mack-maniack Posted May 2, 2016 Share Posted May 2, 2016 Hi! im gonna build a truck with a detroit 4-53 engine and then i wonder what transmissions that will fit this engine, is it a standard bolt pattern on all the old engines? ive seen trucks with all kind of combinations engine/transmission wise, so it seems that most boxes will fit most engines, but before i start buying parts i want to make sure what i can buy for the detroit, so please post some info! :-) Quote Link to comment https://www.bigmacktrucks.com/topic/45059-detroit-4-53-transmission-options/ Share on other sites More sharing options...
jkruss82 Posted May 3, 2016 Share Posted May 3, 2016 Flywheel housings do have standard SAE bolt patterns that will match to all heavy duty transmissions. You will want to pay attention to your clutch and flywheel selection because all OEM's have different amounts of clearance. A Mack 9-spring clutch will probably not fit in any transmission you select. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/45059-detroit-4-53-transmission-options/#findComment-332254 Share on other sites More sharing options...

harrybarbon Posted May 5, 2016 Share Posted May 5, 2016 my dad had the 4-53's in Inter R - 190's - the trucks had 2 gear boxes, one was the standard 5 speed Inter box with 2 speed diffs and others had 10 speed Road - Ranger, you can have a direct or overdrive box, if you want some extra speed go for the 10 over drive, I do recall that the flywheel housing matched the R/R box, clutch you may need to check . The 4-53 and 10 speed were a great, strong and reliable combination. Need to get suitable diff - again an R-190 diff or the R - 200 Diffs are strong / powerful diffs. We recently sold a1965 Inter R-200 with a Cummins 180 turbo motor with a R/R 10 speed overdrive, a 2 speed diff and Page and Page pusher axle, it ran easy 65 mph What truck are you building?

Allen hutton Posted April 29, 2019 Share Posted April 29, 2019 I have an Australian made 1970 Dodge AT4 129 with a 318 V8 Chrysler motor and NP435 transmission. I would like to replace the motor with a Detroit 3/53 or 4/53,. Will my transmission be suitable or what other options are there?

j hancock Posted May 1, 2019 Share Posted May 1, 2019 If the trans. is in good shape, it should be able to take the torque of the Detroits. You will need to run the numbers to see if a rear axle ratio change is in order for a switch from gas to diesel depending on what you want to do with the truck.
