Re: clanking sound that driving me nuts.
I flushed mine a week or so ago and no change at all, still clanks, I am not
as freaked as I was when the sound 1st started though, I almost don't notice
it anymore in the city, on the trails it is totaly embarrassing though. Like
I said earlier I beat the poor girl off road with stock gears mud tires a
lift with about 100K since the rebuild and she still keeps on keepin' on, I
guess I will worry about it once it duz finaly die. Been looking around the
bone yards for a sorta cheap emergancy replacement in case it takes a quick
dump on me with no warning, it's my daily driver so have nothing to fall
back on..

Re: clanking sound that driving me nuts. [news]
Last Saturday, I took my car to Cottman in Metuchen, NJ and asked them
to check my radiator on the theory that it is not providing enough
cooling to the tranny. He checked and said it was fine and he was able
to duplicate the clanking by power braking, stepping on the gas and
brake at the same time. He said to take it to Cottman in Freehold, NJ
and tell them it could be the torque converter or flywheel and if they
have any question to call him.
Well, I took it to freehold and the owner was there and he heard it, he
was like okay, it could be the torque converter but I am not a
mechanic, I'd have to have my guy look at it.
I dropped of the car yesterday and called him and he was like, hey, the
sound went away, isn't that great? I told him, dude, if you just turn
it on, leave it in park, it is not going to make the sound, period. he
said he has his tech guy drove around the block, no sound. I was
pissed. So this morning, I took it for a long drive, and did a few
power brake, and sure enough, it was clanking, took it there, told them
bring everyone out, i want you, your uncle, your grandpa to hear it.i
don't want them to tell me oh i heard it but my friend pete's who know
more about tranny than me needs to hear it but he's not there now. i
know if the tranny cools down, it wont make the same sound and i can't
just keep taking days off from work. they said it might be the dust
cover or some lose bolt but they'll work on it. final freakinly man!!
when they take your money, it's all good but when there's time to honor
the warranty, why do i have to be the one doing all the work!

Re: clanking sound that driving me nuts. [news]
Last Saturday, I took my car to Cottman in Metuchen, NJ and asked them
to check my radiator on the theory that it is not providing enough
cooling to the tranny. He checked and said it was fine and he was able
to duplicate the clanking by power braking, stepping on the gas and
brake at the same time. He said to take it to Cottman in Freehold, NJ
and tell them it could be the torque converter or flywheel and if they
have any question to call him.
Well, I took it to freehold and the owner was there and he heard it, he
was like okay, it could be the torque converter but I am not a
mechanic, I'd have to have my guy look at it.
I dropped of the car yesterday and called him and he was like, hey, the
sound went away, isn't that great? I told him, dude, if you just turn
it on, leave it in park, it is not going to make the sound, period. he
said he has his tech guy drove around the block, no sound. I was
pissed. So this morning, I took it for a long drive, and did a few
power brake, and sure enough, it was clanking, took it there, told them
bring everyone out, i want you, your uncle, your grandpa to hear it.i
don't want them to tell me oh i heard it but my friend pete's who know
more about tranny than me needs to hear it but he's not there now. i
know if the tranny cools down, it wont make the same sound and i can't
just keep taking days off from work. they said it might be the dust
cover or some lose bolt but they'll work on it. final freakinly man!!
when they take your money, it's all good but when there's time to honor
the warranty, why do i have to be the one doing all the work!

to check my radiator on the theory that it is not providing enough
cooling to the tranny. He checked and said it was fine and he was able
to duplicate the clanking by power braking, stepping on the gas and
brake at the same time. He said to take it to Cottman in Freehold, NJ
and tell them it could be the torque converter or flywheel and if they
have any question to call him.
Well, I took it to freehold and the owner was there and he heard it, he
was like okay, it could be the torque converter but I am not a
mechanic, I'd have to have my guy look at it.
I dropped of the car yesterday and called him and he was like, hey, the
sound went away, isn't that great? I told him, dude, if you just turn
it on, leave it in park, it is not going to make the sound, period. he
said he has his tech guy drove around the block, no sound. I was
pissed. So this morning, I took it for a long drive, and did a few
power brake, and sure enough, it was clanking, took it there, told them
bring everyone out, i want you, your uncle, your grandpa to hear it.i
don't want them to tell me oh i heard it but my friend pete's who know
more about tranny than me needs to hear it but he's not there now. i
know if the tranny cools down, it wont make the same sound and i can't
just keep taking days off from work. they said it might be the dust
cover or some lose bolt but they'll work on it. final freakinly man!!
when they take your money, it's all good but when there's time to honor
the warranty, why do i have to be the one doing all the work!

to duplicate the clanking by power braking, stepping on the gas and
brake at the same time. He said to take it to Cottman in Freehold, NJ

Re: clanking sound that driving me nuts.
Hi gang:
Last Saturday, I took my car to Cottman in Metuchen, NJ and asked them
to check my radiator on the theory that it is not providing enough
cooling to the tranny. He checked and said it was fine and he was able
to duplicate the clanking by power braking, stepping on the gas and
brake at the same time. He said to take it to Cottman in Freehold, NJ
and tell them it could be the torque converter or flywheel and if they
have any question to call him.
Well, I took it to freehold and the owner was there and he heard it, he
was like okay, it could be the torque converter but I am not a
mechanic, I'd have to have my guy look at it.
I dropped of the car yesterday and called him and he was like, hey, the
sound went away, isn't that great? I told him, dude, if you just turn
it on, leave it in park, it is not going to make the sound, period. he
said he has his tech guy drove around the block, no sound. I was
pissed. So this morning, I took it for a long drive, and did a few
power brake, and sure enough, it was clanking, took it there, told them
bring everyone out, i want you, your uncle, your grandpa to hear it.i
don't want them to tell me oh i heard it but my friend pete's who know
more about tranny than me needs to hear it but he's not there now. i
know if the tranny cools down, it wont make the same sound and i can't
just keep taking days off from work. they said it might be the dust
cover or some lose bolt but they'll work on it. final freakinly man!!
when they take your money, it's all good but when there's time to honor
the warranty, why do i have to be the one doing all the work!
