Question QUESTION: Hi Roland,
I'm the guy who has the 2002 Chrysler t&c who had the trans stuck in "limp in mode"and told you the codes were p0700,and p0605,well i bought a refurbished tcm from auto computer exchange and replaced the out put speed sensor,you ask me to write back when i got the module in,so here i am put the module in and the car is still in limp in mode,although the check engine light is off now,im so frustrated with this thing,the company asked me the mileage and Vin and year so they could program it there,is there something else i need to do??????i thought for sure i had it fixed but it still wont go out of limp in mode,please help,.....
ANSWER: Hi Eric,
Have you tried disconnecting the battery to erase the old codes, then reconnecting to see if there is a new/different code? I'll check the trans manual and see if any other programming is needed, and if so send you a follow-up.

PS: Have you checked the trans fluid level?
It is possible that a procedure called the "quick learn" has to be done by a dealer using a DRB III plug-in device. One thing you might try before doing that is to by pass the transmission relay in the power distribution box under the hood, and that will abort the limp-in (which was originally accomplished by 'opening' that relay). You would remove the relay, 2nd from the front on the driver edge of the box, and then jump a wire from the rear inboard pin (30) to the front outboard pin (87) of the the relay socket. Then try driving and see if it behaves reasonably. The trans controller will 'learn' the characteristics of the trans as you go thru the gears and slow down for a dozen or so times. Then put the relay back in after removing the jumper.
Those are some ideas to consider. Please let me know.

QUESTION: O.K. when i did the ignition check p1684 showed,and i noticed that on the dash where P R N D 3 1 is now those are circled by a square around them,when before they were not.and my speedometer is not working again.That is what i see,but the check engine light is off.
Answer Hi Eric,
The 1684 is just the result of disconnecting the battery, so that is expected. The speedo not working is relevant because that will cause a limp-in in most cases. Check the plug on the output speed sensor again. Another code for the output speed sensor should show up soon when you check for codes if the speedo doesn't come back.
Did you notice my PS?
