89Cutlass Posted January 15, 2003 Report Posted January 15, 2003 In going to change my tranny pan gasket and filter today and am wondering how much fluid to put in from a gasket change. Is there a way to find out what type of tranny i have an 89 olds cutlass supreme 2dr 4speed auto with /o. Quote
Whiskey River Posted January 15, 2003 Report Posted January 15, 2003 Is it a 3 speed auto or a 4 speed auto? Quote
Whiskey River Posted January 15, 2003 Report Posted January 15, 2003 Since it is an '89 then they most likely still refer to the tranny as the 440T4, now known as the 4T60. I dropped the pan on my 4T60 and replaced the gasket and filter, took 6.5 quarts to fill it back up. I think the half quart was due to my arm tiring before tightening all the bolts and not getting a couple of them as tight as I should. The 6 quarts should at least bring it up to the low mark. Also be sure you clean off the magnet in the pan. If it has alot of shavings hooked to it then you may have some serious tranny problems heading your way. Quote
89Cutlass Posted January 15, 2003 Author Report Posted January 15, 2003 Thanks. well im of to advace auto parts Craig 1989 Olds Cutlass dr 2.8l Quote
89Cutlass Posted January 16, 2003 Author Report Posted January 16, 2003 It took 7 quarts to fill it up. AS for the magnet there were some shavings but not alot at all very few to be specific. thanks for the info Quote
Guest Anonymous Posted January 16, 2003 Report Posted January 16, 2003 The only time I changed mine the magnet was almost double it's original size cause of the metal shavings. I also found chunks of white plastic in the pan. I figured my tranny was going, going, gone... It shifted real hard and downshifted even harder. Found out it was due to the dogbones being shot allowing everything to jerk around. Got some poly ones and it shifts good for 175,000 miles. Quote
SleeperRed90TGp Posted January 16, 2003 Report Posted January 16, 2003 Don't forget to add at least two quarts of extra fluid to the 4t60 tranny after it's full. Where I had my tranny beefed up and overhauled they said that years ago there was a gm bulliten stating that we will get better longivity by adding three quarts above the fill mark. Mine is about 7/8 inch above the full line and has been that way for four years. I gotta change mine someday. They also recomended synthetic fluid. Expensive!! Quote
89Cutlass Posted January 17, 2003 Author Report Posted January 17, 2003 Ive always been scared to overfill my tranny beacuse i had a ford mustang one time and overfilled it by about 3 quarts and blew like every seal in it had to scrap it after that.. Quote
BlackSunshine Posted January 26, 2003 Report Posted January 26, 2003 I would make 100% sure before I add the extra fluid. I remember your Mustang fiasco there 89 and you don't want a repeat. But that could be the case so tread easily and skate straight. Quote
Guest TurboSedan Posted January 26, 2003 Report Posted January 26, 2003 i have heard that there is no problems overfilling the tranny, since the excess fluid will come out of the tranny vent tube anyway. joshua Quote
Brian P Posted January 26, 2003 Report Posted January 26, 2003 I have it overfilled by only 1/2 quart and I never had any problems with "slipping" on sharp turns Quote
nerfbars Posted January 28, 2003 Report Posted January 28, 2003 I have the same car. In 89 the 4spd trans is a TH440 "overdrive", the 3spd is a TH125. To change the fluid and filter mine has always taken about 5 to 6 quarts. Quote
Brian P Posted January 28, 2003 Report Posted January 28, 2003 Oh daaamn, nice car nerfbars! I had the same look with the lower rocker panels! Were you ever on LI cause I could swear Ive seen that car around! Quote
nerfbars Posted January 28, 2003 Report Posted January 28, 2003 Thanks I appreciate it! It wasnt me that you saw but I hope you didnt see one like mine. I've tried to make mine look nowhere near anyone elses. LOL Quote
Brian P Posted January 29, 2003 Report Posted January 29, 2003 well, the one I saw was dark blue, full bra up front, raised lettered tires but it had the 15" olds wheels. I love the 88-91 cutlasses and 90-94 Lumina euros with raised letters, it looks so badass Quote
ismellrealbad Posted January 29, 2003 Report Posted January 29, 2003 you hav a raised lettering fetish. raised lettering is only for boxy RWD cars that are fast Quote
