my 97 max through out p0600, p0500,p0325. i was reading around and saw how TCM(p0600) could give out the rest of the codes. the car runs good and shifts great and my speedo works good. im taking it to an electrician i trust but just wanted to get some more opinions. i read how if the TCM is bad it could cause damage. any advice? thx in advance.


*update*
i took it in a transmission/repair shop that my electrician recommended and the guy saw how my transmission shifts fine with no slip, how my speedometer works and how my transmission is not in limp mode. he said that he dont believe it anything major bc it runs fine. he suggested to swap out my A/T control unit with my other 96max(which i gave my dad after i bought this one) and see if i gets codes still and after that the ECM. Like i just got the max the machanic nor i know if the ECM or the A/T control unit was ever replace with a bad/mismatch one. the cruse control works too so dont think the VSS is bad. could a bad VSS trip a TCM code? bc i read here that a bad TCM could trip a VSS code. another thing, r all the the none LSD tranny the same on the 4th gen max? any advice?

*Update 2 and final (i hope)*

Well I took the speedo off and tighten the screws in the back. I cleared codes and after 1 week still no codes so i think i took care of it. Just wanted to post this for any1 else that has this problem can try this and see if it works.

 

Ty for advice but i believe it to be wrong. p0325 is knock sensor and we all know how our max love to trip the code with other ones and i have read no were how a KS has anything to do directly with tranny. p0500 is VSS and yes its hook up with to tranny but a bad VSS is a far cry from a bad tranny, especially mine that shifts fine and not in limp mode either nor slipping. p0600 is the TCM but again thats does not mean a bad tranny, if tanny was in limp mode then it would be bad, but the tranny it self would most like not be. Any1 new here that dont know better would crap his pants if u told him to get a new tranny bc no1 wants to pay for a tranny. i know u r trying to help and im not trying to be mean so dont take it that way, just trying to explain why i think ur advice is wrong, nothing personal.

 

have you tried re-setting the CEL?

 

at the shop he reset the codes and after 5-6hrs driving off and on it came back on. I have a actron 9175 coming so I'll clean the speedo connection from the back and reset and see what happens. My O/D light flash 5-6 times sometimes after I turn it on. I'm guessing its something weird/simple bc everything seems to work fine.

 

If you think its your tranny, and its automatic, heres how you can check it for codes:
1. Turn to ON, but dont start it
2. Move to Drive
3. Turn OFF
4. Put O/D OFF
5. Turn ON, wait 2 sec's, shift to 2
6. Put O/D ON
7. Shift to 1
8. Turn O/D OFF
9. Press gas to the floor, then the CEL will flash giving you tranny codes.
If you get any codes doing this and dont know what it is pm me, and Ill tell you.

 

I should get my OBDII scanner this week and ill do this, i saw this on the stickies yesturday and was going to do it once i get scanner. im tired of going to autozone hahah. the more i read the more i believe its my speedo connection or the speedo itself. but ty for the advice and ill get back to u and post my results as soon as i can.

 

To do this, you dont need an OBDII, just your keys and car. This brings up your transmission codes, not your CEL codes.

 

Well im guessing my guess was right, 1st was a long flash and the other 9 was short and on the stickie it said that should be the Revolution sensor is shorted or disconnected. Correct me if im wrong. I feel like a weight was off my shoulder bc i would hate it to be a tranny problem. If im right, ill just take out my speedo and clean and tighten connections, clear CEL and if it comes back, and if it does ill see if i can buy a cluster that has 130k miles bc dont want to pay dealer for them to do it and dont want false miles on my car even tho i might keep this car until i can get a WRX which might be awhile

*edit*
Well after thinking for a bit ill clean and reconnect speedo, and if still gives codes ill do the VSS even tho it seems to be working just fine but its alot cheaper then the whole cluster replacment and i guess i can gamble. If any1 has a better idea plz tell me.
