Precision of New Hampton Hemi Tourque Converter

I was set on purchasing a Suncoast converter. The more I read and thought about it, the more I believed the Suncoast converter is overkill for the CRD.......even for me. I considered using the Dacco R36LS. I did some internet research/reading and found good and not so good reviews. I decided I wanted something a little better.

I purchased a Precision of New Hampton Torque Converter from a local transmission shop. I spoke to a Precision of New Hampton Torque Converter technician on the phone and told him I was interested in using the 5453LS in a Liberty CRD. I told him I had a tune and gave him the GDE hot tune numbers. His response was: "Let me build a converter for you." He recommended the 5453LSA converter. The 5453LS is a low stall converter for the 545rfwe that it is usually used in hemi truck applications. According to the technician, the 5453LSA is a heavier duty version of the 5453LS. The 5453LSA has a 4" hub that is welded to the case around the perimeter of the 4" hub instead of at the base of the hub "tube". He also stated that the lock-up clutch in the 5453LSA converter is more than adequate for the CRD The 5453LS is a reman and is available locally for $190 including the $40 core. The shop would not accept the Jeep converter as a core for the 5453LS. The 5453LSA is a new converter and is available from the same shop for $205 without a core and is it built to order. I should be receiving the converter in 2 - 3 weeks. I attached a link to the Precision of New Hampton website.

I will be interested to know your thoughts about this once you get it. I have just ordered the R36LS for another CRD, and would not have had the lead time to wait anyway on this option. I have really only experienced the shudder on one CRD, Papaindigo's Jeep after the GDE turbo was installed. From reading the limits on the factory converter that was originally selected, I cannot believe the stupidity of Chrysler. To choose a converter that was so close to its own torque limit in stock form, to say nothing about if any power is added... What WERE they thinking? You don't spec a 10 lb sack when you have to move 10 lbs of crap... You spec a 15 lb sack!

Chrysler. We might do it wrong, but we'll happily do it wrong again and again!

I had a custom Precision TC made for my 85 F250 when I had the trans built. It was nearly $700 bucks but its preformed wonderfully, I will follow your path I assume.

Minor point of clarity on my shudder that geordi mentioned. Oh we definitely had shudder but it was right after installing the GDE stage II turbo while I still had the stock torque converter and only occurred when we pulled out onto the main road from geordi's and I stuffed the go pedal. I drove all the way back to Tally, drove around town for about a month, and then drove to Suncoast for them to install their torque converter. During that time I just used a light touch on the go pedal and had zero shudder problems.

The Suncoast is probably overkill, the Euro will do, but it along with the GDE turbo was a retirement present from me to me not to mention I'm pretty close to Suncoast and they did the install with a 2 year warranty.

I didn't think you had even gotten halfway to the floor before it overpowered the converter though - 40mph and instantaneous shudder.

I've driven a couple other CRDs with Keith's turbo in them, as well as some of the freshly installed timing belts. What I see as the benefits to Keith's turbo are the reduced spool time for a non-power-launch (takes off about .5 to .7 seconds of lag) if you just go right to the floor from a dead stop... But if you do even a modest type of power launch, I don't think you will be able to keep the tires from breaking loose on dry pavement. WOW what a lot of power.

The other benefits are a larger unit so it is not as close to its own operational limits at full boost as the stock unit is. Boost spikes on the stock turbo can easily reach the max RPM that it should ever spin... If it goes above 27psi in a spike, you are risking the turbo destroying itself. Keith's turbo fixes this.

I'm not crazy about the price point, it is a big bite... but for the limited number of kits that he will sell versus the development costs, I think it is more than fair and a good value if you have the cash laying around. If I had the cash laying around, I'd buy one for sure. The benefits of the Suncoast converter are less clear, over a converter that is just built to handle a much larger engine and more torque. That is all the TC really needs to be able to do.
