1500 5.2 auto no drive

[wil440]

My Brothers new to him 2000 1500 5.2 2wd auto of which he's had for maybe a month and I said it was a good truck (for a 1500) has just this afternoon stopped driving as in no drive forward/reverse any gear nothing but a horrible rattle whenever engine is started, this isn't a real metallic rattle it's more like a metallic rattle that has oil for lube if that makes sense

I towed him very slowly back to our workshop and got it onto the lift, dropped the pan and there is steel fillings in one spot at the front end of the pan slightly to the left side, I think the torque convertor is dead as it's been having a lockup wobble randomly, we changed all the solenoids/sensors etc in the pan 2 weeks ago to address a P1740 (IIRC). it wasn't changing into 3rd, it changed fine after everything replaced in the pan

 

So as I say I'm sure it's the torque convertor, oil is clear, no burnt smell, nothing slipping beforehand, got the starter off and flex plate good although I did think the convertor felt hotter than the rest of the trans but when it did fail he was 40mph down a slight grade so coasting really.

I wasn't prepared to run it on the ramps to test pressures as I feel the trans isn't toast and didn't want to pump steel everywhere

I'm going to pull the trans tomorrow

Am I missing anything ????

I hope it is the torque as a trans rebuild here in the UK is pants at best

In put shaft or stator/pump?

Looks like I get trans experience either way   all good for when mine ~~its itself but at least what you suggest is all at the front

Got it out yesterday and the torque convertor has no splines to drive the input shaft.  Pulled the trans oil pump and the bearing is damaged, seal needs replacing as thats not been put in very good at all and the machined surface that sits in the front clutch has a score in it but the bush in the clutch is fine with no damage at all.

Checked RA and they don't sell a complete pump just parts to repair

Found a trans parts supplier with all the parts to rebuild the pump called Global Transmission Parts so thats all ordered, Rockauto has a convertor so will order that today, going to pick everything up from our workshop and bring it back home so I can turn a bush and seal driver on my lathe

Input shaft is ok, where the input splines locate in the torque convertor has no spines.

Just ordered a good used pump with new bushing and seal installed as I'm not happy with this one as the bush is loose in the cover but I've also got a seal/bush kit and pump gears on order also so I'll see what the new bush is like in the old cover

pictures not too good, I've just had a new mobile/cell phone and I can't use the thing

 

The smaller splines that are blurred you can see that there is no splines until further in where the input shaft doesn't reach

Started the job this morning at 10.00 am fitted a new torque convertor, new bush in the oil pump and a new seal, refitted the box, tested and all is good, box in and running by 3.00pm, finished testing and tidying up around 6.00pm. We have a lift but it is a 2 poster and only 3tonne so we only took the truck up about 2 or  3 ft, we had 2 wheel rims under each front wheel and wheel jacks under the rear, we need a bigger lift as I wouldn't feel comfortable under my truck on that lift or a workshop with a pit

Got a good strong magnet on the pan and we're going to drop it again on Monday as we've got some pan bolts to helicoil, we knew we had some that weren't great anyway everyone here has metric helicoils BUT no one has unc so had to order the helicoil kit, good reason to drop the pan and check for filings.

I'm going to look for a toasted 46re and put a rebuild kit in it to put on the shelf  as I want/need to do my 47re and it will be easier to do one beforehand
