      ok, to answer everybody's questions.....

      JoshC:: yes, it is a 3speed
      HotWheels:: is the c5 tc a lock up? I'm not sure... I"ll check into it, as far the speedo cable, yes the factory one worked, but theres some bugs in it that right now that I have to check into later this week.

      I won't be able to work on it again until Thursday :( but I'll keep everybody updated on the breakin and the details I"m doin to finish up the interior.

      i had this chat a while back with a friend of mine who is a ford driveline tek just seem to remember him saying stay with the C4 parts as much as possible, from what i read about it just now the C4 converter will bolt to all the 2.8/2.9/4.0 flex plates (was surfin TRS tek forum) but there are some other issues that result in the converter not fully seating in the front of the tranny with certain flex plates.
      the TRS tek also says there are 2 styles of C5 converter and one is no longer available, the new C5 converters are non lockup.

      advance adapters V8 conversion info also says if you have a C5 and convert to a V8 you need a C4 valvebody and converter to prevent some issues with lockup but hey this is pretty shady ground yer walking on and a compleat write up on this swap does not exist as far as i know just bits and pieces of info.

      but from what you have described i would double check the vacume modulator on the tranny... if it's anything like a C6 or a turbo 350 they wont shift down unless that modulator is doing it's job and they will shift up but it takes about 5000rpm.


      i currently have a D20 J-shift on my work bench and a blown tranny in my X but am undecided on what to do..... your C4 swap is kinda inspiration to get my junk back on the trail :)

      This is what I guy with an EB and C4 told me.... he said not to worry about unless I get around 300 miles on it and it still doesn't shift.

      haha, it sounds stupid I know, but since all I do is rock crawl, and I can manually shift gears with my MegaShifter, I think she'll be ok.... b/c I'll be in 4lo the entire time and will only be in either Park, Reverse, or first gear (manually) . I think I'll be ok.

      OH I C so you have 1st gear if you use the shifter, hopefully your problems are jsut an adjustment then and not something internal

      yes, I can shift manually through 1st, 2nd, and 3rd gear on the shifter, but as soon as I put her into drive, it starts acting up..... I"m gonna double check the check ball under the tranny filter and see fi its there (its supposed to be, but I never remember seeing one, even when I first tore it down)

      well, I've gotten away from the project. b/c when I took it out wheeling, I blew up the rear end, so I've started workin on my full width axles that will be swapped in there....

      as far as the tranny, I haven't had the time to drop the valvebody and check the check ball, and vac mod. and such..... I'm hoping to get a chance later this summer (been VERY hectic laterly). and if I can't figure out this problem, I'm just gonna say screw it, take out the tranny and take it to a tranny shop and have them look at it.

      Sorry for so long with no update, as far as pics, you can go to my cardomain site and check them out.... www.cardomain.com/id/carfreak146

      This is the 3rd a4ld, and a friend of mine who builds drag racing trannys said this is the strongest il get it. Now when i put it in 1st it sounds like shaking marbles in a coffee can!!!
      I gotta do a c4/5 swap! I tryed it once before but when i bolted it up i was having clearance problems with the converter and flexplate. But i Pulled the tranny from a 4.0 ranger and it worked in That truck wich dosnt make sence.
      SO..... From what iv gathered here you need to swap to a 4.0 Explorer
      C-5 Bell, Converter, flex plate out of 85+ 2.9 v6
      C-4 Trans CASE FILL w/ shift upgrades
      And MoD the Xmember and drive shaft.

      Is this all correct? Please let me know.

      you don't necessarily NEED a case fill C4, I have a pan fill in my Explorer, but the Case fill does have a smaller case up where the bellhousing bolts to it, and with the case fill, you have the option of a deeper tranny pan, where you don't have that option with the pan fill C4s (like mine). I also learned that you can use the Flexplate from the A4LD to save a bit of green, but flexplates are so cheap, that I just went ahead and used one from an 85 BII.

      I've been looking for a c5 for a while now but no luck. These are floor shift right? What years are they in? Are in Rangers also or just B2?

      I've got a c4 out of a full size, but it's not a floor shift so it's useless for me.

      as far as I know. you can make the c4s and the c5s any "shift" you want. I thought about hookin my column shift up to my C4 but decided against it, just takes a little "fabbin" to get it to mount on the shift lever of the tranny.

      Hey Josh you can use any C4 as long as it's 74? or later because the shaft spline count is correct. Ryan did it right as having the right t-case adapter and output shaft that obviously came with the combo. You'll want a C5 1350 combo that was behind a BII or early ranger 2.8L v-6, basicaly flex plate back off a donor truck. You can easily swap the 1354 later if you want the flange for the front drive shaft. The only problem with the Dana 20swap is how the t-case hangs low but a well built skid plate will take care of that problem. And teralow 4:1 crawling gears are nicer than 2.46:1 as with the 1350/1354 t-case. One other nice part is the stock starter will work on this swap also.

      Oh by the way I have a Lokar shifter that mounts to the trans and a Art Carr reverse manual valve body(P,R,N,1,2,3) and have to shift every gear. Wish I knew how it worked though it's all still sitting by the truck, not even close to being under it yet.

      I believe the tranny is from a 80 f150 or something like that, but it's a 2wd tranny. I think i'll just try to find a whole donor setup like you said. I wasn't sure which motor the c5 came behind.

      Hey, another option is the 700R4 swap, got one in my 94xlt and I've been beating the snot out of it since 7/2004. No problems, had the tranny built with stout parts and strong shift kit, custom tc. With the 4:10's and the crappy No-Slip really wheels nice.

      I paid $1185.00 for the engine adaptor, transfer case adaptor, reverse light switch, Lokar shifter (You can't use the stock column shifter, this is much cooler having the floor shifter anyway) from MOAB Offroad. Then another $200 for the 4.0 throttle cable and bracket, and complete TCC relay kit from Bowtie Overdrives. So to swap it your self adapting a 60 deg. 700R4 will set you back about $1400 plus the tranny.

      I did this when I had the $$$ set aside, and it has paid off many times over. I went through 3 tranny's too, A4LD's just can't handle any abuse over driving like a Granny would.

      Edit: 2:53pm, another thing the 700R4 is good for, Hemi's. Had to run out and on my way home pulled up to a light with a new Hemi Durango, and it was on! Toasted him off the line up to 3rd gear then he passed me but it took him 2 blocks!!! That's good enough for me baby!
