tr6060 vs tr3650

[Metallicats]

Question for the experts,I want to replace my tranny by a tr6060 with a 9" diff with 3.89 ratio(first I look for an auto trans but I have a big deal for the tr6060).Now I'm running the tr3650 with my old 8.8" with 4.10.
Someone tell me if I will see a difference ??? because the gear ratio in the transmission are different,my best e/t are 10.95@136mph and I want to have a better time and mph

I suspect you'll see little difference. Maybe you will have a bit more time in each gear

wow thanks...do you think it's a good replacement ??????

 

[stkjock]

the 6060 is a much better trans than the 3650

also consider getting the new MGW Gen2 shifter - from all I've read the thing is incredible.

It's an excellent replacement. The rear shifter mount gets too much blame for issues with the 3650 imo. The 3650 is a good transmission but the 6060 is so much better with bigger gears, better syncros, and a stronger input shaft. The bigger gears and better syncros make a world of difference in how well the transmission shifts.

I would wait and get the DOB shifter for the 6060. I've seen pics and it's AMAZING

 

[stkjock]

IGDAF what you'd do

Don't take my word, talk to gmitch about it. The guy makes some awesome stuff.

 

[roberts]

jock where u get the mgw one? any vendors sell it?

 

[JeremyH]

My mgw shifter on my 6060 will be coming off soon after Christmas when I drop the trans to get it worked on. To my knowledge mgw only sells directly.

 

[stkjock]

MGW a sells it. Not sure if others do.

 

[Metallicats]

thanks to all of you for your info and experience and merry christmas from Montreal Canada

I'll consider that. Finally got the 6060 in yesterday.

I avoid SVTP like the plague. Can't stand the ownership.

It's gonna take a hell of a shifter to beat an mgw lol

I love my 6060 swap except for the reverse lock out that I haven't done yet
