Im putting a built TH-350 behind my 406 instead of the R4 cause I dont need OD, for a trailer queen. It will be with a 3500+ convertor. Prety strong set up

My delima is that i bought the tranny already for the build-up, but I got one that has the MV-4 code I think. I bought a book and it says that its a TCC convertor tranny. 3rd gear only I think. But I have no use or desire for lock-up. Plus all the high end buildup kits in Summit, say non-lockup only.

What Im wondering is, can I just buy a regular convertor, and a normal non-lock up rebuild kit and it will work, do I have to have modifications done to the tranny for it to work with a non-lockup convertor? Or do I just need to scrap this one and get another one?

 

i think you should give me your car jeremy... she hates you anyway.

 

You will need to get a NON lockup case to make it work. Which I personally recommend.

Q

 

Theres nothing I can do? Because I know you can modify the lock-up R4s to be non lock-up.

 

ACTUALLY the Lock-up would be nice for extra MPH on the top end.

Either way you can convert that one to non-lock-up.

The easiest way to tell if you have a lock-up unit if there is a electrical plug in on the driver side of the trans. second is the a small smooth section sticking out of the input shaft past the splines.

Good luck!

 

I already know it is lock-up. The case identification matches, and it has the computer plug. What I need to know is how to get rid of it. I wouldnt think it would be that useful, and a high performance rebuild would cost alot more with lock-up I would imagine.

 

ok??

The only thing that cost more is the Converter.

Every thing else cost about the same? Only thing that could toss a curve at you is if the input shaft is toast?

every basic part in a TH350 and a TH350C is the same save for the case, input, converter and extra VB for lock-up.

TransGo has a nice HP shift kit for them now also.

I see no reason not to use what you have unless you just do not want lock-up?

As I stated you can convert the one you have at an extra cost to stanard TH350 by changing the pump, input shaft and using a Supirior VB kit.

Also TH350C units usually have more bearings in them using less HP to run them.

In the end it is your choice. I am just offering options to the un-known and solutions to your problem

 

In all the catalogs Ive looked in Ive never seen a serious race ready rebuild kit, or 3500+ stall equipped for lock-up.

It just seems like it would be more beneficial to get rid of it.

Do you have links to someone who would sell the components, so I can compare prices?

If not does anybod know the actual process for getting rid of it? What has to be done?

 

I TOLD YOU, YOU NO TELL ME DAMN RIGHT

 

What is the benefit of having it non lockup? I know a lot of guys who set their tranny in 4l60e cars to lockup at midway through 3rd gear and WOT...usually they see a couple mph better in trap speed. It would seem a non lockup would just create more heat and a couple hp loss form the "slipping" of the non lockup converter.
