Hi.
I have a 1987 Bluebird with a 8v92TA and Allison 741 (electronic version of the 740).
Tranny is going to need replacement soon. Are there any 5 speed automatics that will drop in repalce?
Also has to have retarder provision to replace the current 741 with retarder.
Thanks. |

Don't want to rain on your parade, but why would u want to replace it w/a 5 spd.? All u gain is a granny gear that u really don't need. |

Many years back we switched to five speeds and than went back to the 741. The upshifts are smoother on a 740/741 versus the five speed although the downshifts still have a lot to be desired. jc |
