94 lumina trans slips out of gear

[ztopgun]

Hi
I just got a 1994 chevy lumina euro, when I drive it ,after 1 minute it slips out of gear, if I shut it off and restart it it goes good for another minute or so,and I have to do the same thing again,Is there a sensor that could be causing this ? or is thetranny on the way out?
It makes a clicking sound in reverse and when I first take off.
Also the fluid smells burnt, but it looks like a new tranny was just put in it. I drove it 300 miles like this from washington to buffalo. I would get sometimes 2 to 5 miles before i would have to shut it off and restart it.
and then go another 2 to 5 miles. took me a long time to get the car home. any help with this?
Thanks

first start by changing the fluid and filter and maybe an additive like Lucas or something. it's a messy job so get a big pan and a lot of floor dry.

You know, I just thought of something I haven't seen happen in a long time, but I've been thinking about this for a day now. I've seen them do that when the filter isn't installed correctly, being a press fit, if it drops out of place, the pump can't pick up fluid. It can reach it initially, just enough to pressurize the circuit, but as the level in the sump drops, it can't reach it, since the filter is the pickup. Then it slips outta gear. Then, as pressure bleeds off, and fluid returns to the pan, it can reach it again, and it starts over again. If you drop the pan and the filter falls out, or isn't firmly seated in the cavity above it, that was it.

sounds to me like a plugged filter not good
