Ok, I have found it. It is the part with the mounting brackets (2 nuts + 1 bolt). According to the TSB, the faulty part number is 31036-4W000 which corresponds to my part number. It seems I have found my problem. Thank you again for the diagram and for the TSB Service Bulletins Nissan Cars (I can't remember who lead me in that direction.

Probably save me a few grand as the mechanic wanted to replace both my catalytic convertors at a total cost of $2100 cdn + tax. I have now replace all my ignition coils and I will now work on my TCM replacement.

All ignition coils have now been replaced. TCM is replaced and all is running ok. CEL is still on but it is running great.

Thanks again for the diagram

Ok, now I just have transmission flaring in very cold weather. I would like to replace the Solenoid Assy-Control (31940-41X15). Has anyone performed this procedure? The price is cheap at $45. Cdn$. I asked Nissan and they said it would take 5 hrs or around $500 in labour plus the cost of the part. Any suggestions or help would be greatly appreciated. If a non-mechanic type shouldn't be doing it, than I live in Brampton, Ontario area.

Thanks

Are you saying you had the TCM replaced first, and now have transmission flaring in very cold weather so you are looking to replace the solenoid?

I have just begun to experience this issue. Oddly enough just spent $150 on a tranny flush with Nissan fluids. I have the 2-3 flare, very slight, and goes away after the first 3 tranny cycles in the morning, then fine all day. I have all-mode, will it make a difference if I put it in auto 4 or 4wd high?

Assuming the solenoid is in the tranny? What will a new TCM & solenoid cost? And labour?

Thanks

I think I am having this problem also. Any pictures of the TCM under the dash. I have seen the schematics. Do you need to remove some other device to gain access to TCM? Thanks.

OK, my VIN# does not fall in the parameters of this service bulletin. However, the truck was built before April 20, 2000. I looked and found the actual TCM. Does anyone know where the part # is located? Or, do I need to remove the unit to find it? Also, if my truck does have part # 31036-4W000. Is it an easy switch with the newer part # 31036-4W001? Or, does something need to be reprogrammed by dealer or code reader? Thanks in advance.

Hi, I recently bought part# 31036 - 4W001 or TCM. Once installed, does the car just acknowledge the new part? Or does something need to be reprogrammed by my independent mechanic or a dealer? THANKS.

Update, changed out my TCM yesterday. It was pretty easy. Took about 10 minutes. 3 bolts and two plugs. Transmission is working great now. Dealer wanted $619 for the part. I found one at a junkyard for $77 shipped.
