| Post subject: | Location of starter motor |
I have a D100 pick up with a 3 speed, and a 225 slant. The starter motor is mounted low. Don't have a lot of cars or trucks to compare, only pictures. My questions : The stater located higher on cars because of auto transmissions ? I would like to install an automatic 904 or 727 is there a problem making the switch ? |

How "low" is the starter mounted? If it's above the oil pan rail, it's the high-mount (ordinary normal slant-6) location. If it's below the oil pan rail, it's the low-mount (ordinary normal V8) location. Neither situation will interfere with a transmission swap. |

It is below the pan rail. There is a triangular brace from transmission to engine block above it. The transmission is 3 speed manual. I that brace needed on automatics ? |

Okeh, that's the "low" (V8) starter location. You have options. You can either fetch a slant-6 automatic transmission and move the starter up to the slant-6 location (and sell the adaptor ring and spacer to help defray costs of the changeover; there's a market for 'em) or you can keep the adaptor ring and spacer and fetch a V8 automatic transmission. Yes, the engine block to bellhousing braces are needed. One other thing to watch out for regardless of which option you go for: your truck may have a direct-drive starter rather than the gear-reduction variety. They aren't interchangeable; the direct-drive starter has a 9-tooth 25mm drive pinion and the gear-reduction unit has a 10-tooth 33mm drive pinion. You can carry on using the direct-drive starter (which will mount in the low or the high location according to the bellhousing on the transmission you choose) but you have to have the correct torque converter ring gear. It'll be easiest for you, if you presently have the direct-drive starter, to switch to the gear-reduction type -- either the regular Chrysler variety or one of the newer mini starters. That way you won't have to specify a custom torque converter with the '60-'61 ring gear that'd be compatible with the direct-drive starter. |
