BMW 318 auto E36 Autobox - TCC stratagy question #

Year of Manufacture *: L reg
Auto box is an A4S 310/270R
All seems to work nicely with no slipping/noises or judder except that the TCC doesn't seem to operate until I reach around 55MPH. (When it does, it seems to engage positively with no slip or delay)
Now, according to what I have read, on this box the TCC should operate on third and fourth gear. That being the case I would have thought that some sort of TCC operation would be occurring from as low as 30 MPH onwards and this clearly isn't happening.
Would anybody know/have access to data relating to the actual TCM control strategy. Under what circumstances (Speed, load etc) are the gear changes/TCC intended to change and operate.
