lumidohc Posted March 14, 2014 Report Share Posted March 14, 2014 I was driving my car tonight (95 lumina ls w/ 3.4) and it was going really good. When I was on my way home I decided to get into it and to my surprise it wrapped up to 6k and the car didn't move.... After I let off the gas and continued to drive it, it did fine again. Wth is going on? My gear selector is easy to knock out of gear but I didn't touch the damn thing and it drove the rest of the way back home just fine. Any ideas? Figure i'd ask someone with some knowledge Quote Link to comment Share on other sites More sharing options...
z34Phoenix Posted March 14, 2014 Report Share Posted March 14, 2014 more info please... what speed were you going? could have hit governor? stock shift points on the 96 are 1-2 at 5952 and 2-3 at 6250 3-4 is 5150 at wot the car shifts via rpm as long as you are above the set mph. 1-2 is 42, 2-3 is 80 and 3-4 is 104. if all these conditions were met and it still didnt shift, i would think a shift solenoid or other issue is at fault.

RobertISaar Posted March 14, 2014 Report Share Posted March 14, 2014 no move = no friction. either a LOT of clutch slip, the converter going south or something weird is happening in the valve body(like if there weren't enough fluid passing through the filter, that will cause bad things).

I was only going about 30 when I stepped on it Quote Link to comment Share on other sites More sharing options...

Schurkey Posted March 15, 2014 Report Share Posted March 15, 2014 (edited) Ehhh...maybe not. I was running my '92 Lumina Euro 3.4 (4L60E) hard--passing via WFO downshifts, holding 80 mph on a secondary highway. I was driving hard enough to be borderline abuse. Eventually I'd whack the throttle in fourth gear, and it would downshift into "neutral" instead of third. I could rev the engine, and the car was just coasting. Eventually it'd hit second gear, and be fine until I'd kickdown from fourth again. I'm thinking that the trans was overheated. It acted up multiple times that day...and never again afterward. I've had that car for 10+ years after that day, and the trans shifts fine. 'Course I haven't tried to beat it as hard, either. Because the trans to this day hasn't failed, I have no real answer to why I was getting false neutrals. One trans shop suggested overtheated shift solenoids. I have seen auto trans act the same way when a one-way clutch doesn't hold under heavy torque--but I've never had a slipping one-way clutch act normal for years thereafter.
