Trans doesnt like going into reverse

86 cutlass supreme 3.8 v6/auto (metric 3 spd trans) with only 61,000 kms. when ya put it in reverse, the idle comes down like its in gear, but its not. there is an audible hiss (vacuum?) but not at all timeswhen this happens. hoping its a sticky valve body. it will eventually get into reverse but it sure takes its time. once its finally in, its holds firm in gear. all forward gears work fine. note: the fluid is probably original based on the low milage (not burnt smelling). answers?? ideas??

Look for a vacumn leak ??if not then put a litre of diesel into transmission and drive it around for an hour then drain and refill ,might not work but sometimes it does on older boxes with all this flash computer stuff on them

Trans doesnt like reverse


That is a good trans - damn near bullet proof, change the fluid and filter and replace it with B&M trick shift or ((Hurst Hot Shift fluid)) these fluids preserve the bands and gives firm shifts instead of the lazy slip into gears , you will notice a really big difference in the efficiency of the trans and nice shifts as well - only need to change whats in thew pan, also while you are under there check your linkage because sometimes it needs re adjusted (adjust on the thing that is a round cylindrical thing with a bolt on the side - your shift rod goes through this) have a partner get in ((after)) you loosen the bolt and have them put the needle on the dash centered on the (P) - retighten

1995 cutlass supreme transmission


It physically will fit and bolt up,but there are many different ratio,and drive and driven sprocket tooth counts,different final drive ratios,all monitored by the computer with electronic speed sensors.If the trans from the 95 has a different ratio than the 93,the computer will set gear ratio error codes,and possibly put the trans in a failsafe mode,stuck in 2nd or 3rd gear.On the transmission case,down by where the passenger side axle would go in,is a thin metallic tag,maybe 2"x 3",and it has bar codes,and also a series of numbers and letters.The numbers and letters,large cap,are the final drive gear ratio code.They should match on the two transmissions in question.
