Can you replace a 5 speed manual transmission you a 1999 Dodge Ram with a 6 speed manual transmission?

Answer 1

AnswerThe only way to replace the 5 with a 6 is very complicated, 1st you have to aquire both trans, then you will have to take a "plane depth horizontal band saw" and cut off the first 3" s of each bell housing. NOW you must produce a perfect weld and attach the 6speeds bell housing to the 5speeds bolt flange. If the weld isn't perfect and 110% level the pilot and throw out bearing will not line up. Next you will need an ossiliscope and a hi-tech certified computer programmer to adjust the new 6Speeds sensors to the existing ecu..

now for the hard part, you musr cut weld and fab in the new 6speeds cross member to hold the torque and weight changes.

weld up th old cross member holes, allign and drill the new ones alling with a steel saft retainer. " a peice of angle iron next to it to reduce stress on the bolts. after all that u may gain 20mph on your top speed and about 15 lbs tq in 1st and 2nd.... and losts more shifts

You won't gain any top end speed, the 6th gear is located between the 3rd and 4th gear in a 5 speed transmission.
