I've got a '89 Suburban 3/4 ton with the 350 with TBI and 400 tranny. It's my backup vehicle and not driven much. It's always idled strange like it struggles to hold a steady idle, trying to surge and slow down repeatedly.

And now the tranny disengages sometimes when driving 40-50 MPH and the engine will race and all I can do is coast till it eventually kicks in again. Doubt if these are related, but not a fun day. On the engine, the distributor and IAC and O2 sensor are almost new, and all the tune-up parts are almost new. I don't want to spend a lot of money on shops trying to figure it out since the vehicle is a beater, but it's always been a reliable spare. Any ideas?
