Clutch problem???

[Scott Milliken]

My 1991 bronco won't shift into gear, d 2 or 1st... Reverse works but it's rough and takes a long second to grab. I'm thinking it's a clutch issue but a full rebuild might b the answer, anyone have one for sale email me

yo,

Is it the M5OD tranny?

Anyway, inspect shifter fork and pins

It's the e4od tranny, it just all of the sudden started slipping real bad and then nothin but reverse works.... That's what I was thinking it was, the shifter pins, but I can hear it shift in to gear but nothing happens

 

[miesk5]

yo, ok

Is the E4OD's TCIL (OD switch-LED) blinking?

Check for Code first;

a Self Test by my buddy and Bronco driver, BroncoJoe19 @ http://broncozone.com/topic/14269-code-reader/page__pid__74587__mode__threaded

heat the engine up; idle unitl temp gauge is in normrange you usually see

and wwhen it warms up; shift thru all gears incl Reverse anyway.

Then turn off all accessories/lights, etc.

Make sure A/C is off and transmission is in Park (automatic)

Do Key On Engine Off (KOEO) portion first.

Look Codes up in my broncolinks.com site using the new Search function.

And Post em here according to

KOEO

& KOER

Have you done the basic checks, such as fluid level; when at norm op temp; after running thru all gears & reverse, and fluid condition; no burnt toast or whitish (water) deposits on dip stick., etc.

BTW, have you or any shop done any mods or work with a connection to the brake circuit, or that electrically interfaces with the brake lamps in any manner?

Some possibilities, but don't buy or do anything related to these yet:

NO 2-3 Upshift TSB 98-16-7 in 90-94 Bronco, Econoline, F-150, F-250, F-350, F-53 Source: by Ford via Chilton "...Some vehicles may exhibit a no 2-3 upshift condition. This may be the result of cross-leakage caused by distortion of the control valve body separating plate. Perform diagnosis and, if necessary, replace the control valve body separating plate. Refer to the following Service Pocedure for details. Perform diagnostics as outlined in the appropriate Service Manual. Refer to Figure 1 for the models affected. If condition still exists, remove the control valve body separating plate. Wipe excess oil. Examine the separating plate for deformation in the intermediate band servo area, Figure 2. THE SEPARATING PLATE GASKETS MUST BE REMOVED TO SEE THE DISTORTION. If distorted, replace the separating plate with a new Control Valve Body Separating Plate (F4TZ-7A008-A). Install new Separating Plate Gaskets (F4TZ-7C155-A and F4TZ-7D100-A) and a new Oil Pan Gasket (E9TZ-7A191-A)..." see site for figure

wire harness may be pinched/shorted on steering column support behind the dash where the 14401 wire assy may come in contact w/a sharp edge on dash panel wall, I had same short here too & caused E4OD's TCIL (OD switch-LED) to blink like a friggin pia;

wires pinched @ brake/tail lights, my 96's stop/turn/tail lights wires were almost cut in half on passenger side against 1/4 panel (inner);

wires pinched @ high mount brake light

& @ driver's left hand seat belt anchor bolt @ base of B Pillar. See the location diagram

also, check fuses 1, 5 & 10: 5 is most important.... check for voltage on both sides of fuse aside from usual visual check

Here is a wiring daigram for a 90, but I think it is 100% same as rel. to the E4OD

It was low on fluid and the guy I bought it from said to put fluid in it and I should b good so I did and nothin changed, the dipstick smells like bad eggs so I asume it's the clutch is burnt up, the OD switch is missing so I couldn't tell you about the led light. The rear lights work fine so I don't think any wires are cut but there is alot of aftermarket stuff including 35inch tires and a 7in lift and a 1993 body. I'll put a pic up soon

yo Scott,

ok; the odor, etc. isn't good.

You'll need that TCIL LED/Switch soon anyway to be able to drive it and do the KOER portion of the self test. Try the KOEO test anyway.

Look @ the diagram by Ryan for the colors on the TCIL

Will a 1982 302ci tranny fit?

 

[Scott Milliken]

Because I found one that I could get for like $300

 

[miesk5]

Cool, thanks again

I took it to the shop because I didn't have time because of my job, but the problem was that the forward gear clutches and the torque converter was fried
