As such there are a number of possibilities that can be had when a 5speed is desired: #1. Novak Enterprises: Adapter plate for AX15 to GM 4-speed bellhousing. Connects all except NV3550 to same. #2. 94-95 Dakota 2.5L bellhousing: Connects all to any K car based 2.2L-2.5L L4 in a RWD application. #3. 96-00 Dakota 2.5L bellhousing: Connects all to any Jeep 2.5L L4. Because of it's GM 60 degree V6 inherited bolt pattern, also works with any Buick FWD V6 and supercharged V6, any Chevrolet 2.8/3.1/3.4 V6, any Cadillac 4.1/4.5/4.9 V8 and with a minor modification, any Olds Aurora DOHC V8 and Cadillac DOHC Northstar V8. Also bolts to any Isuzu 3.2\3.5 DOHC V6. #4. 88-99 Jeep 4.0L L6 bellhousing: Connects all to any AMC 290/304/343/360/390/401 V8 and any 72 and later 232 L6 and 258 L6. #5. 94-99 Dakota 3.9L V6 Bellhousing: Connects all to any 3.9L V6 and any 273/318/340/360 V8. #6. 96-04 Toyota Tacoma 3.4L V6. #7. 86.5-92 7M-GTE Not shown: 01-03 Jeep Liberty 3.7L V6 bellhousing: Connects all to any 3.7L V6, 4.7L V8 and 5.7L Hemi V8. Isuzu Trooper 3.5 V6 AR5 bellhousing: Connects all to any Isuzu 3.2\3.5 V6 04 Chevy Colorado\ GMC Canyon MA5 bellhousing: Connects all to any 2.8L L4, 3.5L L5 and 4.2L L6 Aftermarket: Advance Adapters: Bellhousing for AX15 to Chevrolet-Buick-Olds-Pontiac V8 and Buick V6. Connects all to same. Advance Adapters: Adapter plate for AX15 to Ford bellhousing. Connects all to same. Also they have a plate for the NV3550 to do the same. Suzuki Only Supply: Adapter plate to bolt R series to Suzuki 1.3\1.6. Further info: Jeep AX5, Toyota G52, G58, W55, W56, W57 and W58 5-speeds all share a common face pattern on the case. As such, any 88-99 Jeep 2.5L bellhousing (NOT Dakota) will bolt a Toyota W series transmission to a 60 degree GM bolt pattern. Aftermarket: Advance Adapters makes a bellhousing to bolt a W series Toyota trans to a Chevy-Buick-Olds-Pontiac block. Northwest Off Road: Bellhousing to bolt W series to Ford 5.0. Suzuki Only Supply: Adapter plate to bolt W series to Suzuki 1.3\1.6. NOTE: Input shafts lengths vary. Pre 1995 R150\R151 = 6.5" 1995 up Toyota R series = 7.5" AX15 = 7.5" 87-92 Turbo Supra R154 = 7.25" AR5 = ? MA5 = ? NV3550 = 7.5" AX5 = 7.5" Toyota W series = 6.5" Advance Adapters makes an extra long pilot bearing when using a shorter input shaft tranny with a bellhousing that had a longer one. Obviously you can't put the longer input trans into a bell that had a shorter one. Front bearing covers are interchangeable between the Toyota R series, AX15, MA5 and AR5. NV3550, AX5 and W series are not interchangeable. So... there's no shortage of parts for these gearboxes. Any good shop can rebuild them and they are still not that expensive.

The one you use depends on which side the starter is on...

The R154 input shaft is longer, and, with the proper spacing CAN be used in the AX15 bellhousings. Posts: 16 Location: Some further information from Marlin "Crawler" Czajkowski on the Toyota R series and the AX15. Online: 14 h 19 m 59 s This info does NOT apply to the NV3550. "Parts are interchangeable between these trannys. Inputs, output shafts, front nose cone, and rear housing are different but generally can be interchanged if you stay with in the family. There are three "R" families; 86-91 early, simple, common, heavy design 92-95 upgraded syncrows, hubs, shift rods and linkage, smaller bearings, lighter gears 96-newer greater helix angles, upgraded syncrows, lighter bolts, reverse brake The Jeep 86-00' AX15 would use the same bearings, syncrows, and gears within the same family as the Toyota boxes. I am not sure of the Isuzu production years, but would also be the same. Remember that only the 86-87' 4x4 R151F 22R Turbo got the 4.31 1st gear. 2x4 22R Turbos, got the 3.83 1st, along with all other 4x4 R transmissions --Toyota 3.0, 3.4 V6, Jeeps, and Isuzu's. The lowest geared R is the 5.15 1st gear found in the R452 imported trans which also uses the same bearings, and syncrows. The Jeep AX15 has a 10 spline American style input with a 5/8" pilot. I am currently converting a Jeep AX5 to a Toyota t-case I have never had to opportunity to upgrade an AX15. This can be done but only to a 86-91 AX15. The longer coarse spline input and Jeep nose cone will swap right in. The AX15 bellhousing will also bolt up to the front of the R151F since both front housings are the same! I send both Toyota and Jeep shafts to my drive line shop and have them put together."

It may be used in a Toyota application and can bolt up any GM 60 degree engine (3.4/3.1/2.8 Chevy V6, Buick 3800 V6, Isuzu 3.2/3.5 V6, etc....) to the Toyota G series and W series tranismissions. Shown is the Toyota W58 out of a Supra with the AX5 bellhousing. For this to work, you'd need the thick (heavy) flywheel from an S10 truck or Camaro/Firebird. It places the clutch disk back far enough to engage the splines on the short W series input shaft.
