Re: th400 into my 74. help????

["Simms" <MrSimms7@xxxx>]

to clear it up on this board...the Jeep TH-400 is an AMC case w/ the 
GM guts...just like what they did w/ the torqueflights...

you need the short tail shaft and housing out of ANY make TH-400 and 
swap it over...now would be a good time to rebuild the trans...

the speedo...jeeps do have them in the t-case...tho the trans case 
does have the impressions of where the speedo driven gear housing 
would go...almost looks like it has a plug in it...but it is the 
actual casting and would have to be machined to be able to run a 
speedo...also if you do plan to get it machined...you need to make 
sure that you get the right drive gear on the output shaft so you can 
have the right selection of driven gears to make your speedo right 
for your current setup (rear ratio and tire size)...also plan ahead 
here so if you decide you might change ratios or tire sizes...

my car I'm using a 15/41 (15 drive gear and 41 driven) also using the 
speedo cable from my 904 on it...dunno if its gonna turn out bad or 
not cause I just got it finished yesterday...tho the speedo does work 
and appear to be correct...

and if anyone is interested...Coan Engineering built my trans...
