May I ask a Toyota transmission question please?? Dear newsgroup, I wonder if I may ask you, who in your opinion is the most knowledgeable person for me to ask about a Toyota transmission, 1991 Camry please? I gotta wee bit of a problem (actually me mum). Any thoughts you may share with me would be very appreciated and thanks in advance! Most Gratefully, big ed PS Please don't respond to email above. Its unopenable. > May I ask a Toyota transmission question please?? > [quoted text clipped - 8 lines] > > PS Please don't respond to email above. Its unopenable.

He was a Factory Rep for a few years, and knows a lot about Toys. Not only that, he is a really good guy, as you saw from your rapid response! In addition to the motor mounts, it could also be one or both axles, which I may be inclined to believe even more than motor/tranny mounts. There are ways to check both. With the engine running, the Parking brake ON and a FIRM foot on the brake, open the hood and have someone shift the car from neutral to drive and then to reverse. Stand aside the car (not in front!) and watch the engine. If it moves more than an inch or so, or jumps, it's a motor mount. If the tranny moves, check the tranny mounts. Do you hear any kind of rubbing or grinding taking corners? Or a clicking? This would indicate CV joints, about the same as Universal joints on a RWD car. You can lift the car with a jack and grab the wheel and try to turn it with the tranny in park. If you feel a 'notch' or hear a clunk, chances are it's the CV joint. My Supra does this same thing, esp when cold, but I KNOW the universals are shot from having an AT that doesn't shift by itself. I learned how to shift it nice and smooth, the girl before me didn't! :( > e > [quoted text clipped - 21 lines] >> Black Helicopter Repair Services, Ltd.| Official Proof of Purchase >> =========================================================================== > May I ask a Toyota transmission question please?? > [quoted text clipped - 8 lines] > > PS Please don't respond to email above.

Should I drain the tyranny fluid and if so, exactly where is the drain bolt on this model? 91 Camry/4 cylinder/auto trans with overdrive. ed >> If there is no other work done recently or damage you know of to the >> engine mounts, then check the fluid level and the condition of the auto [quoted text clipped - 6 lines] > > ed If the automatic transmission fluid is not red and translucent or you do not know the last time it has been changed, then you should change the ATF. The drain bolt is in the bottom of the transmission fluid pan. SignatureRay O (correct punctuation to reply) The first year of the Lexus ES300 was notorious for their rotten tranny. It had a little plastic ball in it that would wear out and the tranny would start shifting funny and/or making a klunk sound. All you needed to do was take it Hans und Franz at the tranny shop and let them do their mystical $2000 job on it or to the stealership and let them do their $4000 magic to it, and it was good as new. Could be the same problem? The ball was in something where it went up and down with pressure as you shifted from reverse into drive or other such gears. At least they explained it to me that way. It screwed up at about 86,000 miles on the wife's kudzu burner. > >> If there is no other work done recently or damage you know of to the > >> engine mounts, then check the fluid level and the condition of the auto [quoted text clipped - 10 lines] > know the last time it has been changed, then you should change the ATF.

Sorry, yes, ATF = automatic transmissionn fluid. > Also is there a brand or viscosity preference? I do not have a particular brand preference, other than sticking to a name brand. ATF is not packaged and classified by viscosity. ATF has a specific type, for example, your transmission probabaly uses Dexron III - check the dipstick for the correct ATF type. > She's got over 140 thousand miles. > > ed If the ATF is original, I would not have the transmission fluid flushed.

SignatureRay O (correct punctuation to reply) > If the ATF is original, I would not have the transmission fluid flushed. > I would just drain and refill the ATF. Hi Ray, I've heard other people offer up this same advice regarding automatic transmissions with over 100,000 miles on them that contain the original ATF. However, it's been a while since I was given the mechanical reasoning/logic behind this advice. Can you provide myself and the rest of the group with the reasoning behind this suggestion? I do remember something to the effect that a flush at this point could cause internal component damage to some of the transmission's moving components. But again, I just can't remember exactly why. Thanks in advance! Ron M. >> If the ATF is original, I would not have the transmission fluid flushed. >> I would just drain and refill the ATF. [quoted text clipped - 13 lines] > > Ron M. An automatic transmission has internal clutches and bands that are immersed in the automatic transmission fluid (ATF). As the friction material on the clutches wear, it is carried by the ATF and tends to settle in tight passages and at the bottom of the transmission fluid pan as a sludge-like goo. A power flush could dislodge the goo from where it has settled and get it stuck in a tight orifice and cause shifting problems. If the transmission has been flushed routinely, then the goo doesn't have a chance to accumulate, but if there is a chance that there is a goo accumulation, a simple drain and refill is a safer course of action. If you look at the owner's manual, the automaker doesn't even list a transmission flush in the recommended maintenance interval, just a drain and refill. SignatureRay O (correct punctuation to reply) Oh and Ray, The interior light, dash light and electric windows on the right side have conked out. Any advise sir? Thanks in advance and a very happy holiday to you! ed > >> If the ATF is original, I would not have the transmission fluid flushed. > >> I would just drain and refill the ATF.

If the switch is stuck, carefully peel back the rubber boot and spray with WD-40. A happy holiday to you too!

After I read your response, it came back to me what the other guy had stated during a conversation that I had with him a while back. It makes sense. I think the best bet for owners of vehicles with automatic transmissions is to change the ATF every 30,000 miles max. >>>> If the ATF is original, I would not have the transmission fluid >>>> flushed.

SignatureRay O (correct punctuation to reply) I have a 96 Toyota Camry V-6 wagon with automatic transmission, 146,000 miles. It was my parents', meticulously maintained by a Toyota dealership. In the last year, I have had to repair rack and pinion leak and now have a big transmission fluid leak from O-rings on front of transmission. I am going to replace all seals and gaskets on the front of transmission while I'm at it (e.g., seal around pump), but repair person proposed rebuilding entire transmission at same time as proactive repair while the transmission is out. Friction material from clutch wear is evident in pan (do I have that right) although I don't think anything alarming. I need to get another 50,000+ miles out of this car, but rebuilding transmission would double the price of this repair, to about $2300. Is this a wise preventive measure, totally unnecessary, or am I just better off gambling that it will be ok for a long time to come? I need to make this decision by tomorrow morning so please advise. I do not see much on the web to suggest that 96 Camrys have a history of transmission problems. Thanks, Jane > >> If the ATF is original, I would not have the transmission fluid flushed. > >> I would just drain and refill the ATF.

Depending on how the vehicle has been driven, that may be at the end of its useful life without a rebuild. Find out what kind of warranty you get for the $2,300 and how much a remanufactured transmission is. If the warranty is decent and if whoever is doing the work is competent, then you should be able to easily get another 150,000 miles after the rebuild. SignatureRay O (correct punctuation to reply) No expert here, but something you might check. '91 Camrys had various automatics depending on if they were 4 cyl or V6, and depending on the trim level, for example, then top of the line LE had electronically controlled. There is a throttle pressure cable that goes from the throttle body down to the trans. If this is adjusted improperly, or if the throttle is not closing all the way, it can cause very harsh engagement. To check the adjustment, open the throttle all the way and look for a round bead on the transmission cable where it disappears into a rubber sheath near the throttle body end. The ball should be half in and half out of the rubber sleeve at wide open throttle, if it is, do not adjust it. Check for why the throttle may not be closing all the way, for example, gummy build up on it's back side.
