i just bought this truck its a 1979 dodge 300 club cab i dont know what transmission it has but it is an automatic it has a 360 motor the transmission went out yesterday in it it shifts to reverse just fine but drive threw d1 it makes noises did a fluid and filter change today i think the transmission is a 727 but not sure also need help with the wiring diagrams

 

May need to seek professional help.

 

A 79 360 will take a 727A. All big bock's take 727B and 6 cylinders use the 904.

 

Ok the transmission is a 727 I do have a 904 will it work till I get the other one rebuilt?? But is the tail housing too long and mine is a bolt on drive shaft

 

They are very similar, The 904 is more suited for lower hp rating as the 6 would be. You could use it temporarily if it will work with your truck. There where some differences in tail housings/slip yokes etc...

 

How hard is it to change out tail housings from a 727 to a 904 I can't find any info

 

You will also have change the output shaft if they are different sizes. Here is a video of a complete disassemble/rebuild.

 

Thanks for all the help I learned a bunch from.research and yall. But will a 727 with a longer tail housing that's mounted up to a 318 bolt up to a 360 both trucks are the same year

 

All small blocks have the same bolt pattern so yes. What ever tail housing was on the original is what you need.

 

Ok thanks again for all the help I'll give it a shot this weekend
