I have a 95 saturn, and just recently,when I am driving along and I slow down to make a turn when I go to increase my speed after going threw the turn, it seems to take a long time to shift. it has done this 3 different times in a 3 month period, could this be a solenoid problem? it is a 95 Saturn sc 2 with automatic transmission, it has about 171,600 miles on it now

@Iseekoutthetruth

When was the last filter & fluid change?

Your at about the right mileage for a valve body rebuild :(

Are you the original owner? The transmission may have a lot of wear and tear on it, so to speak.Have you tested the solenoids? what are the readings?

Take readings while completely cold & while hot. Record the readings & let me know what they are please.

hi i have a 2001 saturn sl2 and it doesnt seem to shift until u hit certain speeds and if u let off the throttle all the way after hittin 35.. i am only getting 25mpg max and i believe it is cuz it doesnt shift into the lowest gear possible. could a soleniod be causing this. i have tested them in the car and they seemed ok. please help.

Test at different temperatures. cold & hot, not just one temperature :)

when was the last time a fluid change and filter was done ?

Excellent instructions - both on removal of valve body and diagnosing failed solenoid. My 2002 SL1 was reverse slamming then began to bang shift from 1-2 and 2-3. Removed valve body - disassembled - bench tested - line pressure solenoid out of spec. Paid $68 for an OEM solenoid replaced - buttoned up the valve body and re - installed. VIOLA - shifts like a champ and smooooth reverse now. Thanks for all the info!!

@Iseekoutthetruth also test them cold and when the engines good and warm cause they can be fine cold but warm one or more can throw more than a ohm difference...

for instance mine read the other day (3rd) 5.2 cold 6.0 hot (4th) 5.3 cold 6.1 hot (TCC) 5.3 cold 6.2 hot (line) 5.5 cold 6.2 hot (2nd) 5.4 cold 6.2 hot. I just got mine it's at 167K miles and all the fluids were horribly over due. So part of your problem is what @FiremanCV said cause a transmission flush helped me tremendously. $140

@Iseekoutthetruth He has another video showing how to do it without the valve body apart. do what I did and take his info on that video and just remove the plug and test them still in the vehicle. its between the battery and master cylinder. there's enough space to do it and its a lot less work. cause I have a similar story as yours shifting hard at times and mine mainly slams in reverse. a code was throwing for solenoids and it wasn't even the problem.

@FiremanCV I am the second owner, I am going to change the filter this weekend and fluid. how do you test the solenoids. do Ihave to take it aprt to do that? if I have to take it apart should'nt i change it than? how do I check it when it is hot, is there a area to do this with out having to take it apart?
