just had my trimatic serviced and for some reason it holds 1st gear for an excessively long time when cold. once its changed gears for the first time it works fine. but occasionaly when under load coming out of an intersection it slips slightly from 1st to 2nd. gear changes are smooth. the bands should have been adjusted, the mechanic said the oil and filter were suprisingly in good nick when he serviced it. the reason i took it in for a service in the first place was for the same problem it has now. as far as i'm concerned he's done nothing and charged me $140 and he reckons there's nothing wrong with it. the fact is it is slipping between 1st and second and i can even hear it slipping. does anyone know what could be causing this. every other gear change is perfect and smooth.
cheers craig
ps theres no transmission specialist in town.

Your auto probably needs attention by a good auto transmission guy. It may be a valve body problem or worn clutches. A normal 'service' will not fix these 2 faults.

i told him exactly what was happening. saying he did nothing was probably not a good choice of words. the next morning i had a pool of oil sitting in my driveway about 1.5 meters in diameter. so he obviously did something. wouldnt he have found an oil lea Edited by user Friday, 28 September 2007 11:09:51 PM(UTC)

G'day Craig,
It's been a while since i've built a trimatic but i'll test my memory.
the band is only used for 1st and 2nd gear if this was a problem it would slip in first and second gear only . The reverse clutch is just that, only used for reverse,

Oh yeah the no shift cold is most likely a sticky 1-2 shift valve ,possibly a small piece of Q.R. valve sometimes called a dump valve jamming it though this woul usually be a consistant prob hot or cold with a thump on downshift when stopping at lights. O
