Peaches Jeep '86 - Tranny Replacement/Torque Converter ?

Peaches clutch went and I need to replace it but I have been talking to her about an automatic trans.

She has a T-176 in there now w/a little over 100k bolted up to a 258. Since she is not getting any younger (don't tell her I said that) I would like to put a auto in her CJ7.

1. TF-999. I know it is a three speed but she can not have a tranny that requires a lift to make it work.

2. Not sure what torque converter to get with her 258?

Any recommendations on the T-converter and if I am missing something on the tranny?

Thanks,
Jim

Cj's came stock with 999. Should not need lift. Stock converter should do it ok

Agreed-thank you.

I will probably have to order a T-converter.

What is the stock range and also, what would be the next step up from stock?

Note: the engine is stock/2bbl

I'm not sure on that. Tranny shop would be a good source for that info.

TF999 was stock on 80-UP Cj's. You're thinking of the TF727 that requires a lift.

I'm going to have to get my Torque Converter rebuilt or pick up a new one when I get ready to swap my TF999 in.

You'll need new driveshafts (can also have your modified, OR get used driveshafts from another CJ. T5 length are the same as TF999 IIRC), transmission with adapter to go to your Dana 300, either a floor shifter or automatic column with shift linkage. If you go column shift you'll need a new tunnel cover for the tranny hump. Kickdown linkage to carb or lokar cable. If you want it to look right, an automatic brake pedal is nice too.

Best bet is to find an automatic CJ from 80-86 that you can swap everything out of.

Rudy has kits available too but he's quite a ways away from you. I've bought other parts from him in the past and he is a great guy and very honest.

Thank you.

I would like to go Lokar and floor Lokar shifter that looks like a stick.

Might have to get power brakes to.

That lokar cable is awesome and is easy to install.

I used one when I did my 4.0 swap.

Yes they are.

I installed three (Jr's Ashley's & my 360) and they feel great.

I'll bet the stall speed on the TC was around 12/1300 rpm.

No problem Jim. The man I trust with tranny questions also told me that "RV's" , trucks pulling trailers and the like , would use a 18/1900 rpm stall.

It's my basic understanding that, the reason for the higher stall speed is to get the engine up closer to the HP/torque usable range of the engine. This is when Accelerating from a stop.

And that's about it for my knowledge on TC's.

It wouldn't hurt to google "what is torque converter stall speed"

This should get you started in the right direction.

More good reading.

This info is the way I thought it was, not being a expert, and to insure no mistakes. I added the links.
