im trying to search for info - but if anyone can tell me what the stock MODEL TRANS i have in my 84 733i that would be great -
and what is the BEST TRANS FLUID and HOW MUCH is required for complete fluid change
I think if you go to auto barn they have many refrences in the fluids section on what the car needs , dont know much about this stuff, but I think that would be a good thing to try
darkhorse737, I have downloaded a pdf dated 2006 from ZF where they list Dexron 2D for the 4hp-24. Spec TE-ML 11
I am not disagreeing with you because everywhere else on the web they specify Dexron 3, but ZF Spec. TE-ML 11 calls for Dexron 2D for the 4 speed plus lockup torque converter and Dexron 3 for continuously slipping torque converters, which the 4HP-24 is not. In an E32 750il the torque converter locks up at about 110 km/h with the effect of an overdrive kicking in. This site explains it better.
Yes, it appears that Dexron 3 supersedes Dexron 2D for it's better properties and is backwards compatible. But you can still use Dexron 2D in the older transmissions that call for spec. TE-ML 11A.
Did a fluid change on a ZF 4hp24 transmission last night. Dropped the sump- 6 bolts and dipstick pipe- removed the filter and opened it up. It's spot welded on three corners so cut the corners off and unfolded the edges with a side cutter. I'm glad I did this because the area under the hole to the valve body had about two teabags full of friction material accumulated there. I washed it clean with petrol and folded it all back together, as good as new. Re-assembled and filled with 4 liters Shell Dexron 2D and did a test drive. The transmission works perfectly, but, unless it was repaired at some time and the old filter was refitted without being cleaned, I don't know. At least I know that there is a good chance that one of the clutch packs will start slipping in the future, and I will know why.
