ok....sorry didnt search for along time..kinda in a rush to find a ride to borrow.

short of it....was going down the road...stopped at intersection...noticed rpms jump slightly...sat waited for light and...NO GO!!!

i tried to engage front axle to move...axle will engage, no power though...fluid is good...no burn smell.
cable moves freely and i can see it shift at the tranny.

i am guessing i blew tranny finally.
so i need to find one to swap in asap while i find funds to rebuild old one over summer.

am i wrong? any thing else it could be?

there are no codes or ses lights...4x moves thru all stages.
driveshaft feels tight when i try to rotate by hand.


any advice would be great....preparing for the worse

thanks guys.

 

have you tryed all the other gears ??

like 1st or 2nd? or regular drive ? depends what you have ...

 

I went thru all gears. And 4x combos trying to move it.
no power to the wheels front or back.
i can hear front axle engage and transcase shift....just no power to wheels.

Never made any grinding noises either....just sounded like it dropped into nuetral and stayed there.
I had it in first with wife behind wheel letting it idle and i could push it backwards...

 

What about the wiring going to the shift solenoids & or fuses? Might be the torque converter. I know when my trans cooler blew a line off it was sluggish while I crept off the road with the TC pumping fluid out the line & all over.

 

Have you verified that the shift cable is still connected? Does it go into park properly?

 

Yeah no noise or grinding & a sudden loss of power when at idle doesn't seem to be internal, mechanical issue. Unless a or some seals suddenly popped.

Is the trans controled by the PCM or BCM? Something that sudden & noiseless screams electrical to me. It IS a 4L60E afterall

 

Yes..i had wife shift cable while i watched and checked for movement on it.
no....i did not check fuses...forgot about electronic side of it
how can u checl torque converter?

 

Not too sure on checking the TC but 1 way to see if it's pumping is to take off the trans cooler line leading to the rad, put the end in a bucket, start the truck & put it in neutral or in D. It should pump fluid out.

 

Ok....i had to get wifes jeep to get kids....will go back and check fuses and wiring....with fingers crossed.
Thanks for the advice so far....i will report back soon as i can.
totally forgot elec angle of the issue.

 

GL Jarad!
