Tranny Advice

[ksjh1316]

Alright I admit I am stupid on this I found a deal on a rebuilt th350 transmission that has a 2200 stall and as the guy put it a stage 1 shift kit placed in it for $400. The question is how will this affect the end preformance I have a newly rebuilt 350 that was estimeted to be at 350 hp and 400 torque. This engine is mildly cammed and running a 650 cfm Eldebrock electric choke carb. Any suggestions appreciated and let me know if the price is right on this trans.

Do you mostly drive on the street? With a 2200 rpm stall converter you're gonna get pretty crappy gas mileage. Plus your trannys gonna run alot hotter. Sounds like a pretty good deal assuming the guy has documentation on the rebuild, or at least receipts for parts.

All street and highway no track for this one. The guy I found it at rebuilds them in his spare time and has built up a supply he wants to unload.

Yeah the tranny sounds like a decent deal but i really wouldnt go with that high of a stall converter for a street truck. Keep in mind the stock one was like 1200 stall.

Buy the trans. and get a different torque converter.

You getting any snow down there? We just got a dusting here in T-Town.

Ya the snow is coming down pretty hard the worst part of it is that every little old lady who hasn't driven since 1979 is on the road right now.

Should I use go back to a factory stall my engine builder seems to liek this combo as he suggested the guy what is the big disadvantage I will see other than MPG

With a 2200 RPM stall when your stopped, say sitting at a light your trans. will "essentially" be in neutral. When you go to take out your engine will rev to 2200 before your truck starts to move. It's a smoothe transition though, not like shifting from neutral into drive. 2200 is not that steep. You will just have to try it and if you don't like it switch it out for a stock.

I've always liked a low stall speed for most applications (I'm not a racer). Fords always seem like they use a higher stall speed in their tranny's and I've never liked the feel of it. Of course, Ford also thought it was a good idea to have the first "drive" on the shifter as a position to start out in SECOND GEAR! Not everybody buries their drive wheels and needs to pull out in second! I wonder how many unknowing Ford drivers (kind of redundant I realize!) have the impression they have a 2 speed tranny! My buddy has an old Lincoln Continental with this "feature". The converter slips so much that on the flats you can't even tell if it starts out in 2nd or 1st. It does raise the tranny temp though...

Biggest disadvantage other than MPG will be temperature. As long as you have less than 350hp, you can pretty much get away with a stock converter. Theres also a couple companies that build converters with 1350-1500 stall that are a little stronger than stock, but they're around $200.
