINE BANK 1 AND BANK 2 A/F AND O2 IDENTIFICATION EG038-06 2GR-FE (V6) ENGINE OIL LEAK (REVISED) EG039-06 EXCESSIVE ENGINE NOISE AFTER TRANSAXLE REMOVAL EG056-06 ECM CALIBRATION: ENHANCEMENT TO SHIFTING PERFORMANCE & SMOOTHNESS (REVISED)
