I just had my 3600/2.2 TC installed in my TA. I am having a couple of problems. First, I am getting a grinding noise when the car hits 40 and goes into OD. It is like gears grinding. From what I have read it might be the TC cluch.
Second is I keep getting error 0757(Shift Solenoid Sticking). When the SES light comes on for this code I lose 1st gear. I reset the code and everything is fine.
Can anyone help explain these problems or help remedy them.
Thanks in advance

If the TC clutch is being applied through the 3-4 shift
you might hear a yelp. The clutch -should- engage
quietly but you want to have a good ATF that has
anti-chatter additives. I think you'll want to alter the
TCC lock/unlock points to suit the converter better.
Though 38 is where I currently run my 4th lockup at
very low pedal, same 3.42s. The grind /squeal sounds
kind of like what I got off my TCI when I had the wrong
fluid in it, the clutch would chatter on soft applies or
light slip. Proper fluid just made it slip quieter. The low
available line pressure at light cruise means the clutch
is pretty much guaranteed to slip on these cars. But
some more than others, and small diameter converters
just have a harder time holding anyway (torque being
radius*line pressure*friction more or less).

The TCC apply chatter on my car sounds like a bird
squawk.

Don't know about the shift solenoid code. The only
code I ever got off my TCI has been "transmission
component slipping" from the weak clutch. Might pull &
reseat the big trans control harness connector and
check that nobody munged the pins, etc. If there was
any inside-the-pan work done you might want to look
inside too, internal connectors / pinched wires etc.
The trans operation is funny about codes, it will just
quit trying when one gets set (like with my tranny slip
code it would just not apply the TCC anymore).

It took about 400 miles of driving for my TCI's clutch
problems to develop fully, after install. If it starts getting
better, chalk it up to bedding-in. If it keeps getting worse
then ???

Hopefully it isn't something dumb (but not uncommon) like
only seating the TC in by two clunks instead of 3 and not
having the pump fully engaged. That would suck. But that
would make more pervasive problems than you're seeing,
I think.

What fluid would you recommend. Pennzoil Mult-Vehicle synthetic was used. It says it is good for our cars.

Hopefully Fuddle will chime in here but my take is,
any converter maked -knows- they have to play nice
with straight formula DexronIII but Type F (my B&M
problem) or synthetics, that's questionable. The GM
TCC I believe is an organic clutch material, my TCI
is some sort of carbon, my Fuddle converter in the box
is supposed to have been built with a "nodular carbon"
clutch that's somehow better. But these different
clutch materials systems may or may not have ever
been tested by Pennzoil or by Fuddle / Torque Converter
Company for anti-chatter or plain old load holding.

Might want to go by the DayGloAutoPartz store and
look at the label, see if it's proud to say "meets newest
GM anti-chatter specs" or words to that effect. If the
OD noise is like I described I think that's the deal and
personally I'd get the synthetic out and the dinosaur
in, before much more driving. But I'm paranoid, having
been bit once by "better than OEM" tranny juice being
not-better on non-OEM materials.

You might email Fuddle for their take on this and maybe
get any info you can on the clutch material type in yours,
and talk to Pennzoil applications folks (if you can find a
contact) about what (if anything) they know about the
specific compatibility.

I know I emailed TCI about the B&M juice before install,
they said they had no idea and couldn't recommend it,
I let it go in anyway on the mechanic's (Old Skool) rec'
and the rest (along with my clutch) is history. So, the
$80 or so for a total power-flush at the Valvoline place
might be well spent (before bad gets to any worse).

Anyway, see what the research gets you and if it's all
the e-equivalent of a dumb look then I'd get its stomach
pumped and try some "natural" juice with good words on
the label. I've been using the Castrol but I think Valvoline
is OK too. Be sure to look for the anti-chatter info but see if
Fuddle can tell you anything about recommended brands.

Im starting to lean to the fluids. I was reading up on the code issue and I did fix the problem by driving around in third. Third is drive in the TA and D is OD if Im not mistaken. I guess I will have to just suffer the gas mileage until I get the code deleted for good. I need to find someone around Pittsburgh who can delete it for me. Is it OK to shift into D once I get around 55 on the highway and then to 3 when I get off the hwy?

Here is a link to the fluid. Doesnt say anything about chatter but does say its compatible. Whether its compatible to Fuddle converters is the next question to be answered.

Would it be worth doing a regular fluid change without taking the TC out to get all the fluids out of it?

I have had the exact same problems with mine(Fuddle 3400 1.8 STR). I didn't start getting the P0757 until I installed the Trans-go shift kit. Do you have one installed?

My converter also shuddered on lockup, My car was also throwing missfire codes from the converter too. I have adjusted my lockup points, adjusted a few tables in HP tuners to make the lockup solid and disabled the missfire tables. No problems since.....

The P0757, I always got that code thrown when I would be driving say at 40mph and somebody would slow down infront of me(say to turn) The car would be in 3rd or 4th gear, and as I would lean into the throttle to accellerate, it would down shift into 2nd gear, thats when it would throw the code. My guess is the PCM is seeing more RPM(because of the stall) than it thinks it should, therefore thinking the tranny is slipping, throwing the code. Anyway long story short, I just disabled this DTC with HP tuners and have had no problems since.

MNR-0

Correct. There is an upper boundary set within the ECM that monitors converter slip RPM. If it exceeds so many RPM it will trigger the code. Again, this is normal for smaller diameter converters due to reduced rotating inertias and less fluid flow. Either raise the limits or disable the code. Misfire codes are also a common problem and related to the same cause.

Converters can be fiddly but get the program right and its performance city.

How hard is HP Tuners to learn. I need to get some of this software. Would changing the TC lockup points be a hard thing to do for a beginner?
Thanks for all the help!
I cant wait to get this resolved.

Maybe try the "midwest forum" or where ever Pittsburgh is in (northeast?). And see if anyone has the HPtuner in that area for your year model. Im sure someone does. Then you guys can hook up and delete it for ya.
I got a bud here in MN with one for his 99 so he "tweaks" my TA as well.

Just a thought.

MNR-0

Not hard. Just time consuming. But for what you want to do - too easy.

put the fuddle in and now when in reverse i get lockup and MAJOR grinding and when i start driving it locks up at like 15mph i have it tuned for 38 mph lockup the same tune on my buddies car is perfect. WTF!?? im getting major lockup problem.s

94bamf

Is the converter the only thing installed, or did you install a shift kit, or did you change your tune? How many miles on the car? Did you install a new Teflon Seal on the stator shaft?

chummmma

iTrader: (8)

trans was rebuilt was fine for 200 miles car has 59000 miles and i just updated the tune with a custom converter tune.

I have talked to onyx_rock on the phone and we have what hopefully will be a mechanical remedy ready to ship first thing Monday. I'm sure he will keep you updated about the situation.

Chummmma,
When did the converter start having the problems? Was it happening before your transmission went out?

chummmma

iTrader: (8)

no the transmission just went in and it waas fine with the stock stall then with the new stall i got like 300-400 miles and problems started happening im gonna try the TCC lockup solenoid ill keep you informed.

Save your money, you have a converter problem.

PM sent. If it is a converter problem, of course we'll replace it immedeatly.
