I have a 1990 Dodge Dakota P/UAfter I serviced the transmission, I noticed the transmission is shifting different. Maybe a little slippage but I fell the difference. Could it be the fluid I used?I used just regular transmission fluid, is there a special brand I should use for a Dodge?
If you used Dextron fluid rather than ATF+3 or ATF+4, that is your problem. Have the transmission completely flushed (not just dropping the pan) and put ATF + 3 in it. The major cause of transmission failure in MOPAR transmissions is the use of the wrong fluid! Do not drive the truck anywhere but to get the transmission flushed and cross your fingers that it holds together!!
If you mean by regular transmission fluid you used Dexron, that is the wrong fluid. Chrysler products use ATF+ 4. No other kinds are recommended. To get all the old fluid out will require a flush, or change the fluid about 3 times, third time with a new filter.
i've always noticed as soon as you change the fluid its time for a new transmission however if you would have used ATF 4 you would have had a chance, go flush it out and have them put the ATF 4 in. Otherwise it will get worse believe me I've been through 3 dodge transmissions.
