Problem with auto converter isnt locking up

[taslucas]

how did/what did you do to resolve the lockup converter problem?

That's the crazy part.... Nothing I did made any difference..... Reco torque converter, brand new genuine TPS, had the box pulled down for a rebuild and found it was in excellent condition (recently rebuilt) so trans specialist went over everything, every little part looking for a fault and found none. While it was apart I got an aftermarket heavy duty valvebody fitted. Brand new genuine temp sender, replaced torque converter main shaft seal, had the tcu out and inspected. Checked all wiring looms, checked fuses.
Still the same problem.

Then one day it just went away!!!!!!!

Didnt know whether to be happy or sad! Happy the problem was gone, sad that I spent so much money on things I didnt have to.

That was nearly a year ago and the problem hadn't come back!!!

Tap, crackle, pop

Going to change tranny fluid again this week end, both nissan and tranny specialist said castrol dextron 3 is fine, will replace filter this time, and not put nulon additive in as the tranny guy said it was too slippery in his opinion for an auto locking converter, he said if needed use wynns or something just not nulon... see if it starts locking up again like it was before I replaced fluid last weekend and added nulon..

how many fuses are there to check?

I find it odd you didnt chnage the filter when changing the oil. This would be the first thing to do. Oil is cheap and so are filters if the filters clogged changing oil and putting in additives isnt gonna do much.

Wasnt aware there was one When I changed the fluid as my manual does not mention one so I didnt change any filter, couldnt see one and for that matter wouldnt know what it looks like, tranny sump was clean, just build up of powdery stuff on the magnet, no filings or bits of rubber in the sump...

You should still have a tiny bit of fillings, just the way they are. The rubber as you say, that doesnt seem right to me, im sure someone will shed some light on this.

There was the usual metal powdery stuff stuck to the magnet, but no chunks of metal or shards thats what i mean by "no filings or bits of rubber in the sump" as in apart from what was stuck to the magnet, the sump was clean...

How much metal powder stuck to the magnet,??? In my pics you will see how much was stuck to my magnet. No chunks, but one set of clutch packs was completely worn
