Introduced in 1989 and 1990 these transmissions are essentially the good, strong 904 and 727 trans with .69 to 1 overdrive added to the rear. 4th gear is controlled electrically, requiring a simple toggle switch to engage 4th gear or lockup in stock applications.
Dimensions are very close to the 904 and 727 except for length and extra bulk in the housing to accept the overdrive assy. All linkages including kick down are the same as the 902 and 727 easing swaps considerably.
