About a month and a half ago I got my tranny replaced with a 96 Tranny (I have a 95 car)...I know there was a lot of talk that this couldn't be done for whatever reason (didn't line up or computer differences).

Anyway, after it being replaced I keep getting a reoccuring code (3-2-3 which is tranny lock up or slip)...the tranny doesn't shift any different then my old tranny (when it was good) and I didn't have any codes then.

My mechanic has suggested it was the automatic shift cable so he replaced that and then he suggested it's probably the neutral lock switch in the console? Would this cause a code like 3-2-3?

Also any other symptons that cause 3-2-3? It also only seems to throw the code when I go at fast speeds, I never seem to get the code when going at slower speeds.

Any suggestions or ideas would be great.

Thanks,

Jay

transmission flush needed?

Well it's a new tranny with fresh fluid in it...so I don't think that's it.

What you have is a gear ratio confliction with the ECM ...I know that some vehicles can have this problem fixed by flashin the ECM...I don't know if it's ever been done on a Volvo though....I'm sure it can be done!

Well seeing how it's from a later model car (96) and things did change computer wise and transmission wise...

If i were to go with a 96 ECU and TCU do you think this would solve the problem? And if I did do this what advantages would I be losing or gaining? Thanks,

This morning colder than normal...I didn't wait much to let the car warm up and I just started to drive...usually on these cold mornings it seems the tranny has a difficult time shifting for whatever reason? So low and behold it had a difficult time shifting into second and once it did it threw a "3-2-2 incorrect gear ratio" is this a result to my ecu difference? (I think it is...but this is the first time I actually threw his code)

Once again...you need to have your ECM flashed...perhaps IPD can help you out...call them and ask?

[jroot]

Just an update...I tried a 1996 ECU and the code came back again.

I also tried putting the 1996 TCU with it as well and that threw a different code.

So I'm just going to take it to a volvo dealer and ask about it there..

[jroot]

Didn't get much positive feedback from them...as they never replace a 1995 tranny with a 1996 tranny.

The guy did mention that it could be the gear position sensor or something like that...sits on top of the tranny?

Maybe this is why my mechanic said 96 and up on a 850 transmission would not work out...

[jroot]

Probably. Although I did notice it shifted better when I had the 96 ECU in..

If you still have the 95 transmission, try cleaning up the pnp and replacing it with the one on the car now. The pnp has been known to cause the 322 code.

The tranny that has the codes is the 1996... (95 died)

But I think I'm going to try doing the PNP switch..

Just wondering if you kept the 95 for parts...just saw your other post...and I'm betting your pnp is bad...fcpgroton sells an aftermarket for cheap.

Oh, well nope I didn't. Although I'm still curious about the speed relating to throwing the code? Have you heard of that?

I think I'm gonna try the PNP, might as well since even the Volvo dealer suggested it too.

Never heard of the speed correlation...though it may just need the same amount of time to throw the code as it takes you to get to highway speeds...good luck.
