is if full of Dexron VI now? TO THE COLD MARK?
and after startup, in park, it holds the cold mark?
then rises to the hot mark.>?
so the old trans was dead, so you bought another used, trans, that is 21 years old and expect it to work great? ok....
and did you drop the pan, and replace the filter?
the pump can suck Dexron VI through a packed filter.
and while the pans is do you have the shift soleniods here.
if yes your trans has a TCM and does all shifting,
but manual mode would work if, TCM is unplugged.
so if you manually move the side shift lever. to drive, Lo or reverse
the car will not move. im I right.? (false neutrals?) right?
why not say what it does.. not just (not engage) (creeps in gear?)
does the transmission act likes its in neutral? and RPM rises fast with right foot and car fails to move?
don't use the shift lever, use the transmission side lever. to prove the trans is failing
94 rodeo.... first i must look up what trans is there.
there are 2 types. (hyradmatic, and TCM electronic)
see? and many car makes have both types same year, yes,,, that makes for online help near impossible. lacking the side plate
numbers on the ORIGINAL trans..... a fact !!!
all answers are USA cars. (USA forum it is)
I will now quote the FSM (factory serv. man.) book facts for 1994
The 4L30-E transmission, the E means , electronically shifted.
needs a working TCM to shift all gears automatically.
tcm = transmission control module, (can be by self or part of PCM)
did you adjust the shifter like the book?
see bottom photo.
if reverse is dead, then the below is set wrong or trans is bad.
(or lacks proper fluid level or the filter is packed.)
the lever is held at N, with a rubber band
and the mech, adjusts the trans lever to N.
(standard steps on all a/T boxes)
this is the French GM trans in your car.
its electronically shifted. if not, its a true Hyrdamatic.
got those 3 solenoids. is the connector below , connected?
my best advice, get reverse to work first...
that is 100% hydramatic mode. (lever to R , at drivers hand and lever at trans in R detent !!!
