Trans Solenoid pack bad after TCM change?
 
Hi,

so first of all, I have to say I am impressed by the forum. I had some issues with my PT Cruiser (2002, touring, automatic) and usually this forum had all the information that I needed. That was pretty impressive and really helpful!

I now searched a bit, but did not find a specific answer for my current problem (why is there always something wrong with the car?....):

A couple of weeks a ago I changed the TCM module (had the errorcode p0605). Check engine light went away and no error codes are present in the car. However, sometimes now the shift into the first gear is rough and the car does shake a little. It does not happen all the time and I could not find a pattern. This started right after I changed the TCM. Right after there were a couple of more violent shifts and I think they were bit more frequent. Prior to that I never had issues with shifting gears.

As I bought the TCM from carcomputerexchange, I asked them, and they said that I should change the solenoid pack for the transmission. I am now a little bit skeptical as this really could be the issue. In particular given that it shifted fine before the TCM went bad.

Any opinions? Would this be a logical step to do or is it more likely that the TCM is not working 100% properly?

Any advice/thoughts would be really great!
Thanks,
Thomas

If your were generalizing and not personalizing your mechanical condition, not everybody has problems with their PT's, all the time!:p



The solenoid pack is mostly likely not been updated and if you have not regularly changed out the fluid and filter there may be a varnish on the solenoids which is causing them to stick. IMO take the advise of the experts and change out the pack and while you are there the fluid and filter.:D


WELCOME TO THE FORUM:cool:

Yes yes, not wanna go into detail of my late PTC issues...:mad:

Well, the reason I am not trusting the "experts" so much in that case (well don't trust them in general, but that is another issue:p) is that they have an interest that they do not have to replace the TCM again, so I suppose they will try to convince me that everything but the TCM is bad. Well, but maybe they are right.

On a related note - I am going for a trip on the weekend, will be ~600 miles, I guess I still could risk it driving? I got stuck once now with a broken car, not really keen to redo that....

Thanks, for the welcome, you are the best :D

You assumed when I said "expert" I was referring to the shop you purchased you TCM from! ;) :laugh:

IMO I would at least change your fluid and filter before adding to many more miles on a questionable mechanical condition.. It is easy enough to do and semi inexpensive. You may also want to get a bottle of fluid conditioner as well?

hehe, well that was the only one that might have been close to something like an expert, hence....:p

Currently, I am not sure if my Cruiser will ever make it out of the state of 'questionable mechanical condition'....

How much would that change roughly be?

Read the following instructions in section #6 below---twice. Did you or they follow these procedures correctly? If not you may have started the replacement procedure using a "good" TCM to replace the apparently "bad" one, but you probably didn't finish with one.

A "flush" of your transmission with a filter change by a place with a flushing machine runs about $200 - be sure that all that is used is ATF + 4.

Some people should continue to learn about new things and not settle for what they once knew as absolute! :rolleyes:

PLEASE NOTE!


This module is PLUG-and-PLAY. No Need To Visit the Dealer! Comes With 1 Year Warranty!

Many ecu, tcm, pcm, etc., from re-builders have the ability to load the appropriate information into the units so the need to go to a dealer and spend more money not necessary.

^^Don this is good info and generally I would also recommend it but in this case I sense the need for inexpensive and something that easily and affordable be accomplished now?:cool:

To be taken into consideration it is not necessary get a transmission flushed unless you have discolored fluid or during the filter change find unusual amounts of copper or aluminum in the pan.
A simple 45 minute DIY driveway transmission service will generally do the trick.

Not quite what your point is, but I had the correctly programmed one, so I guess it should be fine. Apart from that I followed the instructions, I guess there is not much you can do wrong there....

I checked the tranny fluid and this seems pretty clean, no dirt and fully transparent....
So transmission fluid change and I'll also order the solenoids, seems also a thing you can do yourself.

I thought my point was very clear----It's very possable to inadvertently damage the TCM itself if the installer doesn't follow proper precautions when installing the unit. That was the section imediately following the #6 that had the large arrow pointing to it and starts with the word ---CAUTION---. I would have thought that would be hard to miss. Mental note to self--use larger arrows.

IF you followed the instructions then you should be fine.
