I have a T350 automatic transmission. The last couple of years when I've pulled the pan to replace the filter, I've noticed some metal filings in the bottom of the pan. Is this normal, or should I be concerned? I also notice that when I put the car in gear, it seems to take a moment for it to get in gear. Does anyone have any recommendations on what I can add to the transmission fluid to keep it from apparently slipping?

Any advice is appreciated!

How do you guys keep an automatic from downshifting when you come off a corner?

I know i am a dumb *** . But i do not know the answer yet. Just trying to learn.

Thanks

some guys run a manual valve body, some run in first gear. but hopefully you are carrying enough speed so you don't have to worry about it

Hey Rogracer,Are you sure you have the right dipstick and tube in your trans?It sounds like your low on fluid,About the pan and filter it is normal to see some **** in there.

I ran Lucas in mine.

If its all stock, remove the cable and plug the vac lines. Then you still HAVE to manually shift it from 1st to 2nd after you get to about 3000 RPMs, then it will stay in 2nd. I was just putting mine in 2nd at take off but, it would let it shift too much.

not a dumb question at all. I assume your running 2nd or third gear. unhook your kickdown cable.... should cure the problem

If its taking a while to kick into gear, its getting tired. Mine has been doing that also for the last two or three years : ) They make inline tranny filters, get the magnetic one, it will clean alot of that gunk outta there...

I was wondering about the torque converter. Most drag racing and street rod torque converter allow you to accelerate better that OEM. However they don't do much for you when it comes to engine braking. For example, I have a TH350 and run it in 2nd gear and have had no engine braking because of the OEM converter. Are there converters available to allow me to engine brake in 2nd gear?

Do any of you know how to keep a TH350 in first gear without shifting into second without a manual valve body?(stock tranny)We run first gear here sometimes it will shift to second on me.

All i did to mine was cut off the kick down cable and plug if off so fluid doesnt leak out and plug off the vac line to the module and it never shifts out of first. Other than that its a stock trans.

Hey racer17 i have built this camaro that i am selling and it has a t-350 we have 3.73 in the rear and was thinking that 2nd would be the gear to run in. Are all turbo 350 do they have the same second gear ratio. If so shoot me my final at the wheels in second with 3.73 Thanks steve

It would be a 5.67,1st gear multiply by 2.52,2nd gear multiply by 1.52,3rd gear is 1 to 1.
