Upgrading trannies, will a Dana 300 bolt right to the TF727? I am getting mixed answers and a lot of uncertainty. Thanks for the help!

DO A SEARCH!!!

Yes the D300 will bolt up to a TF727.

Depends on what the 727 came out of, if it's a Jeep yes, Dodge or IH no. If your pulling one from a Grand Waggy try to find an early 80's so you can avoid the lock-up convertor.

I do not know about the IH737 but the 300 WILL BOLT TO THE DODGE 727.. and I am pretty sure the IH version uses the same output spline size and count so it would probably only require the Dodge or Jeep T-case to tranny adapter..

You have to drill a couple of new holes to use the dodge. The IH requires the output shaft to be replaced. The bearing does not line up properly.

I do not know what T-case you were putting the 300 in place of but I did not have any of the problems you claim to have had.. I put my 300 in place of a 208 using the stock adapter in stock condition.. NO drilling-NO problems with bearings.. I do not know what bearing you had that was not lining up properly but the only bearing in mine is the one that supports the tranny output shaft and it is too far in to have any effect on the 300..

d300 will bolt up to a 727 out of a waggy or cherry or J truck from the 80s

lockup AMCTF727s are rare as hell. i sure would like to find one! :p

every single 727 i've ever seen have been non-l/u. it's reputed that the ones in waggies with 2.73 gears are lockup, but i've never seen one.

oh yeah...

use the damn search button! :rolleyes: :flipoff2:

Not trying to steel the thread but explain lock-up and why it is desirable or un-desirable!!!

I am putting a lock-up version in a wrangler this weekend!!!

Because it was a poor design, and the clutch in the TC did not last long pushing around a pig waggy. In your lighter rig it might work out, then again you may experience lock-up in low with high RPM's when you need the TC to slip.

I think it's the Dodge's with a 203 behind it, the bearing I'm referring to is related to the IH case and output shaft.

That explains it.. The 203 uses its own unique adapter and is different from the 205/208 adapter..

Thanks for all the help, looks like I am gonna make out on this deal, thanks to everyone who posted!

As for using the search button:flipoff2: I already had tried that route and found nothing definate that I could use, there is all the info in the world out there for TH350 TH400 and 700R4, but almost nothing on Chrysler transes so that is why I posted here!

nope :rolleyes:

Why do you say nope? Mine bolted up nicely and if youre refering to pan clearance, with a 2.5" soa you have no problems... at least I dont...

Seeing the little :rolleyes: made it look like his intention was sarcasm, hence the picture of the Dana 300 bolted to a 727.

From a previous post, people said that the only way to fit the 727/d300 was to modify the tranny pan, i was just showing that there was no need for clearancing on my rig... and i posted pics to prove it.

ding ding ding ding!

:rolleyes: = sarcasm

and i have a AMC 360 with a TF727 in my jeep (for 2 years)....:rolleyes:

Im to doing this swap, are there any problem with drive shaft issues with full width axles? Also who has done this swap in a YJ I got a few questions for ya, thanks

Why would there be driveshaft issues because of full width? Using a 727 in a YJ eliminates the clearance issue you have with a Dana 300. The driveshaft is on the other side of the pan and there is no bumpout to clear on that side. Any driveshaft "issues" would be no different than with any other tranny you choose. It's not the axle width that's the problem with a CJ, it's tranny pan clearance on the right side. Full width axles sometimes help on a CJ if the pumpkin is moved to the right relative to the stock axles.

what type of shifter did u go with??? just wondering was planning on this swap this winter

Im running the B&M Megashifter and love it... espessially not having safty neutral switch hooked up allowing starting in gear...

do not...i say do not get a b&m z gate shifter! they are cheap and suck major ass! get an art carr shifter or the lokar's are real nice.

I've run these on three different rigs over about 8 yrs time, simple, reliable, can shift in my sleep and has ratchet action and lockouts to avoid missed shifts.

to anyone used to a non lockout car shifter they will drive you nuts till you get it down. My wife and teen daughter shift it fine.

worst case scenario on a 727 use a two piece shaft to get around the hump in the side of the tranny. I'm running a normal 2" shaft up the side of mine- I did move the yoke outboard a little when i narrowed and rotated the 60 front.

Good luck:D
