It could be failing clutch packs or a failing torque converter. I had a TH350 that whined after upshifting to 3rd, then it quit. For me it was the torque converter. It took out the entire transmission, including the oil pump.

I have a 1994 chevy Van G20 series it will go in reverse and in low gears but wont shift


Check your E-break first, secondly check to make sure you have no errors kicking from the control unit (engine computer module) which may or may not trigger a check engine light. Moreover it could be several things. Since it's an automatic the drive train maybe damaged, controller unite could be damaged, the transmission could (and probably) is dying. I'd have a professional mechanic check it out.

95 G20 van transmission IN a 94 G20 van will it work and what would I need to modify to make it work thanks


4L60E 4speed automatic most likely. Very common in a multitude of GM products since the early 90's. Should fit with no modification. Best to measure your old tranny from bell housing to tailshaft and compare to the one you want to use. That way you can determine if your tranny mount and driveshaft will be a good match. Should be ok if they are both the same model tranny.

My 1999 chevy astro van tranny is slipping


aslong as your tranny is still shifting properly then it should be fine, try getting a fluid flush and a new filter and new fluid and that should fix it up, thats what i did with my 96 astros and that cured them both

Toyota pickup 1988 V6 Auto tranny does not shift into low 1


I guess the best , easiest & cheapest thing to do, right of the start is get fluid & filter changed, and lube all cables & linkages thoroughly, unless that's all been done recently.
