harsh shifting, early or late shifing? ALL 1990

Sorry, I am not a volov owner, I have a 90 Camry V6 with A/T. My car

has trouble when it shifts from 1 to 2. I searched on the internet,

somewhere in this board, someone had the same problme before.

Let me start with what the problem is: I feel the car shifts from

1 to 2 is not smooth, very rough. other up-shifting and down-shiftings

are just fine, not matter if the engine is hot or cold. I also noticed

there is something abnormal of the speed meter. When the 1-2 up shifting

happens, the speed meter needle points to zero, certainly, the real

vehicle speed is not zero. after the 1-2 shifting happens, the speed

meter needle just goes up like normal. is this correct or is this normal

for a camry? I notice my friend's prelude (A/T), when his needle points

to about 15KM/hour, then the 1-2 upshifting happens.

as I said before, I found there are some articles talking about

1-2 harsh shifting in this board. mostly like something wrong

with the check ball inside the valve body, or bad accumlator spring or

by adjusting thortte cable. So, I took my car to two AAMCO transmission

dealership in Toronto. after they checked the vehicle, the first

dealership told me, if I spend $300-$600 CADs, they can fix it, then

I asked them to do it. guess what? they did what they suspect,

but the problem is still there! anyway, they did charge me anything,

and told me if I spend $1500 canadian dollars, they guarantee to

fix it. The car is 11 years old, I just don't want to speed too much

money on that. So I went away. This morning, I took my car to the

second AAMCO transmission dealership, tell them what the problem is,

and tell them what I suspect as well as what I found on the internet,

damn, he just didn't listen to me, when I said I also notice something

not correct with the speed meter, he responsed: "The internet didn't tell

you this?". anyway, anothe guy checked my car, and said the transmission

need to be rebuild, which will cost $1900 candian dollars plus other parts!

then I told this guy is the valve body ok? is the spring ok? he said

he tried to adjust shift timing, it didn't work. so he said the problem

is not the check ball nor the spring, coz when he change the shift timing,

the shift points should change, but they didn't change. do you guys think

this is correct? BTW, he said he changed the shift timing, when I drove

back my car to work this morning, I noticed the 1-2 up shifting is little

bit smoother than before, also other up shiftings are kind of late, but that's

my feeling, I am not so sure about that.

I wonder can I adjust shifting timing by myself? Can I check my speed sensor

by myself? anything else I can do before I send my car to another garage to

repaire?

AAMCO gave me a bad impression, because I have went to the second AAMCO

transmission garage two weeks ago, after a short road test, the guy told

me nothing wrong with the transmission...then after two weeks, I sent my

car to them again, they said I need to rebuild my tranny for $1900+ to fix

the problem...Damn, are they specialists? I will never trust AAMCO again

especially the one on 2941 Eglinton.

BTW, I did a simple road test according to Tony's suggestion in this board:

put gear in "L", drive it to 20km/h, then shift the gear to "2", I feel the

shock.

any suggestions are welcomed!

BTW, any of you guys from Toronto? can you suggest somewhere I can go to fix

my tranny? It's too difficult to tell the mechanic what I think the problem

is, they just don't want to listen to you.

Thanks!
