CJ vs YJ TF999

I am still trying to get a replacement TF999 for my YJ... I found a great deal on a rebuilt 999 from a CJ... are there any differences?

Or how about... are the bolt patterns for transmission bellhousing on the 4.2 and 4.0 the same?

no- not in Cj's and older Yj's until 92.

May need to swap bell housings. I don't remember if the Cj had a hole for the CPS or not.

Everything you need to know about the 999.

Some CJs did have a lock up TC. Mine does (84). I just rebuilt the tranny so I am sure. It is a mechanical lock up though, not electrical. No solenoid.

CJs did not have a hole for a CPS.

I don't currently have a lock up converter in my 91... So the only difference is that there is no hole for the cps? Is there anyway around that other than swapping bellhousings? I wanted to buy this one to try and avoid completely rebuilding one... but if I have to swap everything over to the other bellhousing, kinda eliminates the point.

Okay, so I have heard about this Hensco kit... But I can't find it for sale online anywhere, if I could it is supposedly 370 dollars, and it relocates my cps. I have seen on other sites where people had a bracket and drilled a hole in the bellhousing... called it good.

Can anyone help me locate a hensco kit or tell me about drilling the bellhousing?

Rebuilding the tf999 is just about as simple as it gets.

It's Hesco
Hesco Inc. - High Performance Engine Service

This is the part # you supposedly need HES9199ED but it's not listed on their site. Also it appears to be for 91-03 4.0L. You should give them a call in the morning.

Advance Adapters also has a kit. 91-96 4.0L
716012-C | Engine & Transmission Conversion Adapters - Advance Adapters

I hope that helps you.

on the tf999 there is no 'swap' bellhousings...it's part of the tranny, not bolted on like a manual tranny.

Honestly, it doesn't take much more mechanical knowlege to rebuild one of those trannies than it takes to get one out of the jeep and replace it correctly. Much cheaper, and you have the assurance of everything that needs replaced, was replaced. OR a trans thats been removed is much cheaper to have rebuilt than one they have to take out, call around. All of this is cheaper than buying another one and rigging up a cps.
