3 speed auto Trans mods all in one place

[turbovanman²]

Company in New Brunswick made a few billet converters for a guy, it slipped badly, last I heard, they were trying to fix it.

[Ondonti]

Saw on srtforums that Red Sled is still having converter problems. He recently ordered 3 billet converters, each from a different company. Trying to find one that achieves the high stall he wants without excess slipping. I believe this is after having exhausted the resources of our normal go to guys to satisfy what he wants.

[joesf]

He is in a while different class that guy is trying to run low 7s

[Kryp2nitE]

Again several

What does a good billet converter cost for the 413?

[joesf]

Not sure never see a price listed so my guess is too much for me

[turbovanman²]

I paid $500 for my HUgh's LU converter and killed it in a few months, have to get it back for warranty, it has one year and its almost up,

[joesf]

The converter in general or just during lockup

What does a good billet converter cost for the 413?

Don't know about billet, but my 9" ATI was $700...

[turbovanman²]

Both, the LU stopped working then it wouldn't stall at the line then it started really slipping on the highway.

[joesf]

I know you DD it but have you ever tried a non lock up

[turbovanman²]

I switched to a LU a few years ago, couldn't stand the high highway rpm, the LU fix's it and makes it a nicer highway cruiser.

[joesf]

Yeah I figured that's why you went to a LU, how did the nonLU compare in longevity

[Vigo]

If you arent trying to lock up the torque converter clutch under high loads, it shouldnt have any effect on the longevity of the rest of the converter.

I'm building an A413 from a non-Lock-Up to a Lock-Up. I've never done this before. I've only built a non-LU and stayed non-LU or a LU and stayed LU. All I need to convert to a LU is the valve body with solenoid (I got the whole valve body because I didn't know what valves and springs are needed), the input shaft, drill the case for the solenoid, and the LU converter. Correct? I just want to double check before I start putting this thing together.

I figured I'd ask this here instead of starting another thread to try to keep it all in one place so if someone wants to look it up later it'll be easy to find.

Since the input shaft is part of a clutch drum, it's worth pointing out that you should always try to get the clutch drum with the higher snap ring groove so you can fit a larger clutch pack. That might rule out all the TBI lockup trans as good input shaft donors.

That is false. The input shaft is removable. It's held in with a snap ring. I've had to remove a worn out input shaft to keep my higher snap-ring groove drum in the past. I did get the higher snap-ring groove drum with my LU input shaft for this build.

Maybe I am thinking of RWD only here but is the pump/stator support different between LU and non LU in the FWD unit ?

[Vigo]

Good call. I never separated them when i did it for a living and havent had to build one in several years (mostly because i keep swapping them out for 5spds, like i did to a shelby lancer last month). My memory is very 'use it or lose it', unfortunately.

[Vigo]

Im considering doing a lockup conversion on my 88 Lancer Shelby, so... any more recommendations/clarifications? Does AJs list cover it?

I'd need to re-read the ATSG manual but if you are swapping input shafts to match the converter you also need to swap in the correct pump assembly..there may be another piece you're supposed to swap with it.
