    The dipstick on my TH350 is pushed out about 2" every time I open my hood. Does anyone know what causes this? I'm not having any other problems other than it takes awhile to go into reverse after I shift the lever.

    are you leaking tranny oil, if you are than you might want to check the oil level, same thing happened to me once I didn't notice that I was leaking tranny oil and when I shifted in reverse it was taking about 30 seconds to shift I thought my tranny was gone when I checked the oil level it was too low pour some oil and the problem was gone, hope your problem is similar and you wont need a new tranny good luck.

    keep blazin !!!

    You may want to check your diff. vent. I had a 350 that did the same thing. But it only did it when racing. It pissed off the officials on the track. There was always a line of tranny flid about 1/3 of the way down the 1/4. That and the side road. If I remember correctly, when I had the trans rebuilt, I put in a lower stall converter. I don't remember the numbers, that and a short term fix was to duct tape the damn thing in.

    I bet only happens after your on the throttle doesn't it?!?!?!?!

    Sounds like the vent is plugged and it has to vent somewhere so it's poping the dip stick. There is a vent on the driveside near the top almost directly in line with the shift linkage. It may be that when you got rebuilt the fool RTV'd the hole closed. It is supose to have a little cap do hicky like the vents on the axles. Mine was busted when I rebuilt mine and I found some plastic hose barbs in the help section that fit snug. I used some gasket sealent to hold it in and ran a vent hose up the fire wall. I then took a cheap gas filter as an end so that it could breath but keep the dust down.
