Just recently the trans in my car doesnt like to stay in gear when I downshift to decelerate. If I put it in 2 for example it doesnt seem to down shift at all, but when I get on the gas it seems to stay down in that gear and lets the motor rev.

I thought this is kinda weird, is she on the way out?

 

when mine did something like that, i had cracked some kind of pistion that engages tthose clutches.

time for a rebuild.

 

or maybe a T56

 

Your description is a little vague, but this sounds like it may be the lugs on the over-run hub, of the input sprag have broken off. This is a common problem in a 4L60E that is manually downshifted frequently.

Makes sense, it seems like it stays in the lower gear but doesn't engine brake. When I get back on the gas it stays in the gear I was in and doesn't upshift


Safe to drive for a little bit or is it gunna grenade on me soon?
