Thread: Severe Drivetrain issue

Tweet

I have a 1982 El Camino with a 305 on a th 350 transmission. I put some trick flow 23 degree heads on it, an edelbrock eps intake and performer carb. I got it all timed and running and took it for a drive things went well. But then I decided to see what it could do i took off and brought the rpms up to about 4000 before the tranny w/ shift kit slammed into second gear it grabbed for a second then every thing went out. It was like I put it in neutral. so i pulled over and stopped I no longer have 1st,2nd,3rd, or reverse. Would this be my torque converter or possibly the tranny pump or what?

yep, sounds like the planetary gear to me., pump could have broke also if you have no working gears.

what they said, but I'd at least put it in gear and look to see if the drive shaft is turning. could have broke somthing in the diff.

no turning on the drive shaft, if the i replace the pump and or planetary gear will it work

Tearing it down would give you that answer but useualy it will be more?????

Was that the first run with the shift kit too? Because it could be a valve body problem, something assembled wrong or stuck. A 305 shouldn't hurt a healthy T350, especially at 4 grand.

There are more things that can go wrong, from broken pump or planetary to small things such as a blown out retention ring in the pump which would bypass all your oil and leave you with no gears.
I'm not 100% sure about this for a 350, but it counts for a 700 trans: There's also a small retention ring on the inner end of the output shaft. Often when you take it off and put it back on it doesn't fit properly, many people don't use a new one... But if that dislodges due to too high pressures your output shaft could slip out of your sungear shell and disconnect everything, especially if your shiftkit is very aggressive it will turn up your pressure so high that you can burst things out...
UC, it could be virtually anything. Your best bet is to pull it apart and have a look, mostly if you have no gears at all left suddenly you'll see what's broken the moment you look into the gadget
Hope I could help,

PS: A torque converter won't brake like that, bets are it's the trans. IF your converter broke to leave you with NO gears, then your vehicle would seriously vibrate even at idle because of bits of turbine flying around inside it(and I mean really seriously).
