transmission fluid filters

[grumpyvette]

now in most transmissions theres is a transmission fluid filter inside the transmission oil pan that should be changed along with the fluid at the recommended intervals (30,000-100,000 miles) depends on year of transmission fluid and conditions the cars used under.
these vary in quality but most are very reasonably priced and easy to install once the transmission oil pans removed.
keep in mind many transmission oil pans do not have a fluid drain so you either remove the oil pan or need to install/weld on a drain , bung and bolt drain assembly, or buy the cheap and easy to install but not quite as efficient bolt on verity.
adding a remote transmission filter and USUALLY along with the remote filter an oil cooler for the transmission fluid will usually extend the transmission life span as it tends to lower trans fluid temps and trap and remove some additional contaminants in the trans fluid , and make inspecting the trans fluid condition far easier

Dorman/AutoGrade universal transmission drain plug kit
Price:
$2.99
Part Number: 65241
or
Part Number: 090-086 $29.99

easy to weld on

measure very carefully youll need to mount the transmission cooler in a location that allows clearance for both the cooler and its supply lines and in a location with easy access to outside air flow so the heated air can rapidly be replaced with cooler outside air, for effective heat reduction to the fluid to effectively take place.
ID suggest no smaller than AN#8 line (1/2") size and a 24000 lb weight rated cooler if you have the room to mount one on a serious race application, with a high stall speed torque converter.

Is there something special about the external trans filter like the one shown in the Derale kit, they cost $20 ??? Couldn't you use a engine oil filter for much less.

TRANSMISSION FLUID LINES operate at significantly higher average pressures than most oil pressure in oil coolers and transmission fluid filters are built a bit more robust as a result, so at least in theory they are not interchangeable,from info I see posted its possible in some applications to see 130 psi line pressure with some transmissions in a few applications, that being said,

as far as I know any quality oil filter could be used that fits, Ive sure used oil filters in the past,in fact Ive used remote mount oil filter adapters on almost every remote transmission filter Ive ever used, maybe Ive just been very lucky but in 30 plus years Ive yet to have issues.
mostly the longer versions as I usually mount them near to the oil cooler, obviously you need to have the room and the filter mount and threads must match, so verify the thread pitch and seal diam before buying a filter for your remote mount oil filter adapter

after careful measuring most hydraulic shops can provide custom professionally made high pressure oil lines, don,t even think about use of nylon braid/ rubber reinforced FUEL LINE, or common auto parts store heater hose

Tube: Black. Specifically compounded for temperature and chemical resistance (CPE – Type J)*.

Reinforcement: Two braids of high tensile steel wire.

Cover: Black. Specifically compounded for temperature and chemical resistance (CPE – Type J)*.

Temperature Range: Petroleum-base fluids -40°F to +300°F (-40°C to +149°C). Phosphate ester fluids as recommended by the fluid manufacturer, but within a range of -40°F to +212°F (-40°C to +100°C).

Internally the transmission sees much higher pressures...above 200 psi. But since the the lines are much bigger than passages in the transmission and a filter is by design not to be restrictive, then I suspect the pressures within the remote filter and lines would NOT be very high.

I got curious,
I called several transmission cooler manufacturers and asked the tech guys what max line pressures were likely to be, most said the range varies wildly with converter stall speeds, engine rpms , transmission design, cooler used and line sizes, but 60psi-130 psi were possible

Spin-On filters have a Burst Pressure Rating. I found this definition on the Wix Fliter website. Also Moroso published the Burst Rating on their filters, which range from 300 psi to 675 psi. Looks like there is enough of a safety factor there, we should be OK, unless other manufactures vary a great deal from the Moroso example.

just a bit of info
all the tech guys, during the questioning, suggested fluid transmission line (hydraulic oil pressure lines) designed for a MINIMUM of 300F-350F temps and 275psi-350 psi be used on transmission oil coolers, most suggested a 1/2" or AN-8 minimum line size with matched fittings and pressure ratings

Another filter mod for the 200R4 is to use a 700R4 filter requires a deep pan or pan spacer.

The 200R4 feeds from the top of the filter and under hard acceleration fluid cavitates to the back of the pan uncovering the inlet and a drop in pressure. If you must use the 200R4 filter add an extra pint of fluid to ensure the filter can't suck air. I used to fill to the first bend on the dip stick prior to going to a 700R4 filter and deep pan.
You need to insulate the 4th clutch pressure switch terminal with shrink wrap or rubber tubeing.
