Most definitely! Try to lay the hose where you found it under the hood...and see what areas it will reach to. The area will you'll most likely find a connection is somewhere around the throttle body or intake.

A trick you can try is to take WD40 and spray around the intake area...when the idle changes - goes low/stalls....that's where your vacuum leak is; and is most likely where the hose goes.

If that doesn't work...invest in a Haynes/Chiltons repair manual for about $22.00; which has vacuum circuit diagrams that will lead you from component to component.

Need to see diagram for 88 jeep Cherokee Laredo straight 6 for vacuum line for transmission


in the USA? 4.0L engine.
TRANSMISSION VAC>.
So that be automatic.
and some have a vacuum modulator.
some dont.
if it does, its just a vacuum line from the modulator to the plenum.
the modulator uses hard vacuum to sense engine load, to delay shifting/

some EPA hood stickers fail to show this hose.
because its a trans hose and not related to smog.
only this is covered in the FSM.
surely you can find the empty nipple in the plenum
but is this and engine swap, and missing this?

I owned 3 1988 2 JX and 1 Comanche.

id find a vaccum line under full vacuum under idle. 20inches is typcal. (cant find real nipple?)
then add TEE fitting to this line and to trans.
end story.

there are 2 kinds of vacuum./
vsv solenoid switched, (like that on EGR)
direct plenum vacuum (bingo!)
and ported vacuum, weak or no vacuum at all at idle.

easy huh?, just use the hard vacuum line,, or make one.

I tried to give you a vaccum diagram but the manufacture will not release that info to outsiders. you need to find where the hose goes to.if you loose vac to the controls it goes to defrost mode.

1994 automatic transmission slipping


more than likely it would be your torque converter and not your trans
but you could have the overall dreaded problem that your second gear has grinded its self down and thats why you cant get second gear
no vacumes for the 94 straight mechanical and electrical if there was a vacume you would have found it when you dropped the pan it isnt hard to see around the whole trans cause it would be located next to the speedo with a rubber hose 1/4 thick
