I think i hsve a big problem.

[ktmguy5786]

To make a long story short I have a 1990 Ranger 4x4 4 speed w/overdrive 2.9 v6 . I was taking a trip to the store got on the hwy. Put it in over drive and when I did I heard a clunk noise and my motor stalled. I've been hearing a whining noise since last week everytime I've put it into overdrive. I pulled it off the road looked under it and found nothing wrong. Got back in it starts right up goes into all the gears just fine but it sounds like I have metal in a blender?

Why I posted here is because I'm not thinking its in my transmission but my transfer case maybe? Anyone got a idea on what the problem could be?

check the oil conditions in the trans and t case? m5od or 146??


sounds like bad bearings in the countershaft.

 

[stegomon]

if it is an fm146....trans is on it's way out. m5od....tcase? or rear/front end pinion bearing?

m5od or 146??

He said it was a 4-speed OD. Sounds like an A4LD to me.

The 146 and M5OD were 5-speeds.

 

[stegomon]

Well I have seen shift nobs that say 4 with the 5 being a d on it

I'd guess he means a four speed plus overdrive. Would be easier if people just said five speed haha.

Doesn't matter, that's still a 5-speed. 5-speed means it has 5 forward gears, it doesn't matter what the ratios are. A 4-speed with OD denotes a transmission with 4 forward gears, the highest of which being an over-driven ratio.

adsm...i see what your saying and it makes sense if your from certain areas of the country or under a certain age....


but his post is clear to me as a manual trans that is a 5 speed or a tk4 was swapped in it. i originally thought a4ld, and with it going into od and killing the engine i almost have to say it has to be an auto...likely a failed tcc....he may have 4 gears now but no lock up converter.





but...i have been wrong alot about this sort of stuff. a4ld may be what it is.

its most logical from the stall on the run.

Yeah, if you are old enough to remember when they started getting overdrive by putting those case-splitter units on the end that kinda acted like a two-speed t-case with no front output.

I could see that being a "4-speed with overdrive" as the trans itself only has 4 gears, but then the OD unit is separate.


It really grinds my gears when people refer to the M5OD as a "4-speed with OD" because the breakdown of the name is "Manual, 5-speed, Over Drive"

^^^ what is?

 

[stegomon]

Well where is mr. Ktmguy?

 

[adsm08]

Well, anyway you cut it, sounds like sh1t's broke, take the trans out and look inside.

 

[ktmguy5786]

Sorry guys I've been out of town for work. The trans is a manual its a fm146 don't know much about them. My buddy told me it might be a throw out bearing failure.

 

[ktmguy5786]

Like I said before it started whine when I put it in overdrive a few weeks prior to this happening but didn't think it could be trans related due to the fact that from what I've been told that if its something lets loose in the trans you wouldn't be able to shift or it would act like you didn't have a certain gear set. So that's why I was thinking it was in the transfer case. I'm pulling the trans this weekend so hopefully I'll figure out what's going on.
