Turbo Hydro Matic ????

[greygoose]

Does anyone know what the turbo hydro matics came with 2 or 3 speeds ? this is mine and I need some help figuring out what speed it is.(4m49cc)Can anyone look this up for me...Thanks

[DREAMS OF A 67]

I think powerglide was the only two speed.

[texanidiot25]

Power glide is the only 2 speed auto GM has. TH350 and 400 are both 3 speeds.

You don't say what year your truck is or whether it's stock. That may have some bearing on the type of tranny you have. As texanidiot says, power glides were the only 2 speeds.

Here's a site that lists most of the transmissions that GM made in case it's a newer one or came from a car.

Look at the pan gasket. It's the easiest way to tell.

on a truck, M49 can be a TH350, or a TH400

Thanks guys I guess it would help to know what yr it's in.lol It's in a 68 c10 custom that's hooked up to a 327

i can tell you that the last production for the 2-speed was 66. no 67-72's came with a powerglide. the 'glide was produced in cast iron until 63 & in aluminum til 66. then along came the 350 & 400.

There is a small handful of guys here with powerglides from the factory. Another oddball set of these generation trucks..

My '71 came with a 2 speed glide from the fact. & my dad had a '69 that also came with a fact 2 speed powerglide.

[Longhorn Man]

yep, they were offered untill 71 or 72.
The TH350 wasn't offered till 69 if i remember corect... that would leave Th400 on that M49 option... we are only assuming that's whats under there now though.

Here's a good reference for oil pan identification. http://www.technicalvideos.com/ident...smission.phtml

Not to hijack your thread but, are 700R4's 4-speeds?

[Longhorn Man]

yes, 700 R4 and 200 4R are both 4 speed automatic overdrives

Mine doesn't have a kick down cable(shift cable) or anything,so I was wishing that it was a P.G. or did the early one's come without a kick down cable(shift cable).Thanks 68gmsee & fixitup for the links,I'll have to get under it tomorrow and see what the pan loos like.And thanks to you guys as well for the info.....

[mr48chev]

My 67 had a Powerglide in it.

[lofly'a]

i stand corrected, never seen one in a car or truck after 66 (and yes i am old enough to remember those days). thought trucks followed the same suit. in any case they (powerglides) were the ones i least liked. boring to drive on the street

Well what does the shift indicator on your column say?

Is it PRND21 or just PRNDL (I think that's the powerglide)..

The SPID and VIN can help ID the tranny too..

[Longhorn Man]

the VIN won't help[ one bit on ID'ing a tranny
If there is no kick down, then it is a TH400

My TH400 has an electric kick down not sure if the power slide or the 350 had that check if it has a wire going to it it almost looks like an oil press sending unit but the best way is to id the pan gasket shape.
