BMW 540 was manufactured since 1972. This popular model is still being manufactured in sedan and touring or Gran Turismo body styles. It's available in automatic or manual transmission.
BMW does not have a recommended millage for a transmission service on a 1997 540-I.
The transmission fluid plug on a 997 540-I is located on the passenger side of the transmission, toward the rear just above the pan.
BMW does not recommend a millage when the transmission should be serviced on the 1997 540-I. To ensure a long life from your transmission, mechanics recommended changing the transmission fluid every 75,000 miles.
Before you can change the transmission fluid on a 1997 BMW 540-I you need to remove the plug and drain the old fluid. The new fluid is poured into the top of the transmission in the hole marked for transmission fluid.

Do you mean 525 IA, 540 IA etc? It stands for fuel (I)njected (A)utomatic transmission
