We wish we were able to answer general technical questions, but the sheer volume of mail we get requires that we focus only on our customers and prospective customers to whom we have a duty.
We focus generally on GM powertrain swaps into Jeeps, and with some expertise in classic Ford swaps into Jeeps, and some limited classic Dodge swaps into Jeeps, and other products as outlined in our Catalog. We are not likely able to help outside of this.
If you are exchanging parts from Jeeps to Jeeps, consider the truism that "the hardest parts to swap into Jeeps are Jeep parts" and that we probably don't have the answer to help.
Take an entertained moment and scan our Mythology vs. Actual Observances article. If one could condense four decades of Jeep conversion sense into one short article, then we think we've done it.
It is most helpful to us for you to let us know as many relevant details about your Jeep and project as possible. Tire size and axle ratio (actual or intended, to the best of your knowledge), anticipated use or style of driving (trails? street? rocks? racing? all the above?) can be very useful.
Existing customers may request that product instructions be sent to them. Please have your invoice number and contact your salesman directly, or contact us through our phone system for express support.
Any other requests for instructions will be passed over.
When responding back and forth with us, keep our previous conversations intact. A few bytes of text are cheap yet informative.
If you are mailing from an account that may have been implicated as a source of spam, it may not make it to us. If you've not heard from us in a few short days, you may wish to resend from an alternate account.
Note that our replies occasionally bounce back from certain mail services or those with full mailboxes. Hotmail, AOL and a few others have been problematic in some instances.
Information requests for vehicles other than Jeeps are prioritized on our knowlege of them. Where our focus is so heavily on Jeeps, we will probably not have any helpful information about swaps in other vehicles.
A handful of supreme transmissions have risen to the top of Jeepers' lists. The following gearboxes rank among the most requested and constitute one of the greatest upgrades one can make to a Jeep.
Sourced from GM trucks. Has the deepest first gear, is compact and is compatible between many engines and transfer cases.
Sourced from Ford & Dodge trucks, this strong, innovative transmission is a prime candidate for many Jeeps.
Sourced from GM trucks, the SM465 is extremely strong and refined, and is one of the top conversion transmissions being installed.
Sourced from Ford, Jeep and IH trucks, the T18 and T19 are conversion legends and always offer great service.
Sourced from GM and Dodge trucks, the NV4500 features overdrive. It is a more challenging installation, but very viable in some scenarios.
The legendary T90 three-speed can be married, in simple fashion, to the Dana 20.
As found in CJs, the medium-duty T176 is a good four-speed to install into a Dana 18 or Dana 20 equipped Jeep, where a deep first gear is not required.
As found in many Jeeps, the AX15 is a strong, overdriven five-speed that can be retrofitted into Jeeps that have the Dana 18, 20 & 300 transfer cases.
The NV3550 is a tough, overdriven five-speed and can be retrofitted into some Jeeps that have the Dana 18, 20 & 300 transfer cases.
The T5 offers overdrive for light-duty early Jeep applications that have the Dana 18 or Dana 20 transfer cases.
As found in Jeeps behind the 2.5L, the AX5 can be adapted to the Jeep Dana 300.
As sourced from GM vehicles, the TH350 can be installed into just about any Jeep, and offers great, reliable service for street and trail.
As found in GM & Jeep vehicles, the TH400 is the Big Dog, and offers the strongest possible automatic conversion available.
As sourced from GM vehicles, the overdriven 700R4 is a prime conversion transmission for CJ7 and longer Jeeps.
As sourced from GM Gen. III vehicles, the 4L60E is the pinnacle of strength and refinement in and overdriven automatic.
As sourced from GM Gen. I-III vehicles, the 4L80E is the takes everything awesome about the TH400, and adds overdrive and a lock-up converter to it.
As sourced from GM Gen. IV vehicles, the 6L80 is the best-of-breed six-speed carrying GM into a new era.
The AW4 is found in Jeeps behind the 4.0L engine, and can be installed into longer Jeeps against the Dana or FSJ New Process transfer cases.
For mounting a Dana 18 or 20 independently from the transmission via a short driveshaft.
