Ive been told by several HD truck shops that you can readilly find an Allison 5 speed trans from a bus or other rig to bolt up to the CTD. Obviously some fabrication would be needed, driveline, linkage, bla bla bla. anyone done this yet???

 

Apache;<br> I looked into the same senario, the problem is cooling. The Alison needs a larger cooler than our stock cooler. :'(<br> What I learned was that there really isn't enough room w/ a innercooler, &amp; A/C condencer.<br> I also have a 93, after speaking w/ several folks at different<br>bussiness, Tranny shops, ect. &amp; the good folks here on DTR. ;D<br>I choose to convert to a lock-up TC, and trans. one of the benifits of this trans set up is much lower opperating temps. ;D<br> I'm working on a story w/ photos &quot;to air on this site w/ OK from Mr. Thorpe&quot; that will describe in detail how to make the conversion. The tranny I installed is a 94-95 model 47RH. ATS built extreem duty w/ tripple lock TC, is the best upgrade I could have done, the power gets to the ground. ;D ;D<br><br> ramguy <br>

 

not to be to prying, but what might one be lookin at $$$ wise for this type of set up.<br> Thanks. Apache

 

Details brother, details!!<br>What shifter did you use?<br>What changes (IF any) as far as wiring?<br>Do you tow?<br>

 

Apache;<br> Let me say this 1st I was looking at the 03's and the price wasn't the worst part :'( but $650/year for a tag vs the $130 for 93 helped in my decision and the fact that my ctd also is just broke in at 174k mi. ;D<br> Any how the conversion ran about $5,800., but I think it was worth end result. With a little small amount of BOMBING<br>this puppy's gonna pull anything I need and run efficiantly while doing so. ;D

 

Just for FYI I have an adapter plate the is required to go from a non-lock up trans(a-518) to a lock up trans. If anyone is interested I would make them a good deal. Thanx

 

What's different?<br>I thought the bellhousings were the same?<br>I know they use the same flex-plate (Later one is better)

 

Because the lock-up convertor is wider it sticks out of the trans therefore the adapter plate is deeper to accomodate the wider convertor.

 

I'll have to take one of my 24 valve adapters with me to Ft Walton beach then, Huh?<br>Glad I started stocking up on this stuff.
