I have a 2001 2.4 liter 2wd with the automatic transmission. The door sill sticker says it is a A44D transmission as you can see in the first pic. I believe this transmission was used 2001-2004 and maybe 2000. I bought the shop manuals. Open the cover and it says the automatic transmission manual has a publication number of RM387U, for a A43D transmission. Only I have a A44D transmission. I thought this was a typo by Toyota But then I flipped through the shop manual and there is a small section for the A44D transmission I have, which says that if you need more info to refer to the A43D transmission manual with a publication number of RM387U.

• 2004 Toyota Tacoma Repair Manual Free
• 2004 Toyota Tacoma Jack Handle

Pics 4 and 5. So it does not look like there is a typo unless it was repeated more than once.

On the Toyota website it also says I need publication number RM387 for the A43D transmission, despite the fact I have a A44D transmission. Wiki says that I should have the A43D but I believe this is a mistake. Wiki also says the A44D was use on the 1989-1991 4Runner. Does anyone have the transmission manual for a 2001-2004? I have a 2004 Tacoma 2.4L - A44D - and the hard copy factory service manual.

Yes - this is confusing. You have an A44D as indicated in the lower right hand corner of the tag in the drivers side door.

The A44D has a 14 bolt pan. The A340E/A340F have a 19 bolt pan. The later were used on the 2.7 engine if I'm not mistaken. Here's my take on the ref.

To the A43D in the publication you have. All of this is based on a lot of WEB research. I see this also in the 2003/2004 FSMs. The A43D and A44D are in many respects the same 'mechanically'. The A43D performs shift control by way of the throttle plate position.

The A44D uses electronic control to accomplish shifting. Also - transmission filters. Many dealer parts people have told me these vehicles(and other modern Toyotas) use a mesh type filter that is washable and reusable. Look online for a filter for a 2004 Tacoma with a 2.4 liter engine and you will see the same type of filter that's available in just about any car.

Metal housing with a fiber content to strain the fluid. This type of filter would hardly be washable/reusable? Also - the filters for the A44D/A340E/A340F are different. A44D - 5 BOLT FILTER A340E - 3 BOLT FILTER A340F - 4 BOLT FILTER For a 2004(and maybe 2001-2003) with a 2.4l engine- appears to be one of the few with the correct filter for a 14 bolt pan.

I'm basing this on my locale where the major mass marketers are AZ, O'Reilley's; Advance Auto Parts. Some of you have those and other options. All of the ones I see online for a 19 bolt pan are for the A340F. I have not seen one for the A340E. Not only are the Toyota's parts people confused, but so are the online transmission providers. Many show the 2001-2004 Tacoma as being equipped with an A43D. Again, the tag on the door tells the story as well as the pan bolt count.

In this forums sticky you will find electronic FSMs for 2001-2004 Tacoma's. 39 meg zip file. The manual is actually a 2003 Tacoma FSM. The 'online' version is incomplete.

This post is old so I will update.

I found RM387U on. Seller had 2 of them. I bought the last one. But what he send me was RM327U. When I contacted the seller he said he made a mistake in the listing as he only had 1 RM387U which had already been shipped to the first buyer. I then went back on ebay and found and bought RM387U.

So now I have 2 manuals. The are both the same as far as I can tell, but notice that the image of the transmission on the covers is different. One manual has 1993 at the top and the other does not, but has Nov. 1993 near the bottom.

One was printed in Oct. 1992 and the other in Nov. Again, as far as I can tell from glancing through the pages, both manuals are the same inside. I did study and compare the 3 pages of specifications in both manuals and they are identical. Both are for the A43D transmission but I guess there is so little difference with the A44D that it does not matter.

Standard oil clearance: 0.005 to 0.011 mm (0.0002 to 0.0004 in.) Maximum oil clearance: 0.025 mm (0.0010 in.) (f) If the oil clearance is greater than the maximum, replace the bushing. If necessary, replace the connecting rod and piston pin as a set. INSPECT CONNECTING ROD (a) Using a rod aligner and feeler gauge, check the connecting rod alignment. (1) Check for bend.

Maximum bend: 0.03 mm (0.0012 in.) per 100 mm (3.94 in.) If the bend is greater than the maximum, replace the connecting rod sub-assembly. (2) Check for twist. Maximum twist: 0.15 mm (0.0059 in.) per 100 mm (3.94 in.) If the twist is greater than the maximum, replace the connecting rod sub-assembly. INSPECT CONNECTING ROD BOLT (a) Using vernier calipers, measure the tension portion diameter of the bolt. Standard diameter: 7.2 to 7.3 mm (0.283 to 0.287 in.) Minimum diameter: 7.0 mm (0.276 in.) If the diameter is less than the minimum, replace the bolt.

EM–146 2TR-FE ENGINE MECHANICAL – ENGINE UNIT EM 48. INSPECT CRANKSHAFT (a) Inspect for circle runout. (1) Place the crankshaft on V-blocks. (2) Using a dial indicator, measure the circle runout at the center journal. Maximum circle runout: 0.03 mm (0.0012 in.) If the circle runout is greater than the maximum, replace the crankshaft.

(b) Inspect the main journals. (1) Using a micrometer, measure the diameter of each main journal. Standard journal diameter: If the diameter is not as specified, check the oil clearance (see step 30). If necessary, replace the crankshaft. (2) Check each main journal for taper and out-of- round as shown in the illustration. Maximum taper and out-of-round: 0.005 mm (0.0002 in.) If the taper and out-of-round is greater than the maximum, replace the crankshaft. (c) Inspect the crank pin.

(1) Using a micrometer, measure the diameter of each crank pin. Diameter: 52.989 to 53.002 mm (2.0862 to 2.0867 in.) If the diameter is not as specified, check the oil clearance (see step 2). If necessary, replace the crankshaft. (2) Check each crank pin for taper and out-of- round as shown in the illustration.

Maximum taper and out-of-round: 0.003 mm (0.0001 in.) If the taper and out-of-round is greater than the maximum, replace the crankshaft. INSPECT CRANKSHAFT OIL CLEARANCE HINT:. Keep the lower bearings and crankshaft bearing caps together. Arrange the thrust washers in the correct order. Keep the upper crankshaft bearings and upper thrust washers together with the cylinder block.

(a) Clean each main journal and bearing. (b) Check each main journal and bearing for pitting and scratches. If the journal or bearing is damaged, replace the bearing. (c) Place the crankshaft on the cylinder block. G037368E01 No.1 No.2 No.3 No.4 No.5 G037369E02 No.3 journal 59.981 to 59.994 mm (2.3615 to 2.3620 in.)

(e) Install the 5 crankshaft bearing caps in their proper locations. (f) Install the 5 crankshaft bearing caps with the 10 bolts (see step 49). NOTICE: Do not turn the crankshaft. (g) Remove the 10 bolts and 5 crankshaft bearing caps. (h) Measure the Plastigage at its widest point. Standard oil clearance Maximum oil clearance: 0.10 mm (0.0039 in.) If the oil clearance is greater than the maximum, replace the crankshaft bearing. HINT:.

If replacing the cylinder block, measure the bearing standard clearance. If replacing a bearing, first check the number on the cylinder block for the bearing's respective journal.

Then replace the bearing with one that has the same number. Each bearing's standard thickness is indicated by a 1, 2 or 3 mark on its surface.
