Auto Trans question

[stockyvrcalais]

Hi all, I have a VT Berlina that was factory 5 litre but now has a LS1 and auto from what I believe was a VY, when it gets hot (operating temp) the trans "flares" through the gears wether upshifting or downshifting, any ideas what could be causing this?

fluid level correct? Fluid not burnt, nice and clean bright red? Have you got a decent cooler on the tranny?

thin oil can do this

should be serviced twice a year if doing lots of KM

while doing that service test the electrical solenoids

i have noticed if I push it in second gear, it slips.

oil level and color seems ok, might service it anyway

somethings not right

it slips when pushed

and the original motor and or gearbox may have been swapped out

could be the front clutch pack just done replacing mine

thanks guys, after driving it around for a while it seems to be only 2nd gear that's the problem, flares going into 2nd, and coming out into 3rd, all other gears, 1,3,4,and reverse are fine no slipping, but second slips.

too costly for a partial rebuild

you could keep an eye open for a second hand box to fit when it gets worse

well I gave it a service, and replaced both shift solenoids, but only a very small improvement, still slipping 2nd gear
