Have a C5 from a BII-- Dont suppose it will happen to fit the back of a 4.0 (Explorer) If not, is there a factory bell that will adapt it??

Thanx

it will fit.

Should have mentioned that this C5 came off of a 2.8, not the 2.9 that the 4.0 is based on--still good??? Also is the bolt pattern the same for the cammer and the pushrod 4.0??

it fits.

Got one in my B2 with a 4.0. You will need to relocate the crossmember (drill new holes), and mod your driveshafts.

C-4/5 to a 4.0

C5 has a different bell from a C4, the two don't interchagne.

the c5 bell will bolt up to a c4, the c5 bell is made for the cologne engines, the 2.8 2.9 and 4.0 there are a couple write ups about this swap.

c4 notes (http://mmerlinn.tripod.com/f/c4notes.htm)

It works, I have one behind my 4.0ohv.
The differences are I believe between pan mounted dipstick c4's and case mounted c4's, the bellhousing bolt up different.

Going from an A4ld to a C5? Here's a write up I did. This was a trail only rig, so I didn't bother with wiring up reverse lights and whatnot. But it will get you going.

Whoops, looks like Wilber already posted my thread.

Excellent info- Thanx guys, looks as if it will be fairly easy.

It is about as close to a bolt on swap as any out there -- if you have the correct bell housing -- which you do.

On some later models of Ford, you may have to plug a part of the transmission electrical harness from the late model transmission into the wiring harness so that the computer will not throw a code. Just tape it up and stick it in the frame somewhere.

You can't use a C5 Bell with out the C5 lock-up converter... C4 converter will be too short to work.


MMerlinn stuff is a great resource, should've post the direct link instead of linking to anohter forum...

right you do need a c5 converter, but you cannot get a new/reman lockup converter anymore. they'll all be standard converters.

I called around and couldn't find any also...

I was going to post the same thing... You can get converters from any major converter manufacturer in stock configuration, which would likely be best for general off-road use anyway. I wouldn't want a high-stall converter on the rocks... :eek:

If you can't find one, PM me. I have a local transmission shop that can provide them. We've already been through the book...

i was just saying that the bellhousings swap, forgot to mention about the c5 converter


fixed to the direct link

Lets go off on a couple of tangents here if I may-

1 would the auto overdrive tranny be the same in a 93 and a 99 explorer??

2 what are the differences between the C4 and C5 trannies??

the c5 has a lock up tq and the c4 has a better valve body, there are some other differences but these are the main ones i can think of.

the auto tranny in a 93 sploder is junk

would the auto overdrive tranny be the same in a 93 and a 99 explorer??No. The 93 Explorer has the A4LD, which is complete junk. The 99 Explorer will either be a 5R55E (5spd auto, SOHC V6 only, not that great but still alot better than an A4LD) or the V8's 4R70W which is a good tranny but will not work either.

You only have 3 choices to get a decent tranny in a 4.0 OHV Explorer motor-

1- swap to a manual M5OD

2- go the C4/C5 route

3- swap in a 60 degree 700R4 with high dollar adapters

has a kit to put a small block ford tranny behind the 4.0
just another option.

Ah yes, thats new. I forgot about that one, thanks.

The c5 is the better case.

Best bet would be to use the c5 case, bell, tq, and rebuild to v8-c4 specs.
The c5 has a better pump and some oiling modifications above the c4.

Well heres what I was trying to accomplish- over the weekend I went and looked at two seperate explorers, a 93 with a bad tranny, and a 99 that has been rolled hard. Was wanting to put the 99 tranny in the 93 for a driver, then put the C5 in the 99 and use it for a flogger rig. Looks as if the C5 issue is do-able. Now that I know the autos are different between years, anyone know if there would be diferences in T-cases, driveshafts, wiring??

The hardware will swap around from year to year (the 5R55E IS an A4LD with an electronic valve body and a couple of internal mods for additional strength) but the electronics will not. The 5R55E needs the computer to operate -- period.

You can build an A4LD to the stronger 5R55E specs with some careful parts matching.

The A4LD isn't all that bad, though. Just treat it right - keep it cool - don't try bang-shifting it and it will live a long time. After all, it and the 5R all have the same sized clutches and bands inside.

Here's a couple good links:
