Replying to: wwest (Jul 07, 2008 5:39 am) No I did not do any service yet. What do you think about the cost? Or what should I say to mechanic about the problem? What part of that must be changed or removed?   Sincerely Replies to this message: wwest (Jul 07, 2008 3:12 pm)

Replying to: mohull (Jul 07, 2008 11:48 am) That was my answer to your question...   Take it to Toyota and have it serviced.

Replying to: jimmy22 (Jul 06, 2005 6:20 am) jimmy22   I purchased an off lease 2005 and it is great, have a 1996 XL with 245000 miiles still runs great. Search around on the site, some people mention a TSB that fix a transmission hesitation problem. Also if your check engine light comes on or engine misfires you may want to check replacing the ingnition coils. Friend bought a 2005 touring and had to do this due to engine misfire, his car has 37K   Love my avalons, wife has a 1995 corolla with 167K   mark

#86 of 90 Tranny failure ? by rmg314 Nov 22, 2008 (10:02 am)
Hello all !   I have a 1998 Avalon XLS with 110,000 miles. The problem I am having is with the transmission. It works fine,, shifts fine except when I am starting out from a stop. When I hit the gas, it jumps forward and takes off. Other cars I have owned, it seems like there is a gradual shift into gear without it jerking forward but on this car it feels as if it hits the gear hard and the car jumps forward. I bought the car used last year with 97,000 miles on it so i dont know that much of the car history. I checked the tranny fluid and its clear pink without any unusual odor.   Any thoughts or suggestions would be appreciated.   Thanks, RMG314 Replies to this message: wwest (Nov 22, 2008 10:15 am) wwest (Jan 03, 2009 10:59 am)

Replying to: rmg314 (Nov 22, 2008 10:02 am) If you happen to mean "california stops", not quite coming to a full stop, then for a car with that many miles that might be your problem. Otherwise you're probably driving with a transaxle that will soon need a rebuild.

Replying to: mikes. (Mar 20, 2005 10:54 pm) I have a 2000 XLS with 306,000 miles. All I've done is service it every 90,000 miles when I changed the timing belt. I have had to replace the struts and once the ball bearings, but that's it. The motor and transmission run great and I am told by the oil change folks the oil is as clear as a new car. In fact, I am wondering what failure is most likely to leave me "high and dry" while on the road?   Sim Replies to this message: Mr_Shiftright (Jan 03, 2009 11:18 am)

Replying to: rmg314 (Nov 22, 2008 10:02 am) More modern, say beginning in '98, FWD & F/AWD vehicles DO NOT downshift into 1st gear during lift throttle coastdown periods until/unless the vehicle comes to a full and complete stop. If you happen to try to accelerate just prior to this downshift you will always get a jerky acceleration.   You can somewhat avoid this "feature" via manually downshifting into first as you roll to(ward) a stop, and before gas pedal depression.   Later models use DBW to prevent a rise in engine RPM until the downshift is complete, softening the GO...   You might also want a technician to check for slack in the (cable) coupling from the gas pedal to the throttle butterfly valve.

Replying to: nightlinger (Jan 03, 2009 10:41 am) AAA reports that most breakdowns on the road are due to fairly simple things like bad belts, hoses, blow-outs.   If you've never had radiator renewed or new water pump, you're pushing your luck there. If you've never had a catalytic converter, then it's well beyond its life span.   Also I'd put your car on the lift and have things tightened up and checked for structural issues, like cracks in suspension mounts. Also a good time to check for leaks, including oil, water and exhaust.
