Trans Failsafe Prog E53 3.0D

[bornonmarch]

Hi everyone

I'm new here. I have 2004 E53 3.0D with GA6HP26Z transmission. I bought it last December when the odo was 220,500 kms and now it has 223,300 kms. We didn't use it very often due to error message.

A week after we purchased it, the car threw Trans Failsafe Prog (TFP) error randomly. And now it happens every time once the temp below a quarter mark!

What I have done to fix these are:
1. new battery with a higher CCA as the starter motor failed (later I found out my previous battery is still good and only needs a re-charging). I also replaced the starter motor with a used one.
2. Previous owner did the transmission fluid change when it was 160,000 kms. I did the change + filter at 221,800 with Mechatronic seals, adapter seal and 4 sealing seal. This was done at 40C.
3. Replaced the transfer case fluid (BMW) + rear differential fluid at 221,800
4. Replaced Glow plugs + glow plugs controller (Inpa shows error for this too).
5. Replaced with a used gear selector unit (GT1 shows 5088 gear selector error).
6. Replaced new automatic transmission thermostat + expansion radiator tank.

But none gives me a permanent fixed. I can use reverse gear even the error appears. When errors appear it sticks to D only, S or M won't engage. When the error appears, it will trigger the error only on D (even when engine is not running and moving the gear selector to D would trigger the error).

Yesterday I got the error code around a quarter of temp. gauge and drove it at 60 kms for 30 mins, stopped to pick up item for app. 10 minutes. Drove it again without any error at all.

Today I drove it and same condition, a quarter mark the error popped up. I stopped but it didn't fixed the problem. Did this around 10 times but no luck. Every time I turn off the engine and start the car, it won't throw the error until it moved to 'D'. I monitored the transmission fluid when it reached 102C (engine temp was around 66 - 75C), and I started the car again (no error yet) and moved the gear selector from P, R and N only, back and forward for 3 - 4 times, and then put it to D - no error message. The transmission fluid temp was around 97C when it finally engaged to D without error.

Drove it again later on this evening and a quarter mark passed but no error. Put diagnostic (inpa & GT1), but couldn't figure out.

Here is the inpa report:
