Coester,
 
I bought a 2000 Avalon XLS which I purchased at 60,009. After driving 615 miles, my check engine light (CEL)came on...no codes stored...but for some reason dealership check code #0773. It was not my gas cap!! Drove the car 1,948 miles, CEL came on with code #0773. Dealership replaced the transmission under my extra care warranty. Drove the car 15,908, CEL comes back on with code #0773..dealership replaced vehicle speed sensor. Now at 89,000 CEL is back on with code #0773 and code #0171 (air flow sensor). Extra care warranty is expired and now they want to replace
Engine Control Module at the cost of $1283 (pts/labor) and the air flow sensor at $251 (pts/labor)..plus its time for a transmission flushing for$169.95 for a total cost of $1705.95. After reading all the postings on the AT in Avalons, I wonder if cars owners could start a campaign to get Toyota to recall whatever is causing so many people to experience transmssion problems so early in the life of avalons or any other toyota products. Toyota boast such reliable cars. :lemons??:

Just so you know here are the definitions of your check engine codes.
 
P0773 Generic Shift Solenoid E Electrical
P0171 Generic System Too Lean (Bank 1)
 
Perhaps its time to talk to your dealer. There are many things that can case a System Too Lean. I'd look towards the O2 sensors or mass airflow sensor.
 
Hope that helps,

PS - Here is a link to a code look up data base just select Toyota and enter P before your codes p0171, etc.

2000 XL Tranny Question by dave128
Mar 06, 2007 (2:27 pm)
Reply
Original owner, 116K miles, AT fluid changed each 30K. Recently noticed a minor reddish leak under the engine and the dealer checked it and said the front transmission pump seal was leaking. Cost would be about $900 to replace that seal the the rear main one. I'm inclined to just use some Valvoline ATF Sealant and ride it out. Anyone else have this issue? Also, where's the AT fluid fill located at?

Take it to someone else. Overpriced. Way overpriced. Yes, the power steering uses same TypeIII fluid as the tranny in our model. Fluid resevoir on the passenger side of the engine bay nearer to the R wheel well. Black colored cap, easy to access. After repairs are made, changing the tranny fluid and the PS fluid(relatively easy to do) at the same time is a good idea in this car.

2003 Avalon XLS Check Engine Light after Transmission Fluid Change by bettesue
Mar 18, 2007 (5:14 am)

Two questions:
 
(1) At 63,000 miles I changed the transmission filter and fluid. Unfortunately, the check engine light and VSC lights came on with an error code of P2735, Pressure control solenoid Electrical (if I remember correctly). Toyota Dealer couldn't find anything wrong just using the scanner. Would have to charge to drop transmission pan to view - be prepared to replace a valve at a cost of $166 + 2 hours labor. Car runs great; no burning smell in fluid; proper fluid levels.
 
(2) One neighbor, a former Toyota mechanic, recommended I buy the service manuals since I plan to keep my car for 200,000+ miles. Should have asked which one(s). Recommendations?

I have the speficif service manuals (toyota) for my 02. I usually buy them for every vehicle I own, as I also usually keep them for over 200K. The Avalon is a 2 volume set, although now I am sure it is avail on CD-ROM. I always find the service manauals handy, enabling me to either do it myself, or at least talk the talk to the service manageer or whoever. I remembe them being around $200 for the set. There is a Haynes manual but more generic. Not of them are totally comprehensive, but I always seem to get my money's worth from them. Some of the pages are dirty and greasy, indicating they were used well.
 
I have change my ATF three times, twice with a filter. I only have an XL, but no error codes ever came on anywhere.

I would first try disconnecting and reconnect, reseat, the external electrical connector to those transaxle solenoids.

Third replacement transmission on 99 Avalon by carabed
Apr 15, 2007 (7:45 am)
Reply
My wife's 1999 Avalon XL has had all transmission servicing recommended by Toyota dealer and our dependable local mechanic. We replaced the transmission for the FIRST time at 69k miles with a Toyota rebuilt transmission. Ten months later at 79k a SECOND Toyota rebuilt transmission was installed because of rough, jarring shifts and unusual grinding. It did not work properly (same problems) and after 300 miles was replaced with a THIRD Toyota rebuilt tran. We've only had it one day but the problem still seems to be there The local dealer has been interacting with Toyota engineers to solve the problem but "Toyota transmission problems are so uncommon that they don't have a solution yet."
Any suggestions on how we might get the company to really help fix this problem? Or, is this a lost cause?

Well you might try having the dealer install the next toyota rebuilt transmission. Being both out of warranty and having the work done by an independent mechanic weakens your link to factory assistance two-fold I think.
 
Something isn't right here---either the installation is wrong, or the source of the "rebuilts" is dubious.
 
If you can swing it, wipe the slate clean....ask for a rebuilt from Toyota (not yours rebuilt by a local subcontractor of the dealer) and have the dealer install it. That way, you get the unit's warranty and the dealer's labor warranty.
 
They are either building it wrong or installing it wrong.
