TH 350 help

MYLINRACING · 05-29-2016, 08:01 PM

I run a turbo action 350 with a ATI converter, recently the converter would not flash above 4,000 and it a 5,800 stall converter. So we put the spare converter in which is a 5200 and we have the same issue won't go above 4,000. I find it hard to believe i have two bad converters. Any ideas what the problem could be?

Thanks.

Put a pair of water pump plyers on the stator support and make sure it won't turn.

Stator shaft (big splined tube) is possibly loose. Also you could have another pump problem, or valve body problem. Do you run a transmission cooler?

No Sir, I don't run a cooler

I'm not a sir. Just a guy.

Any other changes before this started?

Checked the basics?

Fluid level?

Ignition sytem?

Fuel system?

Timing?

We have changed just about everything MSD box, coil, fuel pump, fuel reg, Carb, Converter. Trans fluid level looks good and the timing is were it should be. Checked the stator shaft but it is tight. Going to call Turbo Action in the morning and see about a new valve body.
